Complete chloroplast genome of Baccaurea ramiflora (phyllanthaceae), a promising underutilized species

Abstract

Baccaurea ramiflora is a high economic value for the exploitation and utilization of wild fruit tree species with edible and medicinal values in Southeast Asia. In this study, the complete chloroplast genome sequence of B. ramiflora was assembled and characterized. The chloroplast genome was 161,089 bp in length, consisting of a large single copy (LSC) of 89,515 bp and a small single copy (SSC) region of 18,826 bp, which were separated by a pair of 26,374 bp inverted repeat (IR) regions. The overall GC content was 36.71%. A total of 132 genes, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes were identified. A low intraspecies variation within B. ramiflora was found with 22 single nucleotide polymorphisms (SNPs) and 17 insertions and deletions (INDELs). Phylogenetic tree reconstructed by 14 chloroplast genomes revealed that B. ramiflora clusters together with species of Phyllanthus, Glochidion, and Flueggea.
