ABSTRACTBaccaurea ramiflora cultivar Ha Chau is a specialty fruit in Can Tho City, Viet Nam, and exhibits a potential economic value. However, its genomic data have not been reported. In this study, we sequenced and characterized the complete chloroplast genome of B. ramiflora cultivar Ha Chau using the Illumina sequencing platform, which has a quadripartite structure, including a large single copy (LSC), a small single copy (SSC), and two inverted repeat (IR) regions. The size of the genome was 161,378 bp (made up of 36.7% GC content), which was composed of an 89,801 bp LSC (34.3% GC), an 18,833 bp SSC (30.8% GC), and two 26,372 bp IR (42.7% GC) regions. The newly sequenced chloroplast genome contained 79 protein‐coding genes, 30 tRNA genes, and four rRNA genes. Notably, the infA gene contained an internal stop codon whereas only rps16 exon2 remained in the complete chloroplast genome of B. ramiflora cultivar Ha Chau. Comparative genomic analyses indicated a high similarity of the chloroplast genome among B. ramiflora individuals regarding genome structure and gene content. However, B. ramiflora cultivar Ha Chau exhibited a lower pairwise identity in comparison with its counterparts. Further phylogenetic analysis also confirmed the sister relationship between B. ramiflora cultivar Ha Chau and other B. ramiflora individuals. This study provides initial genomic data for further studies examining evolutionary history, molecular markers, and genetic populations of B. ramiflora cultivar Ha Chau and its related species in Phyllanthaceae.
