Abstract

Camellia tetracocca H.T. Chang 1981 is an important wild relative of cultivated tea plants. Its leaves are widely used by local people to make tea, showing great economic and breeding values. We here report the complete chloroplast genome of C. tetracocca using Illumina sequencing technology. The complete chloroplast genome of C. tetracocca is 157,026 bp in length, and structurally contains a pair of inverted repeat regions (IRa and IRb, 26,052 bp) separated by a large single-copy region (LSC, 86,669 bp) and a small single-copy region (SSC, 18,253 bp). It is composed of 131 predicted genes, including 86 protein-coding genes, 37 transfer RNA genes, and eight ribosomal RNA genes. The overall GC content is 37.31%. Phylogenetic analysis among four Camellia species and 11 other close species reveals a close relationship between C. tetracocca and C. gymnogyna.

Keywords: Camellia tetracocca; chloroplast genome; phylogenetic analysis.
