Characterization of the complete chloroplast genome of Camellia brevistyla, an oil-rich and evergreen shrub

Abstract

Camellia brevistyla is an economic species for its seeds with high oil content and ornamental value, which is cultivated widespreadly across southern China. In this study, the complete chloroplast (cp) genome sequence of C. brevistyla was assembled and annotated in order to future genetic research. The whole cp genome of C. brevistyla is 159,281 bp in size, composed of a small single copy (SSC) region of 15,662 bp and a large single copy (LSC) region of 86,251 bp separated by a pair of inverted repeats (IRs, IRA: 130598: 159281, IRB: 86252: 114935). The overall GC content of C. brevistyla cp genome is 37.19%, with the base content A (31.03%), T (31.78%), C (18.94%), and G (18.25%). Phylogenetic analysis of 20 species based on 74 protein-coding genes shows that C. brevistyla is evolutionarily closest to Camellia danzaiensis.
