The complete chloroplast genome sequence of Camellia atrothea (Ericales: Theaceae)

Abstract

Camellia atrothea H.T. Chang, H.S. Wang & B.H. Chen 1983 is a native Camellia species in China, which has significant economic and breeding values. Here, we assembled and analyzed the complete chloroplast genome sequence of C. atrothea based on the whole genome sequencing data from Illumina NovaSeq6000 platform. Results show that the complete chloroplast genome of C. atrothea is 157,099 bp in length, and comprises a large single-copy (LSC, 86,643 bp) region, a small single-copy (SSC, 18,276 bp) region, and a pair of inverted repeats (IRs, 26,090 bp) region. Annotation of the C. atrothea chloroplast genome predicts a total of 133 genes, including 88 protein-coding genes, 8 ribosomal RNA genes, and 37 transfer RNA genes. The overall GC content accounts for 37.30% of the genome, which is clearly consistent with that of other previously published Camellia species from section Thea. Phylogenetic analyses of the whole chloroplast genome sequences of 14 Camellia species using Actinidia chinensis as outgroup reveals that C. atrothea has a close relationship with C. leptophylla.
