Characterization of the complete chloroplast genome of mangrove Rhizophora apiculata Blume (Rhizophoraceae)

The chloroplast (cp) genome sequence of Rhizophora apiculata was characterized. The cp genome length was 164,343 bp in length, containing a typical structure of a large single copy (LSC) of 93,155 bp, a small single copy (SSC) of 19,376 bp, and two inverted repeats (IRs) of 25,906 bp, with a GC content of 34.9%. There were 131 genes were annotated in the cp genome, including 85 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. A phylogenetic analysis using cp genomes of mangroves and ecologically associated species resolved R. apiculata in Rhizophora with R. stylosa and R. x lamarckii. This complete chloroplast sequence offers a promising tool for further species identification and evolutionary studies of Rhizophora, as well as for mangroves.
