High Levels of Genetic Diversity within One Population of Rheum tanguti- cum on the Qinghai-Tibet Plateau have Implications for Germplasm Conservation
Rheum tanguticum, a source plant for the traditional Chinese medicine Dahuang (rhubarb), is an endangered species. In this study, we first assessed genetic diversity using 102 internal transcribed spacer (ITS) sequences cloned from one population of R. tanguticum on the Qinghai-Tibet Plateau. In total, 1773 polymorphic sites were identified, including 707 sites in the ITS1 region, 773 sites in ...
متن کاملRAPD analysis of genetic diversity and population structure of Elymus sibiricus (Poaceae) native to the southeastern Qinghai-Tibet Plateau, China.
Genetic diversity of Elymus sibiricus (Poaceae) was examined in eight populations from the southeast Qinghai-Tibet Plateau. We detected 291 RAPD polymorphic loci in 93 samples. The percentage of polymorphic bands (PPB) was 79%. Genetic diversity (H(E)) was 0.264, effective number of alleles (N(E)) was 1.444, Shannon's information index (H(O)) was 0.398, and expected Bayesian heterozygosi...
متن کاملGenetic diversity and population structure of Rheum tanguticum (Dahuang) in China
BACKGROUND Wild Rheum tanguticum (Dahuang in Chinese) has becoming endangered in China. This study aims to examine the genetic structure and genetic diversity of R. tanguticum within species, and the genetic differentiation within and among populations in China. METHODS The variability and structure of 19 populations of R. tanguticum were investigated by their chloroplast DNA matK sequences. ...
متن کاملInformation System of the Wetlands on the Qinghai-tibet Plateau
This study establishes an information system of the wetlands and lakes on the Qinghai-Tibet Plateau. We sort up on the wetlands and use Visual Basic 6.0 for the management and development of MapObjects, and the ArcSDE pattern to place the spatial and attribute data into the Microsoft SQL Server relational integrated database. We demonstrate how this Wetland Information System, containing all th...
متن کاملActinobacterial Diversity in the Sediments of Five Cold Springs on the Qinghai-Tibet Plateau
The actinobacterial diversity was investigated in the sediments of five cold springs in Wuli region on the Qinghai-Tibet Plateau using 16S rRNA gene phylogenetic analysis. The actinobacterial communities of the studied cold springs were diverse and the obtained actinobacterial operational taxonomic units were classified into 12 actinobacterial orders (e.g., Acidimicrobiales, Corynebacteriales, ...
