Abstract

Poncirus polyandra, a plant species with extremely small populations endemic to Fumin county of Yunnan province, has been classified as a national second-class protected wild plant. In this study, we assembled its complete chloroplast genome. The total genome size of P. polyandra was 160,211 bp in length, containing a large single-copy region of 87,406 bp, a small single-copy region of 18,771 bp, and a pair of inverted repeat regions of 27,017 bp. The all GC content of P. polyandra chloroplast genome was 38.4%. It contains 137 function genes, including 92 protein-coding genes, 37 tRNA genes, and eight rRNA ribosomal genes, 14 genes contain a single intron, and three genes have two introns. Phylogenetic analysis results strongly supported that P. polyandra was closely related to the genera of Citrus.
