The complete chloroplast genome of Bauhinia racemosa Lam. (Fabaceae): a versatile tropical medicinal plant

Abstract

Bauhinia racemosa Lam. (1783), a versatile medicinal plant, belongs to the family Fabaceae (subfamily Cercidoideae). In this study, we analyzed the complete chloroplast genome to facilitate its use in genetic research. The complete chloroplast genome of B. racemosa was found to be 155,501 bp long, including two inverted repeat (IR) regions of 25,446 bp, which are separated by a small single-copy (SSC) region of 18,295 bp and a large single-copy (LSC) region of 86,314 bp. The overall GC content is 36.4%. The genome of B. racemosa contains 129 genes, including 83 protein-coding genes, 37 tRNAs, 8 rRNAs, and 1 pseudogene (rps19). Phylogenetic analysis suggests that B. racemosa forms a monophyletic clade with the other four Bauhinia species (B. brachycarpa, B. purpurea, B. blakeana and B. variegata var. variegata).
