6 could use lots of photosynthates, but contributed little to the accumulation of biomass. 4. Photosynthetic rate of P. armeniacum decreased a little at the noon, and the highest photosynthetic rate was observed at 10:00h in the greenhouse. The variation of photosynthetic rate was in the same trend as stomatal conductance. Higher relative humidity seemed to be the key for higher photosynthetic rate in P. armeniacum. 5. The photosynthetic capacity of C. flavum was statistically larger than that of P. armeniacum. The lower leaf photosynthetic capacity of P. armeniacum was related to its lower leaf nitrogen concentration,leaf phosphorus concentration and enzyme activities. Meanwhile, the extremely lower stomatal conductance and internal mesophyll conductance might greatly limit the photosynthetic capacity of P. armeniacum. The lower stomatal conductance and photosynthetic rate of Paphiopedilum might partially caused by the lack of chloroplasts in the guard cell of Paphiopedilum. Compared with C. flavum, P. armeniacum was more fond of shade environment.6. The short longevity leaf of Cypripedium had bigger photosynthetic capacity and greater potential for fast growth. But the longer LL of Paphiopedilum enhanced nutrient conservation which could compensate its lower photosynthetic capacity. The short longevity leaf of Cypripedium usually had higher photosynthetic rate per unit leaf mass and dark respiration rate, and photosynthetic capacity decreased fast with leaf age. However, for Paphiopedilum, the situation was the opposite. 7. Compared with Cypripedium, Paphiopedilum had higher water use efficiency and lower photosynthetic nitrogen use efficiency. 8. The leaf of Paphiopedilum had higher leaf construction cost and longer repayment time than that of Cypripedium. The leaf structures and physiological functions of Paphiopedilum and Cypripedium reflected the adaptation to their habitats. The leaf morphological and physiological evolution of Paphiopedilum was related to water and resource-conserving traits in the karst habitat. The leaf traits of Cypripedium were the adaptation to the environment rich in water and nutrients but easy to change with seasons.Our results provided evidence of divergent evolution of congeneric orchids under natural selection.","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=Carbohydrate%2BChemistry&order=desc&&fq=dc.project.title_filter%3APaphiopedilum%5C+and%5C+Cypripedium%5C+are%5C+close%5C+relatives%5C+belonging%5C+to%5C+the%5C+subfamily%5C+Cypripedioideae.%5C+However%2C%5C+they%5C+undergo%5C+considerable%5C+divergence%5C+in%5C+the%5C+aspects%5C+of%5C+life%5C+forms%2C%5C+leaf%5C+traits%5C+and%5C+habitats.%5C+In%5C+present%5C+study%2C%5C+leaf%5C+morphologies%5C+and%5C+anatomical%5C+structures%2C%5C+leaf%5C+lifespans%2C%5C+leaf%5C+mass%5C+per%5C+area%2C%5C+photosynthetic%5C+capacities%2C%5C+nutrient%5C+use%5C+efficiencies%2C%5C+leaf%5C+construction%5C+costs%2C%5C+and%5C+maintenance%5C+costs%5C+were%5C+investigated%5C+to%5C+understand%5C+the%5C+relationship%5C+between%5C+leaf%5C+traits%5C+and%5C+ecophysiological%5C+adaptability%5C+of%5C+the%5C+two%5C+types%5C+of%5C+plants%5C+and%5C+explore%5C+the%5C+related%5C+ecological%5C+and%5C+evolutionary%5C+significances.%5C+The%5C+results%5C+suggest%5C+that%5C%3A1.%5C+Compared%5C+with%5C+Cypripedium%2C%5C+Paphiopedilum%5C+was%5C+characterized%5C+by%5C+drought%5C+tolerance%5C+from%5C+its%5C+leaf%5C+anatomical%5C+structure%5C+including%5C+fleshy%5C+leaf%2C%5C+thicker%5C+surface%5C+cuticle%2C%5C+huge%5C+abaxial%5C+epidermis%5C+cells%2C%5C+differentiation%5C+of%5C+palisade%5C+and%5C+spongy%5C+mesophyll%5C+layers%2C%5C+the%5C+prominent%5C+of%5C+mucilaginous%5C+substances%2C%5C+supportable%5C+leaf%5C+main%5C+vein%2C%5C+lower%5C+total%5C+stoma%5C+area%5C+%5C%28%25%5C%29%2C%5C+sunken%5C+stomata%5C+and%5C+special%5C+stoma%5C+structure.%5C+Leaf%5C+morphologies%5C+and%5C+structures%5C+of%5C+Cypripedium%5C+were%5C+to%5C+the%5C+contrary%5C+of%5C+Paphiopedilum.%5C+Leaf%5C+morphologies%5C+and%5C+structures%5C+embodied%5C+the%5C+adaptation%5C+to%5C+the%5C+environment%5C+in%5C+both%5C+Paphiopedilum%5C+and%5C+Cypripedium.%5C+Our%5C+results%5C+also%5C+confirmed%5C+the%5C+previous%5C+observation%5C+that%5C+Paphiopedilum%5C+was%5C+the%5C+only%5C+genus%5C+that%5C+did%5C+not%5C+possess%5C+guard%5C+cell%5C+chloroplasts.2.%5C+The%5C+photosynthetic%5C+capacities%5C+of%5C+P.%5C+armeniacum%5C+leaves%5C+were%5C+different%5C+with%5C+different%5C+leaf%5C+ages.%5C+The%5C+highest%5C+photosynthetic%5C+capacity%5C+occurred%5C+in%5C+leaf%5C+age%5C+1%5C-2%5C+years%2C%5C+followed%5C+by%5C+1%5C+year%5C+and%5C+2%5C-4%5C+years.%5C+The%5C+highest%5C+photosynthetic%5C+capacity%5C+of%5C+C.%5C+flavum%5C+occurred%5C+in%5C+leaf%5C+age%5C+60%5C+days%2C%5C+followed%5C+by%5C+30%5C+days%2C%5C+90%5C+days%5C+and%5C+120%5C+days.%5C+3.%5C+Photosynthetic%5C+capacities%5C+of%5C+different%5C+leaf%5C+positions%5C+were%5C+mainly%5C+affected%5C+by%5C+leaf%5C+ages%5C+in%5C+P.%5C+armeniacum.%5C+The%5C+four%5C+leaves%5C+lying%5C+on%5C+the%5C+top%5C+did%5C+the%5C+most%5C+accumulation%5C+of%5C+the%5C+assimilation%5C+products%5C+in%5C+the%5C+whole%5C+plant.%5C+The%5C+leaves%5C+of%5C+sequence%5C+number%5C+%3E%5C+6%5C+could%5C+use%5C+lots%5C+of%5C+photosynthates%2C%5C+but%5C+contributed%5C+little%5C+to%5C+the%5C+accumulation%5C+of%5C+biomass.%5C+4.%5C+Photosynthetic%5C+rate%5C+of%5C+P.%5C+armeniacum%5C+decreased%5C+a%5C+little%5C+at%5C+the%5C+noon%2C%5C+and%5C+the%5C+highest%5C+photosynthetic%5C+rate%5C+was%5C+observed%5C+at%5C+10%5C%3A00h%5C+in%5C+the%5C+greenhouse.%5C+The%5C+variation%5C+of%5C+photosynthetic%5C+rate%5C+was%5C+in%5C+the%5C+same%5C+trend%5C+as%5C+stomatal%5C+conductance.%5C+Higher%5C+relative%5C+humidity%5C+seemed%5C+to%5C+be%5C+the%5C+key%5C+for%5C+higher%5C+photosynthetic%5C+rate%5C+in%5C+P.%5C+armeniacum.%5C+5.%5C+The%5C+photosynthetic%5C+capacity%5C+of%5C+C.%5C+flavum%5C+was%5C+statistically%5C+larger%5C+than%5C+that%5C+of%5C+P.%5C+armeniacum.%5C+The%5C+lower%5C+leaf%5C+photosynthetic%5C+capacity%5C+of%5C+P.%5C+armeniacum%5C+was%5C+related%5C+to%5C+its%5C+lower%5C+leaf%5C+nitrogen%5C+concentration%2Cleaf%5C+phosphorus%5C+concentration%5C+and%5C+enzyme%5C+activities.%5C+Meanwhile%2C%5C+the%5C+extremely%5C+lower%5C+stomatal%5C+conductance%5C+and%5C+internal%5C+mesophyll%5C+conductance%5C+might%5C+greatly%5C+limit%5C+the%5C+photosynthetic%5C+capacity%5C+of%5C+P.%5C+armeniacum.%5C+The%5C+lower%5C+stomatal%5C+conductance%5C+and%5C+photosynthetic%5C+rate%5C+of%5C+Paphiopedilum%5C+might%5C+partially%5C+caused%5C+by%5C+the%5C+lack%5C+of%5C+chloroplasts%5C+in%5C+the%5C+guard%5C+cell%5C+of%5C+Paphiopedilum.%5C+Compared%5C+with%5C+C.%5C+flavum%2C%5C+P.%5C+armeniacum%5C+was%5C+more%5C+fond%5C+of%5C+shade%5C+environment.6.%5C+The%5C+short%5C+longevity%5C+leaf%5C+of%5C+Cypripedium%5C+had%5C+bigger%5C+photosynthetic%5C+capacity%5C+and%5C+greater%5C+potential%5C+for%5C+fast%5C+growth.%5C+But%5C+the%5C+longer%5C+LL%5C+of%5C+Paphiopedilum%5C+enhanced%5C+nutrient%5C+conservation%5C+which%5C+could%5C+compensate%5C+its%5C+lower%5C+photosynthetic%5C+capacity.%5C+The%5C+short%5C+longevity%5C+leaf%5C+of%5C+Cypripedium%5C+usually%5C+had%5C+higher%5C+photosynt

and Cypripedium，known as slipper orchids in horticulture, belong to the subfamily Cypripedioideae of the Orchidaceae. Although they are closely related phylogenetically, there are significant differences in leaf traits and geographical distributions between two genera. This dissertation includes the following sections: (1) the leaf functional traits were compared in six species of the two genera; (2) the physiological responses of P. armeniacum to different water regimes, light regimes and low temperature; (3) the leaf phenotypic plastics of C. flavum in response to the different light condition and the photosynthetic characteristics of three Cypripedium species during sexual reproduction. The aims are to understand the convergent and divergent evolution between the two genera in leaf traits and their adaptive significances, and the leaf plastic responses to different levels of resources. Such information could provide scientific basis for conservation and domestication of Paphiopedilum and Cypripedium. The results are given below:1. Compared with Paphiopedilum, Cypripedium showed significantly higher photosynthetic rate (Pmax), leaf nitrogen content (Na), photosynthetic nitrogen utilization (PNUE), the fractions of leaf nitrogen partitioning in carboxylation (PC) and bioenergetics (PB), specific leaf area (SLA), ratio of leaf chlorophyll a and b (Chla/b), but significantly lower leaf construction cost (CC) and the ratio of leaf carbon content to leaf nitrogen (C/N). These leaf traits of Cypripedium are considered as the adaptation to short growing period and rich soil nutrients in the alpine habitats. Conversely, the long life span, low Pmax and mesophyll conductance (gm) but high SLA, CC and C/N in Paphiopedilum indicated that the adaptation to low-light, limited-nutrient habitat in the limestone area. As a sympatric species of Paphiopedilum, C. lentiginosum not only kept phylogenetically leaf traits of Cypripedium, suchas stomatal conductance (gs), Pmax, PNUE and dormant in winter, but also possessed many leaf traits which is similar to that in Paphiopedilum, such as relative stomatal limitations (RSL), gm, the ratio of leaf chlorophyll a and b (Chl a/b), fraction of leaf nitrogen allocated to light-harvesting components (PL). These results indicated the convergent and divergent evolution of Paphiopedilum and Cypripedium in leaf traits.2. Paphiopedilum. armeniacum exhibited a high plasticity of leaf photosynthetic function in response to different light regimes, but the responses changes with the time. Due to grow under low light habitat, P. armeniacum grown under 50% shade (HL) had the significantly lowest Pmax than the plants grown under 75% shade (ML) and 95% shade (LL) after six months. However, after twelve months, the Pmax of the plants grown under HL increased significantly and then became the highest one among three levels of light. It is also found that leaf dry mass per unit area (LMA), leaf stomatal conductance (gS), internal mesophyll conductance (gm), the fraction of leaf nitrogen partitioning in photosynthetic carboxylation (PC), bioeneretics (PB) were greatly influenced by irradiance. The plants grown under HL increased gS, gm, PC, PB to increase Pmax. In addition, the plants grown under HL had the highest ratio of total chlorophyll content to total Carotenoid content (Car/Chl) while the plants grown under LL had the lowest ratio of leaf chlorophyll a and b (Chl a/b). As a result, plasticity of leaf photosynthetic physiology of P. armeniacum in response to different light regimes depended largely on leaf nitrogen partitioning and leaf structure. As for the numbers of flowering and fruiting, ML was the best light level.3. The responses of P. armeniacum to different water regimes were not significantly different. But the Pmax and the maximum photochemical efficiency of PSⅡ (Fv/Fm) decreased with the increased frequency of watering. The reasons were that the plants have high respiration rate (Rd) and make more use of light energy to oxidation cycle. The plants watered every eight days (MW) and every twenty days (LW) had higher Pmax than the plant watered every four days (HW) mainly because of the higher PC and PB. Besides, the leaves of P. armeniacum had excellent property for holding water also contributed to the high photosynthetic capacity.4. Paphiopedilum. armeniacum was very sensitive to the low temperature. The plants significantly decreased photosynthetic capacity after grown under 4℃ for three days and the photosynthetic machinery was destroyed after fifteen days. The photosynthetic capacity of P. armeniacum exhibited no change at 10℃ and 15℃.5. Cypripedium flavum of four habitats (DB, XRD, XZD and TSQ) with different light intensity exhibited different photosynthetic characteristics after transplanted to the same environment in Kunming. Among the habitats, the light intensity of DB was the highest while XRD was the lowest. The light intensity of XZD and TSQ were not significantly difference. Among all the plants in Kunming, the plants of DB had the significantly highest Pmax but the plants of XRD had the lowest Pmax. The light saturation point (LSP) and photosynthetic nitrogen use efficiency (PNUE) agreed well with the light intensity of four habitats and contributed to the high Pmax of DB. The LMA, Chl and leaf nitrogen content were not different among all the plants. C. flavum exhibited sensitively response to the change of light in leaf construction while kept the plasticity of leaf photosynthetic characteristics which developed from its own habitat.6. The photosynthetic capacity of C. tibeticum and C. flavum were significantly increased at the flowering stage. For these two species, the significantly increased Amax were closely related to the maximum carboxylation rate by ribulose-1, 5-bisphosphate carboxylase/oxygenase (Vcmax), photon saturated rate of electron transport (Jmax), the rate of triose phosphate utilization (TPU) and actual quantum efficiency of the photosystem II photochemistry (ΦPSII) respectively. However, flowering almost did not affect the photosynthetic capacity of C. guttatum. C. guttatum had the smallest plant size, the leaf area, the volume of labellum and the volume of fruit, but the biggest fruit volume per leaf area among three species. These results indicated that for C. flavum and C. tibeticum there were a physiological mechanism in photosynthesis to compensate the cost of flowering as well as increased resource acquisitions, which would be beneficial to the survival or future flowering of the plant. C. gutattum could keep a steady photosynthetic capacity during life history. This kind of pattern could decrease the effect of the reproductive costs as much as possible. In contrast to C. flavum and C. tibeticum, C. gutattum possessed a more economical and effective reproductive pattern which maybe related to its wider distribution.In conclusion, Paphiopedilum and Cypripedium have significantly different leaf traits which agree well with their habitats and there is a divergent and convergent evolution between the two genera. P. armeniacum is much tolerant and responsive to varying water and light availability but very sensitivity to the low temperature. Confronting the suddenly change of light environment, C. flavum can respond sensitively to the change of light in leaf construction but the plasticity of leaf photosynthetic characteristics which developed from its own habitat can hold for the next growing season. In contrast to C. flavum and C. tibeticum, C. gutattum possesses a more economical and effective reproductive pattern which maybe related to its wider distribution. The study of the relationship between the two genera, the response and tolerance to the environmental factors of the two genera are important for understanding the adaptation and evolution of the

contain the entire genetic information of plants, which enable to develop the technology of seed preservation for the conservation of plant diversity. The mechanism of cell death in seeds, which are induced by ageing of orthodox seeds and desiccation of recalcitrant and intermediate seeds are two important areas in seed biology but poorly understood.Those two areas were investigated in this dissertation, and Pisum sativum, Camellia sinensis var. assamica, Castanea mollissima were chosen to represent orthodox, intermediate and recalcitrant seeds respectively as studied models. Biophysical, biochemical and molecular methods were employed to investigate the cell death mechanism during seeds ageing and desiccation.First of all, Ageing induced porgrammed cell death in seeds.The morphology change, nucleic acid integrity, and gene expression during ageing of Pisum sativum seeds were investigated.The data above confirmed that PCD is an underlying mechanism of seed mortality. Moreover, glutathione played an important function during seeds ageing.An increase in glutathione redox potential (EGSSG/2GSH) while seed lost viability was discovered during ageing of P. sativum seeds. Seed viability decreased 50% when EGSSG/2GSH attained values of -180 to -160 mV, which proved that EGSSG/2GSH was a marker for seeds viability. Secondely,Reactive oxygen species plays different roles in the seed germination after desiccation. After different desiccation treatments on the tea (C. sinensis var. assamica) seeds, the relationship between ROS dose and the viability of seeds after desication treatment was investigated. The results demonstrated that the presence of ROS could released the damage of desiccation on the tea seeds. Thridly,the composition of membrane lipid species and the change during desiccation in seeds with different storage behavior. Cell membrane is very sensitive to environment, and adjust the composition of lipid molecules is one of the main methord for cell to response the environmental changes. There is a rule that phosphatidic acid (PA), with special structure, is very sensitive to temperature and water stress, and the increase of PA content indicates the damage of the cell membrane. ESI/MS-MS technology was used to analysis and compare the composition and changes membrane lipid species during desiccation treatments of Pisum sativum, Camellia sinensis var. assamica, Castanea mollissima seeds which represented orthodox, intermediate and recalcitrant seeds respectively. The results showed that the responses of PA to dehydration in embryonic axis of orhtordox and recalcitrant seeds were different. The percentage increasement of PA in orthodox seed during desiccation was not incredible and the level of PA decreased and achieved the same level as controled, while PA level increased dramatically without showing any decrease trend in recalcitrant seed, which indicated that the damage to membrane of recalcitrant seeds was inevitable. Those results indicted that the dehydration might induced reversible memebrane damage in the orthodox seed, which may result in no affect on the seed viability, while it might induced irreversible membrane damage to the recalcitrant seed, which inducned the dramatically reduce of viabiligy and cell death in the end. It was the first time to investigate and analysis systematically the composition and changes of membrane lipids of different storage behavior seeds during desiccation. It was first time to report the relationship between PA and the seeds storeage and the change of PA level in seeds could be used as the marker to diagnose.the property of seeds for desiccation

reaction of transphosphatidylation is which phospholipase D catalyzes hydrolytic cleavage of the terminal phosphate diester bond of glycerophosphatides, transfer the phosphatidyl moiety of a phospholipids to a primary alcohol or water, producing phosphatidyl alcohol or phosphatidic acid (PtdOH). Although this reaction plays important role in regulating physical process in plants and anminals, the pathway involved in and detailed regulation mechanism are still unknown or not clear. There are three factors which can affect transphosphatidylation, substrates, enzymes and products. This paper intended to uncover the physical effect of the reaction in detail by changing two indispensable factors, the type of substrate and the PLDs. This paper consist of three researches, the first one, changing the accept substrate of the reaction aims to study the relationship between the structure of alcohols and the physical effect, to reveal the significance of the reaction; secondly, using genetic methods to regulate the expression of PLDs mediating transphosphatidylation intends to study its roles in regulating senescence; thirdly, reducing mostly PA derived from PLDs by addition 1-Butanol try to study the effect of PLD-derived PA on phosphate starvation. 1. Initial research of the effect of alcohols on the palnt growth. In this study, we study on the effect of alcohols on Arabidopsis seed germination, seeding growth and membrane lipids molecules, the metabolic procees and signaling pathway invoved in plant responding to 1-Butanol. According to the results we observed, the toxicity of alcohols and its polarity is positively correlated; the toxicity of alcohols to plants may be related with the butanoate and propanoate metabolic pathway rather than transphosphatidylation, the increase of free IAA is contributed to the resistance to 1-Butanol for WS ecotype Arabidopsis thaliana. Futhermore, five 1-Butanol insensitive mutants have obtained and the mutant sites has identified. Under the same concentration 1-Butanol stress, the five mutants are in better condition no matter physical and chemical level or cellular levels compared to wild-type Arabidopsis thaliana. It is believed that the five mutants definitely provide direct evidence for us to uncover the mechanism of the toxicity of alcohols to plants. 2. The change pattern of the membrane lipid molecules responding to the phytohormones-promoted detached Arabidopsis leaves and the role of PLDα1 and PLDδ in regulating this process. The reason for PLDα1-antisense mutant and PLDδ-knockout mutant delaying phytohormone-promoted senescence may be PLDα1 and PLDδ are response to the ABA and ethylene sinaling; PLDα1-or PLDδ-derived PA contributes to reactive oxygen species (ROS) accumulation; PLDα1-antisense mutant and PLDδ-knockout mutant have higher level of indole-3-acrtic acid (IAA) and zeatin riboside (ZR) level but lower level of abscisic acid (ABA) and jasmonic acid (JA) compared to wild-type Col and wild-type WS, respectively, which is favorable to retard the phytohormone-promoted detached leaves senescence. 3. Application tert-butanol increase the efficiency of phosphate utilization and absord when the phosphate-limited. The seedinges phosphate-starved or not exposed to 1-Butanol was subjected to lethal stress. However, in low phosphate condition, application of tert-butanol lower anthocyanin accumulation, increase the phosphate levels and the siliques number, in a word, tert-butanol attenuates the symptom of phosphate-starved induced. It is suggested that tert-Butanol can increase the utilization and absord efficiency of the limited phosphate, however, more evidences are needed to prove the mechanism.","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=Carbohydrate%2BChemistry&order=desc&&fq=dc.project.title_filter%3AThe%5C+reaction%5C+of%5C+transphosphatidylation%5C+is%5C+which%5C+phospholipase%5C+D%5C+catalyzes%5C+hydrolytic%5C+cleavage%5C+of%5C+the%5C+terminal%5C+phosphate%5C+diester%5C+bond%5C+of%5C+glycerophosphatides%2C%5C+transfer%5C+the%5C+phosphatidyl%5C+moiety%5C+of%5C+a%5C+phospholipids%5C+to%5C+a%5C+primary%5C+alcohol%5C+or%5C+water%2C%5C+producing%5C+phosphatidyl%5C+alcohol%5C+or%5C+phosphatidic%5C+acid%5C+%5C%28PtdOH%5C%29.%5C+Although%5C+this%5C+reaction%5C+plays%5C+important%5C+role%5C+in%5C+regulating%5C+physical%5C+process%5C+in%5C+plants%5C+and%5C+anminals%2C%5C+the%5C+pathway%5C+involved%5C+in%5C+and%5C+detailed%5C+regulation%5C+mechanism%5C+are%5C+still%5C+unknown%5C+or%5C+not%5C+clear.%5C+There%5C+are%5C+three%5C+factors%5C+which%5C+can%5C+affect%5C+transphosphatidylation%2C%5C+substrates%2C%5C+enzymes%5C+and%5C+products.%5C+This%5C+paper%5C+intended%5C+to%5C+uncover%5C+the%5C+physical%5C+effect%5C+of%5C+the%5C+reaction%5C+in%5C+detail%5C+by%5C+changing%5C+two%5C+indispensable%5C+factors%2C%5C+the%5C+type%5C+of%5C+substrate%5C+and%5C+the%5C+PLDs.%5C+This%5C+paper%5C+consist%5C+of%C2%A0three%5C+researches%2C%5C+the%5C+first%5C+one%2C%5C+changing%5C+the%5C+accept%5C+substrate%5C+of%5C+the%5C+reaction%5C+aims%5C+to%5C+study%5C+the%5C+relationship%5C+between%5C+the%5C+structure%5C+of%5C+alcohols%5C+and%5C+the%5C+physical%5C+effect%2C%5C+to%5C+reveal%5C+the%5C+significance%5C+of%5C+the%5C+reaction%5C%3B%5C+secondly%2C%5C+using%5C+genetic%5C+methods%5C+to%5C+regulate%5C+the%5C+expression%5C+of%5C+PLDs%5C+mediating%5C+transphosphatidylation%5C+intends%5C+to%5C+study%5C+its%5C+roles%5C+in%5C+regulating%5C+senescence%5C%3B%5C+thirdly%2C%5C+reducing%5C+mostly%5C+PA%5C+derived%5C+from%5C+PLDs%5C+by%5C+addition%5C+1%5C-Butanol%5C+try%5C+to%5C+study%5C+the%5C+effect%5C+of%5C+PLD%5C-derived%5C+PA%5C+on%5C+phosphate%5C+starvation.%5C+1.%5C+Initial%5C+research%5C+of%5C+the%5C+effect%5C+of%5C+alcohols%5C+on%5C+the%5C+palnt%5C+growth.%5C+In%5C+this%5C+study%2C%5C+we%5C+study%5C+on%5C+the%5C+effect%5C+of%5C+alcohols%5C+on%5C+Arabidopsis%5C+seed%5C+germination%2C%5C+seeding%5C+growth%5C+and%5C+membrane%5C+lipids%5C+molecules%2C%5C+the%5C+metabolic%5C+procees%5C+and%5C+signaling%5C+pathway%5C+invoved%5C+in%5C+plant%5C+responding%5C+to%5C+1%5C-Butanol.%5C+According%5C+to%5C+the%5C+results%5C+we%5C+observed%2C%5C+the%5C+toxicity%5C+of%5C+alcohols%5C+and%5C+its%5C+polarity%5C+is%5C+positively%5C+correlated%5C%3B%5C+the%5C+toxicity%5C+of%5C+alcohols%5C+to%5C+plants%5C+may%5C+be%5C+related%5C+with%5C+the%5C+butanoate%5C+and%5C+propanoate%5C+metabolic%5C+pathway%5C+rather%5C+than%5C+transphosphatidylation%2C%5C+the%5C+increase%5C+of%5C+free%5C+IAA%5C+is%5C+contributed%5C+to%5C+the%5C+resistance%5C+to%5C+1%5C-Butanol%5C+for%5C+WS%5C+ecotype%5C+Arabidopsis%5C+thaliana.%5C+Futhermore%2C%5C+five%5C+1%5C-Butanol%5C+insensitive%5C+mutants%5C+have%5C+obtained%5C+and%5C+the%5C+mutant%5C+sites%5C+has%5C+identified.%5C+Under%5C+the%5C+same%5C+concentration%5C+1%5C-Butanol%5C+stress%2C%5C+the%5C+five%5C+mutants%5C+are%5C+in%5C+better%5C+condition%5C+no%5C+matter%5C+physical%5C+and%5C+chemical%5C+level%5C+or%5C+cellular%5C+levels%5C+compared%5C+to%5C+wild%5C-type%5C+Arabidopsis%5C+thaliana.%5C+It%5C+is%5C+believed%5C+that%5C+the%5C+five%5C+mutants%5C+definitely%5C+provide%5C+direct%5C+evidence%5C+for%5C+us%5C+to%5C+uncover%5C+the%5C+mechanism%5C+of%5C+the%5C+toxicity%5C+of%5C+alcohols%5C+to%5C+plants.%5C+2.%5C+The%5C+change%5C+pattern%5C+of%5C+the%5C+membrane%5C+lipid%5C+molecules%5C+responding%5C+to%5C+the%5C+phytohormones%5C-promoted%5C+detached%5C+Arabidopsis%5C+leaves%5C+and%5C+the%5C+role%5C+of%5C+PLD%CE%B11%5C+and%5C+PLD%CE%B4%5C+in%5C+regulating%5C+this%5C+process.%5C+The%5C+reason%5C+for%5C+PLD%CE%B11%5C-antisense%5C+mutant%5C+and%5C+PLD%CE%B4%5C-knockout%5C+mutant%5C+delaying%5C+phytohormone%5C-promoted%5C+senescence%5C+may%5C+be%5C+PLD%CE%B11%5C+and%5C+PLD%CE%B4%5C+are%5C+response%5C+to%5C+the%5C+ABA%5C+and%5C+ethylene%5C+sinaling%5C%3B%5C+PLD%CE%B11%5C-or%5C+PLD%CE%B4%5C-derived%5C+PA%5C+contributes%5C+to%5C+reactive%5C+oxygen%5C+species%5C+%5C%28ROS%5C%29%5C+accumulation%5C%3B%5C+PLD%CE%B11%5C-antisense%5C+mutant%5C+and%5C+PLD%CE%B4%5C-knockout%5C+mutant%5C+have%5C+higher%5C+level%5C+of%5C+indole%5C-3%5C-acrtic%5C+acid%5C+%5C%28IAA%5C%29%5C+and%5C+zeatin%5C+riboside%5C+%5C%28ZR%5C%29%5C+level%5C+but%5C+lower%5C+level%5C+of%5C+abscisic%5C+acid%5C+%5C%28ABA%5C%29%5C+and%5C+jasmonic%5C+acid%5C+%5C%28JA%5C%29%5C+compared%5C+to%5C+wild%5C-type%5C+Col%5C+and%5C+wild%5C-type%5C+WS%2C%5C+respectively%2C%5C+which%5C+is%5C+favorable%5C+to%5C+retard%5C+the%5C+phytohormone%5C-promoted%5C+detached%5C+leaves%5C+senescence.%5C+3.%5C+Application%5C+tert%5C-butanol%5C+increase%5C+the%5C+efficiency%5C+of%5C+phosphate%5C+utilizat

thesis includes four chapters: Chapters 1 and 2 cover bioactive constituents of two traditional Chininese medicines of Ding-Zhi-Yuan prescription: Acorus tatarinowii Schott. and Poria cum Radix Pini. Chapter 3 introduces chemical components of flavonoids from the gum of Cerasus conradinae. In the last chapter, the research progress of Acorus was reviewed. As a result, 60 compounds were isolated from these plants, and eight of them were identified as new ones. Their structures were established on the basis of spectroscopic data. The types of these compounds include phenylpropanoids, lignans, flavonoids, sesquiterpenoids, alkaloids, and steroids.Chapter 1 introduced the chemical constitutents of Acorus tatarinowii Schott. Acorus tatarinowii Schott is a famous traditional Chinese medicine possessing anticonvulsive,spasmolytic, and neuroprotective effects. To study its pharmacological mechanism, 47 compounds, including 7 new ones, were isolated from this herb. AlphaScreen cAMP assay showed that six phenylpropanoids significantly increased cAMP level at the concentration of 50 µM. Two novel spiro-alkaloids inhibited high glucose-induced ROS production in mesangial cells. Besides, their anti-oxidant activities were dose-dependent and reached to the maximum at 10 μM and 50 μM, respectively.Chapter 2 introduced the chemical constitutents of Poria cum Radix Pin. Poria cum Radix Pini is the xylem of Poria cocos (Schw.) Wolf. As a traditional Chinese medicine, it has the effects for treatment of palpitation, forgettery, insomnia and other diseases. Chemical investigation about it resulted in 9 compounds and 1 compound was elucidated to be new. Chater 3 introduced the chemical constituents of flavonoids from the gum of Cerasus conradina.ere isolated from the gum ofCerasus conradinae. The fruits of Cerasus conradina were used to deal with heart failure, beriberi and edema. Because of frostibe, pest, and mechanical damage, Cerasus conradin excrete lots of gum in winter.

In this paper, the megasporogenesis and development of female gametophyte, seed morphological traits and seed germination, seed conservation, micropropagation and acclimatization of this species were studied. Combined with the published results of cytology, molecular genetics and other researches,the mechanisms of extinction, basic biology and technology of germplasm conservation and acclimatization of T. doichangensis were discussed. The main results are summarized as follows:1. Megasporogenesis and development of female gametophyte，Stamens exist under the stigma of T. doichangensis, and the pollen is aborted on the later development stage of pistil, therefore, the pistillate flower in function is hermaphrodite flower in morphology. The ovule is anatropous, bitegmic and crassinucellate. The primary archesporium is hypodermal and single-celled and the sporogenous cell of the nucellus functions directly as a megaspore mother cell which goes meiosis to form a linear tetrad. The chalazal megaspore of the tetrad is functional. The development of embryo sac conforms to the polygonum type. There are six ovules in the ovary of T. doichangensis, and only one develops into a seed in normal fruits. In the process of megasporogenesis and development of female gametophyte, there are several links of abortion, and 93.3% of mature embryo sacs is aborted.2. Morphological characters and germination of seeds，Most of the variation occurred among individual trees within populations in seed morphological traits (length, width and 1000-seed weight) and germination-related indices (germination percentage, germination index and vigor index). In addition, the variation in percentage of well-developed seeds among populations and among individual trees within populations is equal, each accounting for 48%. Each of seed morphological traits has significantly positive correlation with each other (p < 0.01), but they have no significant correlation with percentage of well-developed seeds and germination-related indices. In the same batch of seeds of T. doichangensis, there are light-colored and dark-colored seed coats, and development of light-colored seeds is significantly poorer than that of dark-colored seeds.The sensitivity of seeds to high temperature varys in different stages of seed imbibition. In each stage, heat acclimatization don’t increase germination percentage, germination index and fresh weight of seedlings. If the distilled water is substituted by solution of SA during seed imbibition, seed germination and germination index after heat shock are not significantly different from control, but they are significantly higher than that of other treatments. Moreover, when the seeds are treatmented with SA, the fresh weight of seedlings is significantly higher than that of control and other treatments.3. Seed conservation，Seeds of T. doichangensis belong to orthodox seeds which can tolerate certain level of dehydration. The condition of low temperature and low water content of seeds is conducive to seed conservation.Germination of fresh seeds shows significant variation among populations, howerer, germination of the seeds after storage for one year in room temperature shows no significant variation among populations.High temperature and high relative humidity damages the seeds more severely than high temperature does. In addition, low water content of seeds enable the seeds to be more tolerant to high temperature.The electrical conductivity, dehydrogenase activity and germination percentage have no significant correlation with each other.4. Micropropagation and in vitro conservation，Cotyledonary nodes are a kind of efficient explants. Low salt media are conducive to shoot propagation and root induction.The maximum multiplication rate (20-25 shoots/explant within 4 months) is achieved on quarter-strength Murashige and Skoog (1/4 MS) medium supplemented with 1 mg·L-1 6-benzyladenine (6-BA) and 0.05 mg·L-1 α-naphthaleneacetic acid (NAA).Rooting is promoted by auxins, however, IBA alone or low concentrations of NAA are preferable due to small amount of callus induced. The research has established an efficient protocol for micropropagation of T. doichangensis, and it provides technology support for in vitro conservation of special germplasm of the species.5. Acclimatization，Quercus variabilis, Cyclobalanopsis glaucoides and T. doichangensis belong to the family of Fagaceae, and the natural distribution ranges of the 3 species are decreasing in turn. The research suggests that the ranges of temperature tolerance of the 3 species are decreasing corresponding to their distribution ranges.The high and low semi-lethal temperature of one-year old T. doichangensis is 49.5℃ and -5℃ respectively. It suggests that T. doichangensis has a wide range of basic temperature tolerance. Short-term heat and cold acclimatization cannot expand the range of temperature tolerance. It can be inferred that T. doichangensis may lack induced tolerance to temperature. Under proper conditions, ABA can increase the cold tolerance, and SA can increase the heat tolerance of leaf discs of T. doichangensis.","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=Carbohydrate%2BChemistry&order=desc&&fq=dc.project.title_filter%3ATrigonobalanus%5C+doichangensis%5C+is%5C+an%5C+endangered%5C+plant.%5C+In%5C+this%5C+paper%2C%5C+the%5C+megasporogenesis%5C+and%5C+development%5C+of%5C+female%5C+gametophyte%2C%5C+seed%5C+morphological%5C+traits%5C+and%5C+seed%5C+germination%2C%5C+seed%5C+conservation%2C%5C+micropropagation%5C+and%5C+acclimatization%5C+of%5C+this%5C+species%5C+were%5C+studied.%5C+Combined%5C+with%5C+the%5C+published%5C+results%5C+of%5C+cytology%2C%5C+molecular%5C+genetics%5C+and%5C+other%5C+researches%2Cthe%5C+mechanisms%5C+of%5C+extinction%2C%5C+basic%5C+biology%5C+and%5C+technology%5C+of%5C+germplasm%5C+conservation%5C+and%5C+acclimatization%5C+of%5C+T.%5C+doichangensis%5C+were%5C+discussed.%5C+The%5C+main%5C+results%5C+are%5C+summarized%5C+as%5C+follows%5C%3A1.%5C+Megasporogenesis%5C+and%5C+development%5C+of%5C+female%5C+gametophyte%EF%BC%8CStamens%5C+exist%5C+under%5C+the%5C+stigma%5C+of%5C+T.%5C+doichangensis%2C%5C+and%5C+the%5C+pollen%5C+is%5C+aborted%5C+on%5C+the%5C+later%5C+development%5C+stage%5C+of%5C+pistil%2C%5C+therefore%2C%5C+the%5C+pistillate%5C+flower%5C+in%5C+function%5C+is%5C+hermaphrodite%5C+flower%5C+in%5C+morphology.%5C+The%5C+ovule%5C+is%5C+anatropous%2C%5C+bitegmic%5C+and%5C+crassinucellate.%5C+The%5C+primary%5C+archesporium%5C+is%5C+hypodermal%5C+and%5C+single%5C-celled%5C+and%5C+the%5C+sporogenous%5C+cell%5C+of%5C+the%5C+nucellus%5C+functions%5C+directly%5C+as%5C+a%5C+megaspore%5C+mother%5C+cell%5C+which%5C+goes%5C+meiosis%5C+to%5C+form%5C+a%5C+linear%5C+tetrad.%5C+The%5C+chalazal%5C+megaspore%5C+of%5C+the%5C+tetrad%5C+is%5C+functional.%5C+The%5C+development%5C+of%5C+embryo%5C+sac%5C+conforms%5C+to%5C+the%5C+polygonum%5C+type.%5C+There%5C+are%5C+six%5C+ovules%5C+in%5C+the%5C+ovary%5C+of%5C+T.%5C+doichangensis%2C%5C+and%5C+only%5C+one%5C+develops%5C+into%5C+a%5C+seed%5C+in%5C+normal%5C+fruits.%5C+In%5C+the%5C+process%5C+of%5C+megasporogenesis%5C+and%5C+development%5C+of%5C+female%5C+gametophyte%2C%5C+there%5C+are%5C+several%5C+links%5C+of%5C+abortion%2C%5C+and%5C+93.3%25%5C+of%5C+mature%5C+embryo%5C+sacs%5C+is%5C+aborted.2.%5C+Morphological%5C+characters%5C+and%5C+germination%5C+of%5C+seeds%EF%BC%8CMost%5C+of%5C+the%5C+variation%5C+occurred%5C+among%5C+individual%5C+trees%5C+within%5C+populations%5C+in%5C+seed%5C+morphological%5C+traits%5C+%5C%28length%2C%5C+width%5C+and%5C+1000%5C-seed%5C+weight%5C%29%5C+and%5C+germination%5C-related%5C+indices%5C+%5C%28germination%5C+percentage%2C%5C+germination%5C+index%5C+and%5C+vigor%5C+index%5C%29.%5C+In%5C+addition%2C%5C+the%5C+variation%5C+in%5C+percentage%5C+of%5C+well%5C-developed%5C+seeds%5C+among%5C+populations%5C+and%5C+among%5C+individual%5C+trees%5C+within%5C+populations%5C+is%5C+equal%2C%5C+each%5C+accounting%5C+for%5C+48%25.%5C+Each%5C+of%5C+seed%5C+morphological%5C+traits%5C+has%5C+significantly%5C+positive%5C+correlation%5C+with%5C+each%5C+other%5C+%5C%28p%5C+%3C%5C+0.01%5C%29%2C%5C+but%5C+they%5C+have%5C+no%5C+significant%5C+correlation%5C+with%5C+percentage%5C+of%5C+well%5C-developed%5C+seeds%5C+and%5C+germination%5C-related%5C+indices.%5C+In%5C+the%5C+same%5C+batch%5C+of%5C+seeds%5C+of%5C+T.%5C+doichangensis%2C%5C+there%5C+are%5C+light%5C-colored%5C+and%5C+dark%5C-colored%5C+seed%5C+coats%2C%5C+and%5C+development%5C+of%5C+light%5C-colored%5C+seeds%5C+is%5C+significantly%5C+poorer%5C+than%5C+that%5C+of%5C+dark%5C-colored%5C+seeds.The%5C+sensitivity%5C+of%5C+seeds%5C+to%5C+high%5C+temperature%5C+varys%5C+in%5C+different%5C+stages%5C+of%5C+seed%5C+imbibition.%5C+In%5C+each%5C+stage%2C%5C+heat%5C+acclimatization%5C+don%E2%80%99t%5C+increase%5C+germination%5C+percentage%2C%5C+germination%5C+index%5C+and%5C+fresh%5C+weight%5C+of%5C+seedlings.%5C+If%5C+the%5C+distilled%5C+water%5C+is%5C+substituted%5C+by%5C+solution%5C+of%5C+SA%5C+during%5C+seed%5C+imbibition%2C%5C+seed%5C+germination%5C+and%5C+germination%5C+index%5C+after%5C+heat%5C+shock%5C+are%5C+not%5C+significantly%5C+different%5C+from%5C+control%2C%5C+but%5C+they%5C+are%5C+significantly%5C+higher%5C+than%5C+that%5C+of%5C+other%5C+treatments.%5C+Moreover%2C%5C+when%5C+the%5C+seeds%5C+are%5C+treatmented%5C+with%5C+SA%2C%5C+the%5C+fresh%5C+weight%5C+of%5C+seedlings%5C+is%5C+significantly%5C+higher%5C+than%5C+that%5C+of%5C+control%5C+and%5C+other%5C+treatments.3.%5C+Seed%5C+conservation%EF%BC%8CSeeds%5C+of%5C+T.%5C+doichangensis%5C+belong%5C+to%5C+orthodox%5C+seeds%5C+which%5C+can%5C+tolerate%5C+certain%5C+level%5C+of%5C+dehydration.%5C+The%5C+condition%5C+of%5C+low%5C+temperature%5C+and%5C+low%5C+water%5C+content%5C+of%5C+seeds%5C+is%5C+conducive%5C+to%5C+seed%5C+conservation.Germination%5C+of%5C+fresh%5C+seeds%5C+shows%5C+significant%5C+variation%5C+among%5C+populations%2C%5C+howerer%2C%5C+germination%5C+of%5C+the%5C+seeds%5C+after%5C+storage%5C+for%5C+one%5C+year%5C+in%5C+room%5
