Abstract

The chloroplast (cp) genome sequence of Bruguiera gymnorrhiza was characterized. The cp genome length was 163,795 bp in length, with a GC content of 35.3%, containing a large single copy (LSC) of 90,830 bp, a small single copy (SSC) of 20,207 bp, and a pair of inverted repeats (IRs) of 26,379 bp. The genome contained 121 genes, including 84 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. A phylogenetic analysis using cp genomes of mangroves and ecologically associated species resolved B. gymnorrhiza in Bruguiera with B. sexangula var. rhynchopetala. This complete chloroplast sequence offers a promising tool for further species identification and evolutionary studies of Bruguiera, as well as for mangroves.
