Characterization of the complete chloroplast genome of Citrus hongheensis, a key protected wild plant in Yunnan province of China

Abstract

Citrus hongheensis is a key protected wild plant endemic to the Honghe river region in southeastern Yunnan, China. In the present study, its chloroplast genome was successfully assembled and annotated based on the Illumina Hiseq-2500 whole genome re-sequencing data. The chloroplast genome is 160,275 bp in size. Its large single copy region, small single copy region and inverted repeat region is 87,886 bp, 18,387 bp and 27,001 bp, respectively. Totally, 114 unique genes, including 80 protein-coding genes, 30 tRNAs and 4 rRNAs, were identified from the C. hongheensis chloroplast genome. According to the phylogenetic analysis result, the relationship between the chloroplast genome of C. hongheensis and C. maxima was found to be the closest.
