Chloroplast genome structure and phylogenetic analysis of Juniperus chinensis

Abstract

The chloroplast genome of Juniperus chinensis L. was assembled and annotated in this research. The size of the chloroplast genome is 127,811 bp. It contains a 91,322 bp large single-copy region and a 35,960 bp small single-copy region; it does not contain inverted repeats. The genome encodes 82 protein-encoding genes, 33 tRNAs, and four rRNAs. Phylogenetic analysis showed that J. chinensis was closer to congeneric species than those of Cupressaceae. These results provide a genomic basis for further evolutionary research on conifers.
