The complete chloroplast genome sequence of Calystegia hederacea Wall. in Roxb. 1824 (Convolvulaceae) in Enshi, Hubei.

ABSTRACT

Calystegia hederacea Wall. in Roxb. 1824 is a perennial herbaceous vine in the family Convolvulaceae and has several biological effects. Herein, we reported the first complete chloroplast genome of C. hederacea. The chloroplast genome sequence was 152,057 bp in length, comparing a large single-copy (LSC) region of 87,891 bp, a small single-copy (SSC) region of 19,866 bp, and a pair of inverted repeat (IR) regions of 22,150 bp. This sequenced chloroplast genome contained 126 predicted genes, including 81 protein-coding genes, 37 tRNA genes, and eight rRNA genes, and the total GC content of the chloroplast genome was 37.79%. Phylogenetic analysis revealed that C. hederacea was closely related to C. soldanella. The chloroplast genome presented in this study will enrich the genome information of the genus Calystegia and provide deeper insights into the evolution study of the family Convolvulaceae.
