The species of Oxytropis DC. of section Gloeocephala Bunge (Fabaceae) from Northeast Asia: genetic diversity and relationships based on sequencing of the intergenic spacers of cpDNA and ITS nrDNA.
Phylogenetic relationships within Oxytropis DC. sect. Gloeocephala Bunge from Northeast Asia were studied using plastid intergenic spacers (psbA-trnH + trnL-trnF + trnS-trnG) and ITS nrDNA. Populations of O. anadyrensis Vass., O. borealis DC., O. middendorffii Trautv., O. trautvetteri Meinsh., and O. vasskovskyi Jurtz. were monomorphic or characterised by a low level of chloroplast genetic diversity (h varied from 0.143 to 0.692, and π from 0.0001 to 0.0005). Presumably, the low genetic diversity was a result of the severe bottlenecks during Pleistocene glaciation-interglacial cycles. Twenty chlorotypes were identified; species studied had no shared chlorotypes. Chlorotypes of O. anadyrensis, O. borealis, and O. middendorffii formed two lineages each, while the chlorotypes of O. trautvetteri and O. vasskovskyi formed one separate lineage each in the phylogenetic network. There were specific diagnostic markers of cpDNA in each lineage, excluding O. vasskovskyi. The presence of a species-specific diagnostic marker in O. trautvetteri and specific markers in two lineages of O. anadyrensis support circumscribing these taxa as independent species. Regarding ITS nrDNA polymorphism, five ribotypes were detected. The differences revealed in plastid and nuclear genomes of Oxytropis sect. Gloeocephala confirmed that the Asian sector of Megaberingia was the main centre of diversification of arctic legumes.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
