The complete chloroplast genomes of Heterotis rotundifolia and Heterocentron elegans (Melastomataceae).

Heterotis and Heterocentron are two shrub genera in the tribe Melastomateae (Melastomataceae). Heterotis rotundifolia (Hr) and Heterocentron elegans (He) are both widely used as ornamental plants in the tropical regions. In this study, the complete chloroplast (cp) genomes of Hr and He were sequenced, assembled, and annotated. The cp genome sizes of Hr and He are 156,336 bp and 156,514 bp, respectively. The cp genome of Hr contains a total of 132 genes, including 87 protein-coding, 37 tRNA, and eight rRNA genes, while that of He has 131 genes, including 87 protein-coding, 36 tRNA, and eight rRNA genes. Phylogenetic analysis reveals that Hr is sister to Osbeckia stellata, while He is sister to Tibouchina longifolia.
