Abstract:
Keteleeria hainanensis is an endemic species with extremely narrow distribution. In this study, the complete genome of K._hainanensis was sequenced and analyzed. The genome size is 117,366 bp and it contains two short inverted repeat regions of 1,272 bp, which was separated by a large single-copy (LSC) region of 74,819 bp and a small single-copy (SSC) region of 40,003 bp. The GC content of this genome was 38.57%. The chloroplast genome contained 103 unique genes, including 74 protein-coding gene, 25 tRNA genes, and 4 rRNA gene. Phylogenetic analysis base on 11 chloroplast genomes indicated that K. hainanensis is closely related to K. davidiana.
