Characterization of the complete chloroplast genome of the Camellia nitidissima, an endangered and medicinally important tree species endemic to Southwest China.

ABSTRACT: The Camellia nitidissima is an endangered tree species native to Southwest China with high economic and medicinal values. Genetic information of C. nitidissima would provide good knowledge for the conservation of this wild resource. In this article, we characterized the complete chloroplast genome of C. nitidissima using Illumina sequencing technology. The size of circular genome is 157,247 bp, containing a large single copy (LSC) region of 86,880 bp and a small single copy (SSC) region of 18,258 bp. The LSC region and SSC region are separated by a pair of inverted repeat regions (IRa and IRb), each of 26,068 bp. In total, 136 genes are encoded in this cp genome, including 89 protein-coding genes (81 species), 39 tRNA genes (30 species), and 8 rRNA genes (4 species). The overall G + C content of the chloroplast genome is 37.3%. The phylogenetic analysis suggests that C. nitidissima is closely related to C. petelotti.
