Abstract
Balakata baccata belongs to the family Euphorbiaceae and is distributed in Yunnan province, China, and other southeast Asian countries, e.g., Bangladesh, Cambodia, India, Indonesia, etc. Here, we report and characterize the complete plastome of B. baccata. The complete plastome is 163,988 bp in length and contains a typical quadripartite structure and gene content found in angiosperms, including two inverted repeat (IR) regions of 27,274 bp, a large single-copy (LSC) region of 90,946 bp and a small single-copy (SSC) region of 18,494 bp. The plastome contains 129 genes, consisting of 84 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall G/C content in the plastome of B. baccata is 35.6%. Phylogenetic results show that B. baccata is the earliest diverging lineage of Euphorbioideae. Euphorbia helioscopia + E. esula, E. tirucalli + E. milii and B. baccata have a closer phylogenetic relationship than other taxa within Euphorbiaceae. The complete plastome sequence of B. baccata will provide a useful resource for the conservation genetics of this species as well as for phylogenetic studies in Euphorbiaceae.
