Complete Chloroplast Genome of Lespedeza maritima (Fabaceae), a Korean Endemic Shrub

초록

Lespedeza maritima Nakai (Fabaceae; Papilionoideae; Desmodieae) is a Korean endemic shrub, which grows in warm-temperate forests of mountain along southern-eastern coastal line. Although some phylogenetic studies of genus Lespedeza were conducted based on sequences of partial chloroplast region, each species was not monophyletic due to frequent hybridization and/or rapid diversification. Analysis using chloroplast genome could be helpful in this case, but there is no information. In the present study, we report complete chloroplast genome (cp genome) sequence of L. maritima, and it is first report of Lespedeza. The cp genome is 149,022bp in length, including a large single copy (LSC) region of 82,429 bp and a small single copy (SSC) region of 18.939 bp, and a pair of inverted repeats (IRs) of 23,827 bp that separated LSC and SSC. The degree of CG content is 35.0%, and this genome contains 134 unique genes, consisting of 72 protein-coding genes, 18 transcription/translation, 36 tRNAs and 8 rRNAs. Moreover, cp genome characteristics and its phylogenetic significance were also assessed within subtribe Lespedezinae by PCR screening and a genome phylogenetic tree.
