0.05) between wild (AR = 4.651), semi-cultivated (AR = 5.091) and cultivated (AR = 5.132) populations of C. taliensis, which suggested that the genetic background of long-lived woody plant was not easy to be changed, and there were moderate high gene flow between populations. However, there was a significant difference (P < 0.05) between wild (AR = 5.9) and cultivated (AR = 7.1) populations distributed in the same place in Yun county, Yunnan province, which may result from the hybridization and introgression of species in the tea garden and anthropogenic damages to the wild population. The hypothesis of hybrid origin of C. grandibracteata was tested by morphological and microsatellites analyses. Compared with other species, the locules in ovary of C. grandibracteata are variable, which showed a morphological intermediate and mosaic. Except one private allele, Ninety-nine percent alleles of C. grandibracteata were shared with these of C. taliensis and C. sinensis var. assamica. And C. grandibracteata was nested in the cluster of C. taliensis in the UPGMA tree. Conclusively, our results supported the hypothesis of hybrid origin of C. grandibracteata partly. The speciation of C. grandibracteata was derived from hybridization and asymmetrical introgression potentially. It is possible that C. taliensis was one of its parents, but it still needs more evidences to prove that C. sinensis var. assamica was another parent.","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=LEAF%2BTEMPERATURES&order=desc&&fq=dc.project.title_filter%3ACamellia%5C+taliensis%5C+%5C%28W.%5C+W.%5C+Smith%5C%29%5C+Melchior%2C%5C+a%5C+member%5C+of%5C+Camellia%5C+sect.%5C+Thea%2C%5C+is%5C+an%5C+indigenous%5C+species%5C+in%5C+local%5C+natural%5C+forest%5C+and%5C+has%5C+a%5C+long%5C+cultivative%5C+history%5C+in%5C+western%5C+Yunnan%5C+and%5C+its%5C+neighborhood%2C%5C+where%5C+the%5C+domestications%5C+of%5C+this%5C+species%5C+in%5C+different%5C+historical%5C+periods%5C+and%5C+in%5C+different%5C+ways%5C+can%5C+be%5C+found.%5C+C.%5C+taliensis%5C+is%5C+an%5C+important%5C+contributor%5C+to%5C+the%5C+formations%5C+of%5C+tea%5C+landraces%5C+by%5C+hybridization%5C+and%5C+introgression.%5C+In%5C+the%5C+present%5C+study%2C%5C+14%5C+microsatellite%5C+loci%5C+screened%5C+from%5C+37%5C+loci%5C+were%5C+used%5C+to%5C+explore%5C+the%5C+genetic%5C+diversity%5C+about%5C+this%5C+species%5C+with%5C+579%5C+samples%5C+from%5C+25%5C+populations%5C+%5C%2816%5C+wild%5C+populations%2C%5C+4%5C+semi%5C-cultivated%5C+populations%5C+and%5C+5%5C+cultivated%5C+populations%5C%29.%5C+At%5C+the%5C+same%5C+time%2C%5C+the%5C+potential%5C+hybrid%5C+speciation%5C+of%5C+C.%5C+grandibracteata%2C%5C+was%5C+investigated%5C+using%5C+39%5C+individuals%5C+from%5C+2%5C+populations%2C%5C+along%5C+with%5C+C.%5C+taliensis%5C+and%5C+C.%5C+sinensis%5C+var.%5C+assamica%5C+%5C%2883%5C+individuals%5C+from%5C+4%5C+populations%5C%29%5C+by%5C+the%5C+same%5C+microsatellite%5C+markers.%5C+C.%5C+taliensis%5C+had%5C+a%5C+moderate%5C+high%5C+level%5C+of%5C+genetic%5C+diversity%5C+%5C%28A%5C+%3D%5C+14.3%2C%5C+Ne%3D%5C+5.7%2C%5C+HE%5C+%3D%5C+0.666%2C%5C+I%5C+%3D%5C+1.753%2C%5C+AR%5C+%3D%5C+7.2%2C%5C+PPB%5C+%3D%5C+100%25%5C%29.%5C+This%5C+may%5C+result%5C+from%5C+several%5C+factors%5C+including%5C+K%5C-strategy%2C%5C+genetic%5C+background%2C%5C+gene%5C+flow%5C+between%5C+populations%2C%5C+hybridization%5C+and%5C+introgression%5C+among%5C+species.%5C+Between%5C+wild%5C+populations%5C+of%5C+C.%5C+taliensis%2C%5C+the%5C+gene%5C+flow%5C+was%5C+moderate%5C+high%5C+%5C%28Nm%5C+%3D%5C+1.197%5C%29%2C%5C+and%5C+genetic%5C+variation%5C+was%5C+less%5C+than%5C+20%25%5C+%5C%28GST%5C+%3D%5C+0.147%2C%5C+FST%5C+%3D%5C+0.173%5C%29%2C%5C+which%5C+was%5C+similar%5C+to%5C+other%5C+research%5C+results%5C+of%5C+long%5C-lived%5C+woody%5C+plants%2C%5C+and%5C+reflected%5C+the%5C+genetic%5C+structure%5C+of%5C+its%5C+ancestry%5C+to%5C+same%5C+extent.%5C+There%5C+was%5C+a%5C+high%5C+significant%5C+correlation%5C+between%5C+geographic%5C+distance%5C+and%5C+Nei%E2%80%99s%5C+genetic%5C+distance%5C+%5C%28r%5C+%3D%5C+0.372%2C%5C+P%5C+%3D%5C+0.001%5C%29%5C+of%5C+populations%2C%5C+which%5C+accorded%5C+with%5C+isolation%5C+by%5C+distance%5C+model.%5C+Inferring%5C+from%5C+Bayesian%5C+clustering%5C+of%5C+genotypes%2C%5C+all%5C+individuals%5C+of%5C+C.%5C+taliensis%5C+were%5C+divided%5C+into%5C+two%5C+groups%2C%5C+conflicting%5C+with%5C+the%5C+result%5C+based%5C+on%5C+Nei%E2%80%99s%5C+genetic%5C+distance%5C+and%5C+real%5C+geographic%5C+distribution%2C%5C+which%5C+suggested%5C+there%5C+were%5C+heavy%5C+and%5C+non%5C-random%5C+influences%5C+by%5C+human%5C+practices.%5C+According%5C+to%5C+allelic%5C+richness%2C%5C+there%5C+were%5C+no%5C+significant%5C+differences%5C+%5C%28P%5C+%3E%5C+0.05%5C%29%5C+between%5C+wild%5C+%5C%28AR%5C+%3D%5C+4.651%5C%29%2C%5C+semi%5C-cultivated%5C+%5C%28AR%5C+%3D%5C+5.091%5C%29%5C+and%5C+cultivated%5C+%5C%28AR%5C+%3D%5C+5.132%5C%29%5C+populations%5C+of%5C+C.%5C+taliensis%2C%5C+which%5C+suggested%5C+that%5C+the%5C+genetic%5C+background%5C+of%5C+long%5C-lived%5C+woody%5C+plant%5C+was%5C+not%5C+easy%5C+to%5C+be%5C+changed%2C%5C+and%5C+there%5C+were%5C+moderate%5C+high%5C+gene%5C+flow%5C+between%5C+populations.%5C+However%2C%5C+there%5C+was%5C+a%5C+significant%5C+difference%5C+%5C%28P%5C+%3C%5C+0.05%5C%29%5C+between%5C+wild%5C+%5C%28AR%5C+%3D%5C+5.9%5C%29%5C+and%5C+cultivated%5C+%5C%28AR%5C+%3D%5C+7.1%5C%29%5C+populations%5C+distributed%5C+in%5C+the%5C+same%5C+place%5C+in%5C+Yun%5C+county%2C%5C+Yunnan%5C+province%2C%5C+which%5C+may%5C+result%5C+from%5C+the%5C+hybridization%5C+and%5C+introgression%5C+of%5C+species%5C+in%5C+the%5C+tea%5C+garden%5C+and%5C+anthropogenic%5C+damages%5C+to%5C+the%5C+wild%5C+population.%5C+The%5C+hypothesis%5C+of%5C+hybrid%5C+origin%5C+of%5C+C.%5C+grandibracteata%5C+was%5C+tested%5C+by%5C+morphological%5C+and%5C+microsatellites%5C+analyses.%5C+Compared%5C+with%5C+other%5C+species%2C%5C+the%5C+locules%5C+in%5C+ovary%5C+of%5C+C.%5C+grandibracteata%5C+are%5C+variable%2C%5C+which%5C+showed%5C+a%5C+morphological%5C+intermediate%5C+and%5C+mosaic.%5C+Except%5C+one%5C+private%5C+allele%2C%5C+Ninety%5C-nine%5C+percent%5C+alleles%5C+of%5C+C.%5C+grandibracteata%5C+were%5C+shared%5C+with%5C+these%5C+of%5C+C.%5C+taliensis%5C+and%5C+C.%5C+sinensis%5C+var.%5C+assamica.%5C+And%5C+C.%5C+grandibracteata%5C+was%5C+nested%5C+in%5C+the%5

officinale is a valuable medicinal plants，mainly distributed in Yunnan, Guangxi and Anhui. It is necessary to understand the environmental adaptation for the effective acclimation and cultivation of this species. Up till now, there is little information on the ecophysiological adaptation of D. officinale, especially on the photosynthetic response to temperature. This paper investigated the response of photosynthesis and growth of D. officinale to temperature, and the stem polysaccharide content of D. officinale at different temperatures, in order to understand how growth temperature affect the growth and development of D. officinale and to determine the suitable temperature ranges and day-night temperature differences for the growth and development of D. officinale. The result are summarized as follows: 1. Temperature has a significant effect on the photosynthetic rate (Pn) of D. officinale, The light saturated photosynthesis at ambient CO2 concentration (Pmax) of the plants were highest at T-30/20. High photosynthetic rate at T-30/20 were related to a larger leaf area (LA) and the more balance between the maximum rate of electron transport and maximum rate of RuBP-mediated carboxylation. 2. Temperature also has a significant effect on the growth and polysaccharide content of D. officinale’s stem. The polysaccharide content of D. officinale at T-20/10 was significantly higher than at the other temperatures, but the stem length, stem node number, stem fresh weight and stem dry weight was the highest at T-30/20. 3. The utilization of solar energy were highest at T-30/15 temperature difference between day and night, it also has the highest content of chlorophyll, and respiration rate was lower, resulting in higher dry matter accumulation and accumulation of relatively higher polysaccharide content. 4. The polysaccharide content of D. officinale T-30/20 temperature difference between day and night was significantly higher than at the other temperatures, but the leaf area was smaller and chlorophyll content, stem length, node number, the average stem length, stem fresh weight and stem dry weight and other indicators are relatively low. 5. My thesis illuminated how temperature affect the growth and development of D. officinale. The suitable temperature ranges and day-night temperature differences for the growth of D. officinale are recommended as below: day temperature is 25℃ ~ 30 ℃, night temperature is 15℃ ~ 20℃, and day-night temperature difference should be maintained at 10℃ ~ 15℃.","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=LEAF%2BTEMPERATURES&order=desc&&fq=dc.project.title_filter%3ADendrobium%5C+officinale%5C+is%5C+a%5C+valuable%5C+medicinal%5C+plants%EF%BC%8Cmainly%5C+distributed%5C+in%5C+Yunnan%2C%5C+Guangxi%5C+and%5C+Anhui.%5C+It%5C+is%5C+necessary%5C+to%5C+understand%5C+the%5C+environmental%5C+adaptation%5C+for%5C+the%5C+effective%5C+acclimation%5C+and%5C+cultivation%5C+of%5C+this%5C+species.%5C+Up%5C+till%5C+now%2C%5C+there%5C+is%5C+little%5C+information%5C+on%5C+the%5C+ecophysiological%5C+adaptation%5C+of%5C+D.%5C+officinale%2C%5C+especially%5C+on%5C+the%5C+photosynthetic%5C+response%5C+to%5C+temperature.%5C+This%5C+paper%5C+investigated%5C+the%5C+response%5C+of%5C+photosynthesis%5C+and%5C+growth%5C+of%5C+D.%5C+officinale%5C+to%5C+temperature%2C%5C+and%5C+the%5C+stem%5C+polysaccharide%5C+content%5C+of%5C+D.%5C+officinale%5C+at%5C+different%5C+temperatures%2C%5C+in%5C+order%5C+to%5C+understand%5C+how%5C+growth%5C+temperature%5C+affect%5C+the%5C+growth%5C+and%5C+development%5C+of%5C+D.%5C+officinale%5C+and%5C+to%5C+determine%5C+the%5C+suitable%5C+temperature%5C+ranges%5C+and%5C+day%5C-night%5C+temperature%5C+differences%5C+for%5C+the%5C+growth%5C+and%5C+development%5C+of%5C+D.%5C+officinale.%5C+The%5C+result%5C+are%5C+summarized%5C+as%5C+follows%5C%3A%5C+1.%5C+Temperature%5C+has%5C+a%5C+significant%5C+effect%5C+on%5C+the%5C+photosynthetic%5C+rate%5C+%5C%28Pn%5C%29%5C+of%5C+D.%5C+officinale%2C%5C+The%5C+light%5C+saturated%5C+photosynthesis%5C+at%5C+ambient%5C+CO2%5C+concentration%5C+%5C%28Pmax%5C%29%5C+of%5C+the%5C+plants%5C+were%5C+highest%5C+at%5C+T%5C-30%5C%2F20.%5C+High%5C+photosynthetic%5C+rate%5C+at%5C+T%5C-30%5C%2F20%5C+were%5C+related%5C+to%5C+a%5C+larger%5C+leaf%5C+area%5C+%5C%28LA%5C%29%5C+and%5C+the%5C+more%5C+balance%5C+between%5C+the%5C+maximum%5C+rate%5C+of%5C+electron%5C+transport%5C+and%C2%A0maximum%5C+rate%5C+of%5C+RuBP%5C-mediated%5C+carboxylation.%5C+2.%5C+Temperature%5C+also%5C+has%5C+a%5C+significant%5C+effect%5C+on%5C+the%5C+growth%5C+and%5C+polysaccharide%5C+content%5C+of%5C+D.%5C+officinale%E2%80%99s%5C+stem.%5C+The%5C+polysaccharide%5C+content%5C+of%5C+D.%5C+officinale%5C+at%5C+T%5C-20%5C%2F10%5C+was%5C+significantly%5C+higher%5C+than%5C+at%5C+the%5C+other%5C+temperatures%2C%5C+but%5C+the%5C+stem%5C+length%2C%5C+stem%5C+node%5C+number%2C%5C+stem%5C+fresh%5C+weight%5C+and%5C+stem%5C+dry%5C+weight%5C+was%5C+the%5C+highest%5C+at%5C+T%5C-30%5C%2F20.%5C+3.%5C+The%5C+utilization%5C+of%5C+solar%5C+energy%5C+were%5C+highest%5C+at%5C+T%5C-30%5C%2F15%5C+temperature%5C+difference%5C+between%5C+day%5C+and%5C+night%2C%5C+it%5C+also%5C+has%5C+the%5C+highest%5C+content%5C+of%5C+chlorophyll%2C%5C+and%5C+respiration%5C+rate%5C+was%5C+lower%2C%5C+resulting%5C+in%5C+higher%5C+dry%5C+matter%5C+accumulation%5C+and%5C+accumulation%5C+of%5C+relatively%5C+higher%5C+polysaccharide%5C+content.%5C+4.%5C+The%5C+polysaccharide%5C+content%5C+of%5C+D.%5C+officinale%5C+T%5C-30%5C%2F20%5C+temperature%5C+difference%5C+between%5C+day%5C+and%5C+night%5C+was%5C+significantly%5C+higher%5C+than%5C+at%5C+the%5C+other%5C+temperatures%2C%5C+but%5C+the%5C+leaf%5C+area%5C+was%5C+smaller%5C+and%5C+chlorophyll%5C+content%2C%5C+stem%5C+length%2C%5C+node%5C+number%2C%5C+the%5C+average%5C+stem%5C+length%2C%5C+stem%5C+fresh%5C+weight%5C+and%5C+stem%5C+dry%5C+weight%5C+and%5C+other%5C+indicators%5C+are%5C+relatively%5C+low.%5C+5.%5C+My%5C+thesis%5C+illuminated%5C+how%5C+temperature%5C+affect%5C+the%5C+growth%5C+and%5C+development%5C+of%5C+D.%5C+officinale.%5C+The%5C+suitable%5C+temperature%5C+ranges%5C+and%5C+day%5C-night%5C+temperature%5C+differences%5C+for%5C+the%5C+growth%5C+of%5C+D.%5C+officinale%5C+are%5C+recommended%5C+as%5C+below%5C%3A%5C+day%5C+temperature%5C+is%5C+25%E2%84%83%5C+%5C%7E%5C+30%5C+%E2%84%83%2C%5C+night%5C+temperature%5C+is%5C+15%E2%84%83%5C+%5C%7E%5C+20%E2%84%83%2C%5C+and%5C+day%5C-night%5C+temperature%5C+difference%5C+should%5C+be%5C+maintained%5C+at%5C+10%E2%84%83%5C+%5C%7E%5C+15%E2%84%83."},{"jsname":"ECOLPIN[AGL2011-24296]","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=LEAF%2BTEMPERATURES&order=desc&&fq=dc.project.title_filter%3AECOLPIN%5C%5BAGL2011%5C-24296%5C%5D"},{"jsname":"EU

stresses could limit plant growth, development and propagation. Abiotic stress refers to the negative impact factors to the plants, such as extreme temperature, drought, flood, salinity, irradiation, chemicals and so on. To understand the mechanism of abiotic stress is very important.Membrane is the most sensitive organs in the cell that response to environmental changes. Cells respond and transduct environmental signals by changing content of membrane lipids and membrane proteins. The activity change of membrane phospholipase D (PLD) and the composition and content of membrane lipid molecules is one of the most anti-stress methods for the plants. It was reported that plants responded to some abiotic stresses such as freezing, thawing, seed aging and dehydration through changing lipid molecules especially the messenger phosphatidic acid (PA) and mutants of PLD were more tolerant to those stresses. It is important to investigate the characteristics and variation of membrane lipids and membrane proteins to understand the streee in plants.Three different kinds of stresses, including alpine scree temperature stress, allelopathy and Gamma irradiation stress, were studied in the present dissertation. And try to understand how plants response to those stresses by changing membrane system and the function of PLD in resistant to those stresses, lipidomic methods were used to profiling the changing of 11 lipids classes (160 lipids molecules) under thoses stresses. Moreover, PLD mutants were also used to study the role of PLD under those stresses. The mechanisms of plants response to stresses were very complicated; PLD and lipid molecules were not the only factors that response to stresses, the metabolism and phytohormones of tested plants under these stresses were also studied.In alpine scree of northwest Yunnan, the temperature was various from 33 °C during the midday to 4 °C at night, and the highest temperature could reach to 35 to 40 °C. Saussurea medusa and Solms-Laubachia linearifolia, which live in this environment, were chosen as studied model. The results showed that membrane lipid of these two plants significantly fluctuated with the temperature, while the double bond index (DBI) that had close relationship to temperature did not change. Furthermore, the the lysolipids which rise significantly under stresses did not change too much either. Laboratory mimic experiments also confermed the characteristics of lipids change to temperature in alpine scree plants. The results suggested that the plants living in such temperature changeable environment had already adapted to this situation and their membrane responded to the temperature was a kind of adaptation instead of stress response.Since the first introduction in Yunnan province of China in 1940s, E. adenophorum has spread very rapidly especially in southwestern China. Without understanding its invasive mechanism, it is impossible to control it. o-Hydroxycinnamic acid (o-HCA), an allelochmeical isolated from leachates of aerial parts of E. adenophorum were studied. o-HCA was abundant in aerial parts of E. adenophorum (1g/10kg fresh weight). The data showed that o-HCA not only had strong allelopathic effect on Arabidopsis seeds germination, but also inhibited seedling growth, and even induced root death of Arabidopsis seedlings. It could be proposed that o-HCA affected seedlings indirectly, through inducing root cell death, and it disturbed the water and ion absorption of plants and finally induced seedling to die. Interestingly, o-HCA could also inhibit E. adenophorum seed germination, while it showed no effect on its seedling growth. E. adenophorum can produce thousands of seeds and has the ability to vegetative reproduction, with which may alleviate the harmful effect of o-HCA on E. adenophorum. Unlike E. adenophorum, its neighbors’ population was inhibited, under this situation, E. adenophorum coule have better condition to live and invade successfully.Arabidopsis were irradiated with gamma rays, and 50-100 Gy gamma irradiation could inhibit seedling growth, and with the dosage above 200 Gy it could inhibit seedling flowering. Treated Arabidopsis wild types and their PLD a and d mutant with gamma ray showed no significant differences among them. The lipid molecules changes of seedlings under stress of gamma ray were also tested, and found that Gamama ray induced lipids degradation, among which, MGDG and DGDG degraded dramatically, while the average carbons in lipids did not changed. The lipids content (nmol per mg dry weight) decreased significantly, while the mol% content (mol% of total) changed slightly. Gamma irradiation also leaded to dramatically change of Arabidopsis seedling metabolomics and the phytohormones (ABA，ZR，JA，IAA).","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=LEAF%2BTEMPERATURES&order=desc&&fq=dc.project.title_filter%3AEnvironmental%5C+stresses%5C+could%5C+limit%5C+plant%5C+growth%2C%5C+development%5C+and%5C+propagation.%5C+Abiotic%5C+stress%5C+refers%5C+to%5C+the%5C+negative%5C+impact%5C+factors%5C+to%5C+the%5C+plants%2C%5C+such%5C+as%5C+extreme%5C+temperature%2C%5C+drought%2C%5C+flood%2C%5C+salinity%2C%5C+irradiation%2C%5C+chemicals%5C+and%5C+so%5C+on.%5C+To%5C+understand%5C+the%5C+mechanism%5C+of%5C+abiotic%5C+stress%5C+is%5C+very%5C+important.Membrane%5C+is%5C+the%5C+most%5C+sensitive%5C+organs%5C+in%5C+the%5C+cell%5C+that%5C+response%5C+to%5C+environmental%5C+changes.%5C+Cells%5C+respond%5C+and%5C+transduct%5C+environmental%5C+signals%5C+by%5C+changing%5C+content%5C+of%5C+membrane%5C+lipids%5C+and%5C+membrane%5C+proteins.%5C+The%5C+activity%5C+change%5C+of%5C+membrane%5C+phospholipase%5C+D%5C+%5C%28PLD%5C%29%5C+and%5C+the%5C+composition%5C+and%5C+content%5C+of%5C+membrane%5C+lipid%5C+molecules%5C+is%5C+one%5C+of%5C+the%5C+most%5C+anti%5C-stress%5C+methods%5C+for%5C+the%5C+plants.%5C+It%5C+was%5C+reported%5C+that%5C+plants%5C+responded%5C+to%5C+some%5C+abiotic%5C+stresses%5C+such%5C+as%5C+freezing%2C%5C+thawing%2C%5C+seed%5C+aging%5C+and%5C+dehydration%5C+through%5C+changing%5C+lipid%5C+molecules%5C+especially%5C+the%5C+messenger%5C+phosphatidic%5C+acid%5C+%5C%28PA%5C%29%5C+and%5C+mutants%5C+of%5C+PLD%5C+were%5C+more%5C+tolerant%5C+to%5C+those%5C+stresses.%5C+It%5C+is%5C+important%5C+to%5C+investigate%5C+the%5C+characteristics%5C+and%5C+variation%5C+of%5C+membrane%5C+lipids%5C+and%5C+membrane%5C+proteins%5C+to%5C+understand%5C+the%5C+streee%5C+in%5C+plants.Three%5C+different%5C+kinds%5C+of%5C+stresses%2C%5C+including%5C+alpine%5C+scree%5C+temperature%5C+stress%2C%5C+allelopathy%5C+and%5C+Gamma%5C+irradiation%5C+stress%2C%5C+were%5C+studied%5C+in%5C+the%5C+present%5C+dissertation.%5C+And%5C+try%5C+to%5C+understand%5C+how%5C+plants%5C+response%5C+to%5C+those%5C+stresses%5C+by%5C+changing%5C+membrane%5C+system%5C+and%5C+the%5C+function%5C+of%5C+PLD%5C+in%5C+resistant%5C+to%5C+those%5C+stresses%2C%5C+lipidomic%5C+methods%5C+were%5C+used%5C+to%5C+profiling%5C+the%5C+changing%5C+of%5C+11%5C+lipids%5C+classes%5C+%5C%28160%5C+lipids%5C+molecules%5C%29%5C+under%5C+thoses%5C+stresses.%5C+Moreover%2C%5C+PLD%5C+mutants%5C+were%5C+also%5C+used%5C+to%5C+study%5C+the%5C+role%5C+of%5C+PLD%5C+under%5C+those%5C+stresses.%5C+The%5C+mechanisms%5C+of%5C+plants%5C+response%5C+to%5C+stresses%5C+were%5C+very%5C+complicated%5C%3B%5C+PLD%5C+and%5C+lipid%5C+molecules%5C+were%5C+not%5C+the%5C+only%5C+factors%5C+that%5C+response%5C+to%5C+stresses%2C%5C+the%5C+metabolism%5C+and%5C+phytohormones%5C+of%5C+tested%5C+plants%5C+under%5C+these%5C+stresses%5C+were%5C+also%5C+studied.In%5C+alpine%5C+scree%5C+of%5C+northwest%5C+Yunnan%2C%5C+the%5C+temperature%5C+was%5C+various%5C+from%5C+33%5C+%C2%B0C%5C+during%5C+the%5C+midday%5C+to%5C+4%5C+%C2%B0C%5C+at%5C+night%2C%5C+and%5C+the%5C+highest%5C+temperature%5C+could%5C+reach%5C+to%5C+35%5C+to%5C+40%5C+%C2%B0C.%5C+Saussurea%5C+medusa%5C+and%5C+Solms%5C-Laubachia%5C+linearifolia%2C%5C+which%5C+live%5C+in%5C+this%5C+environment%2C%5C+were%5C+chosen%5C+as%5C+studied%5C+model.%5C+The%5C+results%5C+showed%5C+that%5C+membrane%5C+lipid%5C+of%5C+these%5C+two%5C+plants%5C+significantly%5C+fluctuated%5C+with%5C+the%5C+temperature%2C%5C+while%5C+the%5C+double%5C+bond%5C+index%5C+%5C%28DBI%5C%29%5C+that%5C+had%5C+close%5C+relationship%5C+to%5C+temperature%5C+did%5C+not%5C+change.%5C+Furthermore%2C%5C+the%5C+the%5C+lysolipids%5C+which%5C+rise%5C+significantly%5C+under%5C+stresses%5C+did%5C+not%5C+change%5C+too%5C+much%5C+either.%5C+Laboratory%5C+mimic%5C+experiments%5C+also%5C+confermed%5C+the%5C+characteristics%5C+of%5C+lipids%5C+change%5C+to%5C+temperature%5C+in%5C+alpine%5C+scree%5C+plants.%5C+The%5C+results%5C+suggested%5C+that%5C+the%5C+plants%5C+living%5C+in%5C+such%5C+temperature%5C+changeable%5C+environment%5C+had%5C+already%5C+adapted%5C+to%5C+this%5C+situation%5C+and%5C+their%5C+membrane%5C+responded%5C+to%5C+the%5C+temperature%5C+was%5C+a%5C+kind%5C+of%5C+adaptation%5C+instead%5C+of%5C+stress%5C+response.Since%5C+the%5C+first%5C+introduction%5C+in%5C+Yunnan%5C+province%5C+of%5C+China%5C+in%5C+1940s%2C%5C+E.%5C+adenophorum%5C+has%5C+spread%5C+very%5C+rapidly%5C+especially%5C+in%5C+southwestern%5C+China.%5C+Without%5C+understanding%5C+its%5C+invasive%5C+mechanism%2C%5C+it%5C+is%5C+impossible%5C+to%5C+control%5C+it.%5C+o%5C-Hydroxycinnamic%5C+acid%5C+%5C%28o%5C-HCA%5C%29%2C%5C+an%5C+allelochmeical%5C+isolated%5C+from%5C+leachates%5C+of%5C+aerial%5C+parts%5C+of%5C+E.%5C+adenophorum%5C+were%5C+studied.%5C+o%5C-HCA%5C+was%5C+abundant%5C+in%5C+aerial%5C+parts%5C+of%5C+E.%5C+adenophorum%5C+%5C%281g%5C%2F10kg%5C+fresh%5C+weight%5C%29.%5C+The%5C+data%5C+showed%5C+that%5C+o%5C-HCA%5C+not%5C+only%5C+had%5C+
