Characterization of the complete chloroplast genome of Carya hunanensis W. C. Cheng & R. H. Chang

Carya hunanensis W. C. Cheng & R. H. Chang is a tree of great economic importance in China. In this study, the complete chloroplast genome of C. hunanensis was determined and analyzed phylogenetically. The whole genome was determined to be 159,892 bp in length, presenting a typical quadripartite structure with a large single copy (LSC) region (89,466 bp), a small single copy (SSC) region (18,714 bp), and a pair of inverted repeat (IR) regions (25,856 bp each). There were 132 genes annotated in the genome, including 84 protein-coding genes, 40 tRNA genes, and eight rRNA genes. The overall GC content of C. hunanensis chloroplast genome was 36.24%. Phylogenetic analysis indicated that C. hunanensis was closely related to C. kweichowensis and Annamocarya sinensis.
