Commelina communis is a hyperaccumulator on heavy metal with high drought resistance and endurance. Using Illumina next-generation sequencing data, its chloroplast genome is assembled and characterized. The complete chloroplast genome is 159,664 bp in length, consisting of a pair of inverted repeats (IRs) of 26,146 bp each, an 88,854 bp large single-copy (LSC) region and an 18,518 bp small single-copy (SSC) region. It has 137 genes in total, comprising 81 unique protein-coding genes, 32 unique tRNA genes, and 7 rRNA genes. Phylogenetic analysis based on the complete chloroplast genome sequences indicates that C. communis is sister to Belosynapsis ciliata among species with available chloroplast genome sequences.
Lophostemon confertus
(Myrtaceae), a fast-growing ornamental tree, is widely cultivated in tropical and subtropical regions. To determine its phylogenetic position within Myrtaceae, here we report its complete chloroplast (cp) genome, which is 160,297 bp long and contains two inverted repeats (IRs) of 26,490 bp each, separated by a small single-copy region of 18,826 bp and a large single-copy region of 88,491 bp. The cp genome contains 123 genes, including 73 unique protein-coding genes (six duplicated in the IR regions), 29 unique tRNA genes (seven duplicated in the IR regions), and four unique rRNA genes (all located in the IR regions). Phylogenetic analysis of 18 species of Myrtaceae showed that
L. confertus
is sister to
Xanthostemon chrysanthus.
The complete cp genome of
L. confertus
provides a valuable genetic resource for further phylogenetic studies.
Osbeckia stellata (Melastomataceae) is a shrub distributed in the South. Although many species of Osbeckia have important medicinal value, the phylogenetic position of Osbeckia within the family Melastomataceae remains unclear. Osbeckia stellata is one of the most widespread species in this genus. Here, we reported and characterized the complete chloroplast genome sequence of O. stellata assembled from Illumina sequencing reads. The chloroplast genome size is 156,372 bp, containing a large single copy (LSC) region of 85,741 bp, a short single copy (SSC) region of 17,115 bp, and a pair of inverted repeats (IRs) of 26,758 bp. We predicted a total of 136 genes consisting of 86 protein-coding genes, 48 tRNA genes, and 8 rRNA genes. Phylogenetic analysis showed that O. stellata was sister to Melastoma candidum.
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.
