0.05). For some populations, germination capacity in 12-h photoperiod was significantly higher than that in completed darkness（W-FD: P < 0.01, W-JD: P < 0.05）.Genetic variation within and among six populations was assessed using AFLP markers. Genetic diversity was higher at species level (PPL = 69.19%, HE = 0.221) than at population level (PPL = 26.22%, HE = 0.095, Is =0.140), and populations in southeast Yunnan were strongly differentiated from those in southwest Yunnan (Nei’s GST = 0.575; FST = 0.655). UPGMA analysis demonstrated a clear genetic division between the two populations from DeHong (SW Yunnan; D-JD and D-HG) and the four from WenShan (SE Yunnan; W-FD, W-LH, W-ML, and W-MG). Within-population genetic variation was significantly correlated with population isolation (r(PPL) = -0.94, P = 0.006; r(HE) = -0.85, P = 0.032; r(Is) = -0.87, P = 0.025), but not with population size (r(PPL) = 0.63, P = 0.178; r(HE) = 0.54, P = 0.268; r(Is) = 0.56, P =

study can reveal important biological features of plants and answers to a certain degree in phylogeny and distribution of genetic materials and so forth. By hard working of cytologists, chromosome data of plants have been increased to a great abundance, but yet disorderly distributed in different magazines, which made researches based on the whole chromosome data of one taxon rarely launched. Scientific databases have become increasingly indispensable as researching data growing daily. As Cytological studies are booming in China, in order to fill the absence of digital and statistical data of plant chromosome researches and chromosome atlas, we started to develop a Chinese Seed Plants Chromosome Database, aiming to construct a database and start to record published chromosome data of Chinese seed plants. Based on this database, we chose the part of gymnosperms and gave a discussion to the features of its chromosomes’ evolution and variation. Cytological experiments have been applied to some important phyto-groups for phylogeny research and germplasm identification.Part I: The Chinese Seed Plants Chromosome Database and Discussion on the features of Gymnosperms chromosomes，1 The Chinese Seed Plants Chromosome Database，The frame of database was constructed by Microsoft Access 2003. 19 items of data were included in, they are: Chinese and Latin names of family, genus and species; plant pictures, mitosis metaphase and karyotype figures; morphological characteristics and distributions of the plant; chromosome numbers and basic numbers; karyotype formula; karyotype description; origin of the plant material; literature and the source of photos. In this database, data can be checked and shared easily by extracted out in species sorted interface or family sorted interface. 120 species in 29 genera and 10 families of Gymnospers have been collected and input to the database. In Angiosperms, 61 species in 10 genera of family Magnoliaceae and 80 species in 3 genera of family Theaceae have been collected and input to the database.2 Discussion on the features of evolution and variation of Gymnosperms chromosomes，By data collection of the database, we analyzed chromosome features of the group Gymnosperm. Plants of Gymnosperm had been through a long historical evolution on earth, fossil records of which originated from the late Devonian period. Once an authoritative and major classification level in the plant kingdom, most Gymnosperms have been extinct unless conifers, cycads, Ginkgo and Getales. Three main features of Gymnosperm chromosomes are: relatively large chromosome, which can be recognized from figures in the database; constant chromosome numbers, in most families of Gymnosperm the basic chromosome number keeps a certain value; comparatively low variation, karyotype under family level differs a little. The variation of chromosomes in Gymnosperm is dominated by Robertsonian changes. Contrary to common variation type in Angiosperms, the variation from high unsymmetric karyotype to low unsymmetric karyotype was found in existence in Gymnosperm.Part II: cytology research on some important phyto-groups，3 Karyomorphology of three species in the order Huerteales and their phylogenetic implications，The karyomorphology of three species in Dipentodon (Dipentodontaceae), Perrottetia (Celastraceae), and Tapiscia (Tapisciaceae), namely Dipentodon sinicus, Perrottetia racemosa, and Tapiscia sinensis, was investigated in the study. Recent molecular research has discovered close relationships among these three genera, which has led to the establishment of the order Huerteales with Perrottetia being placed in Dipentodontaceae. Herein we report the chromosome numbers of D. sinicus and P. racemosa for the first time, and present their karyotype formulas as 2n = 34 = 22sm + 12st (D. sinicus), 2n = 20 = 11m + 9sm (P. racemosa), and 2n = 30 = 22m(2SAT) + 8sm (T. sinensis). Asymmetry of their karyotypes is categorized to be Type 3B in D. sinicus, Type 2A in P. racemosa, and Type 2A in T. sinensis. Each of the species shows special cytological features. Compared with Perrottetia, Dipentodon has a different basic chromosome number, a higher karyotype asymmetry, and different karyomorphology of its interphase nuclei, mitotic prophase, and metaphase. Thus, on the basis of these results, we have reservations regarding the suggestion of placing Dipentodon and Perrottetia together in the family Dipentodontaceae.4 Genomic analyses of intergeneric hybrids between Michelia crassipes and M. calcicola by GISH，Genomic in situ hybridization (GISH) is becoming the method of choice for identifying parental chromosomes in interspecific hybrids. Interspecific F1 hybrid between Michelia crassipes and M. calcicola, tow highly ornamental species in Michelia of Magnolicaceae, has been analized by double-colored GISH with its parents’ genome as the probe. Research gave the results that the chromosome number of the F1 hybrid is 2n=38 as the same of species in Michelia and other genera in Magnoliaceae, the basic chromosome is x=19, the karyotype formula is 2n=38=32m+6sm, and the asymmetry of karyotype is 1B type. Based on chromosome data of Michelia in our database, the karyotype of this genus is featured mostly by metacentric chromosomes and submetacentric chromosomes. In Mechelia, the variation range of submetacentric chromosomes is 4 to 18 and of the karyotype asymmetry is 1A to 2B type. Both the karyotype and karyotype asymmetry type of F1 hybrid is among the variation range of Michelia. The figure of GISH showed that all the 38 chromosomes of F1 hybrid have crossing parental signals, and signal on the no.1 and no.7 chromosome showed differences, which proved that both the parental genome have been transmitted to and recombinated in F1

Forty–one compounds, including ten new compounds were isolated, and the biogenetic pathways of them were proposed.Chapter 1: Study on Chemical Constituents of Neolamarckia cadamba, Thirty–seven compounds were isolated from the leaves of the Neolamarckia cadamba, and thirty–three of them were identified, including ten new compounds. The structural types of these compounds are mainly monoterpenoid indole alkaloids. Among them, compounds 1, 2, 3, 4 and 5 are considered to be derived biogenetically from the corresponding glycosidic indole alkaloids by introducing the third nitrogen atom into their E ring respectively by the double Mannich–like condensation.

Hong, Phtheirospermum Bunge ex Fischer & C.A. Meyer, and Pseudobartsia D.Y. Hong, which is endemic to Eastern Asia. Based on chloroplast and nuclear sequences, we explored their phylogeny relationships within Orobanchaceae, the species relations within Pterygiella, and fruit and seed morphology of traditional tribe Rhinantheae. The phylogeny of “Pterygiella complex” was reconstructed based on nuclear and chloroplast sequences within the family Orobanchaceae. The genera relationship within the complex was reconstructed based on chloroplast sequences of atpB-rbcL, atpH-I, psbA-trnH, rpl16, trnL-F and trnS-G. The results showed that “Pterygiella complex” was not a natural group and could be divided into two different clades. Clade I included most taxa, e.g. Pterygiella, Xizangia, Pseudobartsia, Phtheirospermum (exclude P. japonicum). The species of this clade were endemic to East-Himalaya and Hengduan Mountains region. Clade II included Phtheirospermum japonicum (Thunberg) Kanitz, which was a heterogeneous member in genus Phtheirospermum and should be treated as a new monotypic genus. The results supported that Pterygiella bartschioides Hand.-Mazz. and Phtheirospermum glandulosum Benth. should be elevated to genus level as Xizangia and Pseudobartsia, respectively.Furthermore, we focused on the genus Pterygiella to explore the species’ circumscription by molecular phylogeny, DNA barcodes and morphological studies. The results suggested that Pterygiella should divide into three clades. P. duclouxii was divided into clade I and clade II, and P. nigrescens was included the clade I of these P. duclouxii taxa, with which it shares eglandular hairs on the stem. Clade III included P. suffruticosa and P. cylindrica, while the level of inter- and intra-species variation in two species did not support their distinction. Therefore, P. suffruticosa should move into or considered as a variety of P. cylindrica. The form of stem, leaf veins and the indumentum of stems are key traits for circumscribing the species within the genus. By comparing the effectiveness with core DNA barcodes, ITS-2 can be used as suitable DNA barcode in the genus Pterygiella.Fruit and seed characteristics of 49 species in 21 genera of the tribe Rhinantheae and 9 species in 9 genera of Orobachaceae were examined. 25 characters were selected and analyzed by principal component analysis for discovering the systematic significances. The results suggested four main types and six subtypes were distinguished based on gross seed coat appearance, inner tangential wall and thickenings of radial wall. Fruit and seed data reflect the close relationships within “Pterygiella complex”. While, Xizangia was distinctly different from Pterygiella. Phtheirospermum tenuisectum was more similar to the member of section minutisepala within the genus Phtheiroseprmum. Phtheirospermum japonicum was heterogeneous within the genus Phtheirospermum. On the whole, fruit and seed data supported Xizangia and Pseudobartsia as a genus rank and Phtheirospermum japonicum was a heterogeneous member in

China is well-known in the world for its richness in medicinal plant diversity and use knowledge. Some of the plant resources are developed industrially, while the others maintain the traditional use still. However, the extended resources utilization has caused the dramatic increase in demand and the exhaustion of resources. Thus, it is become one of the most important research topics that how to use medicinal resources rationally without resource depletion and those studies need to be supported by knowledge, information and data of related disciplines. On the bassis of authoritative books, literature searches and field survey, we constructed an herbal information database as an approach for data managing. Along the theme that how medicinal resources (plant species) used in various medicinal systems (traditional Chinese medicine, folk medicine), we developed a database integrating species information, herbal knowledge and usage information of about 10,000 medicinal plants, which have satisfied the data requirement of our study and analysis. In addition, we will shear data for research and decision-making by online database service. Finally, to verify the supporting function of this database in study and decision-making, and to explore new research methods of plant resources sustainable use, we applied research methods used in social statistics, such as logistic regression analysis, discriminant analysis and correspondence analysis. In addition, statistics and the analysis of typical medical systems were developed for studies on the resource usage and its sustainability factors. The data analysis showed as following: (1) Studies about plant resources sustainable utilization needs to be supported by integrated data of related subjects.(2) Applications of traditional medicines increased steadily. There was a substantial increase of Chinese patent medicines documented in each editions of pharmacopoeia, involving about 600-800 species of medicinal plant resources. But the modernization and development of medicinal plant resources have caused the resources depletion and cultivation. And there is a trend that the caltivation supplies the rescources demand (3) Whether plant resource will be depleted or not, is affected by the distribution of plant population, the rehabilitation ability of plants, the damage of human harvesting, and the advance in herb cultivation.(4) There is a considerable proportion of an unreasonable development pattern that cultivation is promoted by resource depletion. Two main reasons caused the exhaustion: lacking investigation in the supply abilities of wild plants and legging of wild species domestication. It is unwise to follow the existing developmental pattern, which will cause more resource depletion and biodiversity damage. Finally, on the basis of our study, we have proposed some reasonable strategies to avoid irrational factors in the herbal resources exploitation: Ø Develop traditional medicines furtherly for new medicinal resources.

Jiaozi from Yunnan is located in the eastern of the Central Yunnan Plateau, falling between the Pudu river and the Xiaojiang river, between the Jinshajiang river to the north and the Zhuanlong town of Luquan county to the south. It stands in the boundary of the Sino-Himalayan forest subkingdom and the Sino-Japan forest subkingdom, so it has a significant status, dew to the heterogeneous geographical environment and the sharp elevation drop in addition. Through field survey, specimens collection and identification and literatures consultion, we have obtained a brief list of Mt. Jiaozi, about 1517 species in 141 families and 531 genera, including varieties and subspices, among of which, there are 23 species in 7 families and 12 genera of gymnosperm. Based on statistic analysis, we get some conclusions as below. 1. As a type locality for many species, with various biodiversity and as much as endemism and some endangered plants, the flora of Mt. Jiaozi is viewed as a key area which should be paid special attention to. The flora constitution of this area has complex origins and multiple elements through the statistics. 2. The modern flora of Mt. jiaozi mainly includes the Chinese endemic elements and the Asian endemic elements, these two parts take up 81.65%. The characteristic of this flora is typically temperate. 3. Mt. Jiaozi is the north or the south distribution limitation to some important species as a floristic node. For example, species as Ephedra likiangensis, Solms-Laubachia pulcherrima, Soroseris hirsute, Paraquilegia microphylla which were used to be throught as limited in the northwestern of Yunnan had been found in this area. It indicates that, Mt. Jiaozi should become one of the foci of the flora regionalization in Yunnan, even in China. 4. In the view of the endemism of 6 families and 66 genera and 544 species in East Asian, this eara is a part of the East Asiatic Kingdom. The status of the flora of Mt. jiaozi in the East Asiatic Kingdom should be classified as Central Yunnan plateau subregion--Yunnan plateau region--Sino-Himalayan forest subkingdom.","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=OFFICINALIS&order=desc&&fq=dc.project.title_filter%3AMt.%5C+Jiaozi%5C+from%5C+Yunnan%5C+is%5C+located%5C+in%5C+the%5C+eastern%5C+of%5C+the%5C+Central%5C+Yunnan%5C+Plateau%2C%5C+falling%5C+between%5C+the%5C+Pudu%5C+river%5C+and%5C+the%5C+Xiaojiang%5C+river%2C%5C+between%5C+the%5C+Jinshajiang%5C+river%5C+to%5C+the%5C+north%5C+and%5C+the%5C+Zhuanlong%5C+town%5C+of%5C+Luquan%5C+county%5C+to%5C+the%5C+south.%5C+It%5C+stands%5C+in%5C+the%5C+boundary%5C+of%5C+the%5C+Sino%5C-Himalayan%5C+forest%5C+subkingdom%5C+and%5C+the%5C+Sino%5C-Japan%5C+forest%5C+subkingdom%2C%5C+so%5C+it%5C+has%5C+a%5C+significant%5C+status%2C%5C+dew%5C+to%5C+the%5C+heterogeneous%5C+geographical%5C+environment%5C+and%5C+the%5C+sharp%5C+elevation%5C+drop%5C+in%5C+addition.%5C+Through%5C+field%5C+survey%2C%5C+specimens%5C+collection%5C+and%5C+identification%5C+and%5C+literatures%5C+consultion%2C%5C+we%5C+have%5C+obtained%5C+a%5C+brief%5C+list%5C+of%5C+Mt.%5C+Jiaozi%2C%5C+about%5C+1517%5C+species%5C+in%5C+141%5C+families%5C+and%5C+531%5C+genera%2C%5C+including%5C+varieties%5C+and%5C+subspices%2C%5C+among%5C+of%5C+which%2C%5C+there%5C+are%5C+23%5C+species%5C+in%5C+7%5C+families%5C+and%5C+12%5C+genera%5C+of%5C+gymnosperm.%5C+Based%5C+on%5C+statistic%5C+analysis%2C%5C+we%5C+get%5C+some%5C+conclusions%5C+as%5C+below.%5C+1.%5C+As%5C+a%5C+type%5C+locality%5C+for%5C+many%5C+species%2C%5C+with%5C+various%5C+biodiversity%5C+and%5C+as%5C+much%5C+as%5C+endemism%5C+and%5C+some%5C+endangered%5C+plants%2C%5C+the%5C+flora%5C+of%5C+Mt.%5C+Jiaozi%5C+is%5C+viewed%5C+as%5C+a%5C+key%5C+area%5C+which%5C+should%5C+be%5C+paid%5C+special%5C+attention%5C+to.%5C+The%5C+flora%5C+constitution%5C+of%5C+this%5C+area%5C+has%5C+complex%5C+origins%5C+and%5C+multiple%5C+elements%5C+through%5C+the%5C+statistics.%5C+2.%5C+The%5C+modern%5C+flora%5C+of%5C+Mt.%5C+jiaozi%5C+mainly%5C+includes%5C+the%5C+Chinese%5C+endemic%5C+elements%5C+and%5C+the%5C+Asian%5C+endemic%5C+elements%2C%5C+these%5C+two%5C+parts%5C+take%5C+up%5C+81.65%25.%5C+The%5C+characteristic%5C+of%5C+this%5C+flora%5C+is%5C+typically%5C+temperate.%5C+3.%5C+Mt.%5C+Jiaozi%5C+is%5C+the%5C+north%5C+or%5C+the%5C+south%5C+distribution%5C+limitation%5C+to%5C+some%5C+important%5C+species%5C+as%5C+a%5C+floristic%5C+node.%5C+For%5C+example%2C%5C+species%5C+as%5C+Ephedra%5C+likiangensis%2C%5C+Solms%5C-Laubachia%5C+pulcherrima%2C%5C+Soroseris%5C+hirsute%2C%5C+Paraquilegia%5C+microphylla%5C+which%5C+were%5C+used%5C+to%5C+be%5C+throught%5C+as%5C+limited%5C+in%5C+the%5C+northwestern%5C+of%5C+Yunnan%5C+had%5C+been%5C+found%5C+in%5C+this%5C+area.%5C+It%5C+indicates%5C+that%2C%5C+Mt.%5C+Jiaozi%5C+should%5C+become%5C+one%5C+of%5C+the%5C+foci%5C+of%5C+the%5C+flora%5C+regionalization%5C+in%5C+Yunnan%2C%5C+even%5C+in%5C+China.%5C+4.%5C+In%5C+the%5C+view%5C+of%5C+the%5C+endemism%5C+of%5C+6%5C+families%5C+and%5C+66%5C+genera%5C+and%5C+544%5C+species%5C+in%5C+East%5C+Asian%2C%5C+this%5C+eara%5C+is%5C+a%5C+part%5C+of%5C+the%5C+East%5C+Asiatic%5C+Kingdom.%5C+The%5C+status%5C+of%5C+the%5C+flora%5C+of%5C+Mt.%5C+jiaozi%5C+in%5C+the%5C+East%5C+Asiatic%5C+Kingdom%5C+should%5C+be%5C+classified%5C+as%5C+Central%5C+Yunnan%5C+plateau%5C+subregion%5C-%5C-Yunnan%5C+plateau%5C+region%5C-%5C-Sino%5C-Himalayan%5C+forest%5C+subkingdom."},{"jsname":"Mushroom Research Foundation","jscount":"1","jsurl":"/simple-search?field1=all&rpp=10&accurate=false&advanced=false&sort_by=2&isNonaffiliated=false&search_type=-1&query1=OFFICINALIS&order=desc&&fq=dc.project.title_filter%3AMushroom%5C+Research%5C+Foundation"},{"jsname":"lastIndexed","jscount":"2024-05-24"}],"资助项目","dc.project.title_filter")'>
