Complete chloroplast genomes of Camellia perpetua and Camellia indochinensis

Abstract

In this study, we report on the complete chloroplast genomes of Camellia perpetua and Camellia indochinensis for the first time. The complete chloroplast genome of C. perpetua is 156,804 bp in length and is comprised of two inverted repeat (IR) regions (25,996 bp each), a large single copy (LSC) region (86,570 bp), and a small single copy (SSC) region (18,242 bp). The chloroplast genome of C. perpetua harbors 86 protein-coding genes, 28 tRNA genes, and eight rRNA genes, with an overall GC content of 37.32%. The chloroplast genome of C. indochinensis showed similar characteristics as that of C. perpetua. The total length of C. indochinensis chloroplast genome is 156,571 bp, which includes 26,053 bp each of the two IR regions, 86,246 bp of the LSC region, and 18,219 bp of the SSC region. C. indochinensis chloroplast genome contains 85 protein-coding genes, 28 tRNA genes, and eight rRNA genes, with an overall GC content of 37.34%. Furthermore, a phylogenetic tree was constructed using the chloroplast genome sequences of the two species, and their phylogenetic positions were determined.
