The complete chloroplast genome of Phyllanthus acidus (L.) Skeels (Phyllanthaceae)

Abstract

Phyllanthus acidus (L.) Skeels (Phyllanthaceae) is a potential medicinal plant recognized for its sour and tart tasted fruits. In this study, the chloroplast genome of P. acidus was sequenced, assembled, and characterized. The chloroplast genome size was 156,331 bp and the overall GC content was 36.9%. Additionally, the chloroplast genome had a quadripartite structure consisting of a large single copy (LSC; 85,807 bp in length; GC content: 34.6%), a small single copy (SSC; 19,262 bp in length; GC content: 30.6%), and two inverted repeat regions (IR; 25,631 bp in length; GC content: 43.1%). A total of 113 unique genes were annotated in the chloroplast genome, comprising 79 protein-coding genes, 30 tRNAs, and four rRNAs. The phylogenetic analysis based on 79 protein-coding genes revealed the paraphyly of the Phyllanthus genus. These findings provided additional genetic information for further research on P. acidus and the cp genome in the Phyllanthaceae family.
