Genetic variation in cultivated Rheum tanguticum populations
To examine whether cultivation reduced genetic variation in the important Chinese medicinal plant Rheum tanguticum, the levels and distribution of genetic variation were investigated using ISSR markers. Fifty-eight R. tanguticum individuals from five cultivated populations were studied. Thirteen primers were used and a total of 320 DNA bands were scored. High levels of genetic diversity were de...
متن کاملGenetic Variation in Rheum palmatum and Rheum tanguticum (Polygonaceae), Two Medicinally and Endemic Species in China Using ISSR Markers
AIMS Both Rheum palmatum and R. tanguticum are important but endangered medicinal plants endemic to China. In this study, we aimed to (i) investigate the level and pattern of genetic variability within/among populations of those species; (ii) evaluate genetic differentiation between both species and its relationships and ascertain whether both species are consistent with their current taxonomic...
متن کاملGenetic Variation in Natural and Cultivated Populations of Primula Veris
Primula veris, a well-known pharmaceutical plant, is a long-lived perennial protected by law in Poland, so its rhizomes and roots can be collected as pharmaceutical stock only from cultivation. Genetic variation of three natural P. veris populations numbering 500–1200 individuals and of three cultivated populations derived from seeds collected from natural sites was investigated in respect of t...
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 کاملOptimization of chloroplast microsatellite PCR conditions and primer screening for endangered Rheum officinale, Rheum palmatum, and Rheum tanguticum.
Chloroplast microsatellite primers were developed in order to provide more population genetic information of endangered Rheum officinale, R. palmatum, and R. tanguticum for conservation. The dried roots and rhizomes of these plants are important in traditional Chinese medicine. The results showed that the optimum concentrations of Mg(2+), Taq DNA polymerase, dNTPs, template DNA, and primers in ...
