Characterization of the complete chloroplast genome of ‘Yunning No.1’ lemon (Citrus limon)

Abstract

‘Yunning No.1’ lemon, a mutant of Eureka lemon, is originally found in Yunnan province of China and is the main cultivated lemon variety there. In this study, we assembled and annotated its chloroplast genome using Illumina Hiseq-2500 whole genome re-sequencing data. Its chloroplast genome is 160,141 bp in size, containing a 87,754 bp large single copy region, a 18,385 bp small single copy region and a pair of 27,001 bp inverted repeat region. Like many citrus species, 114 unique genes (including 80 protein-coding genes, 30 tRNAs and 4 rRNAs) could be identified from the chloroplast genome of ‘Yunning No.1’. Phylogenetic analysis revealed that the ‘Yunning No.1’ chloroplast genome was closest to Citrus maxima.
