Abstract

This study investigated the complete plastid genome of Phyllodium pulchellum, which represents the first report of the complete plastome for the genus Phyllodium in the tribe Desmodieae of the subfamily Papilionoideae. De novo assembly and annotation showed that the plastid genome is a typical quadripartite structure consisting of two inverted repeats (IR = 24,286 bp), one small single copy (SSC = 18,334 bp), and one large single copy (LSC = 82,715 bp). We found 111 unique genes, including 77 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Phylogenetic analysis based on the newly sequenced plastid genome of Ph. pulchellum and 11 plastomes obtained from GenBank recovered a strongly supported phylogenetic backbone of the tribe Desmodieae and a sister-relationship between Phyllodium and Ohwia.
