Karyotype 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 کاملThe Organic Acids of Rhubarb (rheum Hybridum)*
“General pronouncements on the significance of the plant acids are at present probably of little value. . . The true significance of the acid metabolism of plants may perhaps lie close to Kostytchev’s later point of view that these acids are the building stones from which some of the complex plant products originate. . . The plant acids are possibly convertible into amino acids and proteins, co...
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 کاملA structure-based mechanism for benzalacetone synthase from Rheum palmatum.
Benzalacetone synthase (BAS), a plant-specific type III polyketide synthase (PKS), catalyzes a one-step decarboxylative condensation of malonyl-CoA and 4-coumaroyl-CoA to produce the diketide benzalacetone. We solved the crystal structures of both the wild-type and chalcone-producing I207L/L208F mutant of Rheum palmatum BAS at 1.8 A resolution. In addition, we solved the crystal structure of th...
