Complete chloroplast genome of endangered Bruguiera hainesii C.G.Rogers 1919 and phylogenetic analysis with associated species

Bruguiera hainesii C.G.Rogers 1919, a true mangrove tree is seriously endangered in Vietnam. To detect evolutionary analysis between mangroves, we sequenced the complete chloroplast genome of B. hainesii using next-generation sequencing technology (Illumina Hiseq X Ten). Its genome was 164.305 bp in length, comprising 37% GC. The genome contained a large single-copy region of 91,724 bp, two inverted repeat regions of 52,720 bp, and a short single-copy region of 19,861 bp. Furthermore, it contained 130 genes, consisting of 83 protein-coding genes, 37 tRNAs, and 8 rRNAs. We detected 131 single-sequence repeats, including 119 mononucleotides, 11 dinucleotides, and one trinucleotide. Phylogenetic analysis showed strong support that B. hainesii was sister to B. cylindrica. The findings in this study provide a foundation for species identification, evolutionary genetics, and the conservation of endangered B. hainesii in Vietnam.
