Genetic 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 کاملMorphological Variation in Leaf Dissection of Rheum palmatum Complex (Polygonaceae)
AIMS Rheum palmatum complex comprises all taxa within section Palmata in the genus Rheum, including R. officinale, R. palmatum, R. tanguticum, R. tanguticum var. liupanshanense and R. laciniatum. The identification of the taxa in section Palmata is based primarily on the degree of leaf blade dissection and the shape of the lobes; however, difficulties in species identification may arise from th...
متن کاملKaryotype analysis of Rheum palmatum.
Rheum palmatum, one of the source plants of the traditional Chinese medicine rhubarb, is anendemic and endangered species. To our knowledge, this is the first report on the chromosome number and karyotype of this species. Sectioning combined with micrography was used to analyze the karyotype. The following results were obtained: R. palmatum had a stable chromosome number 2n = 22; the basic numb...
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 ...
متن کاملGenome-Scale Transcriptome Analysis of the Alpine “Glasshouse” Plant Rheum nobile (Polygonaceae) with Special Translucent Bracts
BACKGROUND Rheum nobile is an alpine plant with translucent bracts concealing the inflorescence which produce a "glasshouse" effect promoting the development of fertile pollen grains in such conditions. The current understanding of the adaptation of such bracts to alpine environments mainly focuses on the phenotypic and physiological changes while the genetic basis is very limited. By sequencin...
