Complete chloroplast genome of an endangered plant, Hopea hainanensis

Abstract

Hopea hainanensis is an endangered species with scattered occurrence, and it is one of the representative species of tropical rainforest in Hainan Island. In this paper, we reported and characterized the complete chloroplast genome sequence of the species assembled from short reads generated by Illumina sequencing. Total chloroplast genome size was 151,795 bp, including inverted repeats (IRs) of 26,098 bp, separated by a large single copy (LSC) and a small single copy (SSC) of 84,419 bp and 19,520 bp, respectively. A total of 136 genes, including 45 tRNA, 8 rRNA, and 83 protein-coding genes, were identified. The GC content of H. hainanensis is 37.3%. Phylogenetic analysis using the maximum likelihood algorithm showed that H. hainanensis is sister to a clade with five species in the order Dicotyledoneae.
