Complete chloroplast genome sequence of Pueraria thomsonii, an important traditional Chinese medicine plant.

ABSTRACT: Pueraria thomsonii is a leguminous plant with high root yield and starch content. It is also a medicinal material in the Chinese pharmacopeia. However, the raw materials of P. thomsonii are often confused with some non-medicinal Pueraria plants. To enrich the genetic resources of P. thomsonii and guide its molecular identification, the complete chloroplast genome was sequenced and reported. The total genome of P. thomsonii is 153,434?bp in length. consisting of two inverted repeat regions (IR_S, 25,640?bp each) separated by a large single-copy (LSC, 84,155?bp) and a small single-copy region (SSC, 17,999?bp). The overall GC content is 35.41%. It contains 130 genes, including 85 protein coding genes, 8 rRNA genes and 37 tRNA genes. Phylogenetic analysis showed that P. thomsonii could be distinguished from other plants and closely related to the legume Pachyrhizus erosus. This study enriches the genetic information of P. thomsonii and contributes to the screening of excellent germplasm.
