First comparative analysis of complete chloroplast genomes among six Hedysarum (Fabaceae) species

Hedysarum is one of the largest genera in Fabaceae family, mainly distributed Northern Hemisphere. Despite numerous molecular studies on genus , there still a lack research aimed at defining specific characteristics chloroplast genome (cp genome) genus. Furthermore, interrelationships between sections based cp have not yet been studied. In this study, comprehensive analyses complete genomes six species, corresponding to Multicaulia and Stracheya were conducted. The H. drobovii flavescens lehmannianum sequenced for study. species showed high similarity with regard size (except taipeicum ), gene sequences, classes, as well lacking IR region. whole found contain 110 genes ranging from 121,176 bp 126,738 length, including 76 protein-coding genes, 4 rRNA 30 tRNA genes. addition, SSRs repetitive sequence regions reported each species. shared 7 common exhibited 14 unique SSRs. As well, three highly variable ( clpP, accD atpF ) Pi values detected among we conducted phylogenetic using legume seven results that form monophyletic clade closely related Onobrychis Alhagi . both our reconstructions section more than This study first work investigate which provides useful genetic information further genus, evolutionary studies, relationships, population genetics, identification.
