Complete chloroplast genome of a Mangrove Natural Hybrid, Rhizophora × lamarckii

Abstract

Rhizophora × lamarckii is a natural hybrid of R. apiculata and R. stylosa, and it is also an endangered mangrove material in China with the exclusive location in Hainan Island. In this paper, we reported and characterized the complete chloroplast genome sequence of R. × lamarckii by assembling from short reads generated using Illumina sequencing. Total chloroplast genome size was 164,325 bp, including inverted repeats (IRs) of 26,325 bp, separated by a large single copy (LSC) and a small single copy (SSC) of 92,433 bp and 19,244 bp, respectively. A total of 121 genes, including 42 tRNAs, eight rRNAs, and 81 protein-coding genes, were identified. The GC content of R. × lamarckii is 34.67%. Phylogenetic analysis using the maximum likelihood algorithm showed that R. × lamarckii is sister to a clade with four species in the order Malpighiales.
