The complete chloroplast genome of Camellia grijsii, an ornamental shrub with floral aroma

Abstract

Camellia grijsii is an ornamental shrub with a floral aroma, which is widely cultivated and used for landscaping in China. To obtain the genetic information of C. grijsii, we have sequenced and assembled the complete chloroplast (cp) genome based on the Illumina Hiseq platform. The total genome size is 161,078 bp in length with 37.18% GC, which contains a large single copy (LSC, 84,645 bp) region, a small single copy (SSC, 15,772 bp) region, and a pair of inverted repeat (IRs, 30,330 bp) regions. It is composed of 81 protein-coding genes, 4 ribosomal RNAs, and 43 transfer RNAs. The cp genome of C. grijsii has also been compared with other species of Camellia, and the results showed that the C. grijsii and the C. grandbibracteata are closely related. This study provides the complete cp genome of C. grijsii and has an important reference value for the evolutionary analysis.
