The complete chloroplast genome sequence of Citrus maxima (Burm.) Merr. ‘Guanximiyou’

Abstract

Citrus maxima (Burm.) Merr. ‘Guanximiyou’ is a major citrus tree largely cultivated in China. A previous study has reported the complete chloroplast genome of C. maxima, but there may be some differences between wild species and cultivating variety. In this study, the complete chloroplast genome sequence of ‘Guanximiyou’ pummelo was characterized using BGISEQ-500 sequencing. The chloroplast genome was 160,186 bp in length and separated into four distinct regions such as large single-copy region (87,939 bp), small single-copy region (18,395 bp), and a pair of inverted repeat regions (26,926 bp). The genome contained a total of 109 genes including 79 protein-coding genes, 29 tRNA genes, and 4 rRNA genes. Phylogenetic maximum-likelihood analysis revealed that ‘Guanximiyou’ pummelo was clustered with other Rutaceae species with high bootstrap values.
