The complete chloroplast genome sequence of Blastus pauciflorus (Melastomataceae)

Abstract

Blastus pauciflorus, a shrub endemic to Hong Kong and Guangdong, south China, growing on low-altitude hillsides, under the forest. The species is controversial in classification. Herein, we report the complete chloroplast genome sequence assembled from Illumina pair-end sequencing data, with aims to resolve its relationship with the related species. The complete chloroplast genome was 155,983 bp in length, includes two inverted repeat regions (IRs) of 26,716 bp each, which were separated by a large single copy region (LSC) 86,101 bp and a small single copy region (SSC) 16,450 bp. The chloroplast genome contained 129 genes, including 82 protein-coding genes, 2 pseudogenes, 37 tRNA genes and 8 rRNA genes. The overall GC content in the chloroplast genome of B. pauciflorus was 37.0%. Phylogenetic analysis showed that B. pauciflorus is closed to B. cochinchinensis.
