The plant genus Melastoma of the family Melastomataceae is comprised of nine species and one variety in China. Melastoma dodecandrum is the only creeping species of this genus. Previous study has reported the complete chloroplast genome of M. dodecandrum from Guangzhou, China, but there may be some differences between plant populations from different regions. Herein, we reported the complete chloroplast genome of M. dodecandrum from Fuzhou, China, which was assembled from Pacbio and whole genome data was sequenced. The sequence has a circular molecular length of 156,598 bp and contained 129 genes. Phylogenetic analysis indicated that M. dodecandrum was closely related to M. candidum in Melastomataceae. The study aims to provide insights for the future studies on the differences in molecular evolution level between plant populations of M. dodecandrum and taxonomy of Melastoma.
ARTICLE HISTORY
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
