Complete chloroplast genome of Baccaurea ramiflora and its phylogenetic analysis

Abstract

Baccaurea ramiflora Lour. is a popular tropical fruit tree, mainly grown in Myanmar, India, and other tropical or sub-tropical regions where it is commonly referred to as Myanmar grapes, Burmese grapes, or Latkan, respectively. Besides food, B. ramiflora is a traditional medicinal plant with several pharmaceutical effects. It is also a crucial component of Chinese Dai medicine. Here, the chloroplast genome of B. ramiflora was sequenced, assembled, and annotated. The complete chloroplast genome is 161,093 bp in length with a GC content of 36.71%. Additionally, it comprises a large single-copy region (LSC) of 89,503 bp, a small single-copy region (SSC) of 18,818 bp, and two inverted repeat regions (IRa and IRb) of 26,386 bp. In total, 128 genes were annotated, including 82 protein-coding genes, 37 tRNA genes, 8 rRNA genes, and 1 pseudogene. Phylogenetic analysis revealed that B. ramiflora is closely related to Phyllanthus emblica, Glochidion chodoense, and Phyllanthus amarus. This study provides useful genomic information for future phylogenetic studies of B. ramiflora and Phyllanthaceae family.
