Complete chloroplast genome of Vincetoxicum hainanense (Apocynaceae: Asclepiadoideae), an endangered liana endemic to China.

ABSTRACT: Vincetoxicum hainanense is an endangered liana species endemic to China. Habitat destruction coupled with difficulties in natural pollination has reduced its population size over time. As present studies have focussed more on breeding programmes instead of molecular aspects, here we reported on the complete chloroplast (cp) genome sequence of V. hainanense. The cp genome is 161,280?bp in size and includes two inverted repeat (IR) regions of 24,884?bp each, which is separated by a large-single copy (LSC) region of 92,084?bp and a small-single copy (SSC) region of 19,428?bp. A total of 131 genes were predicted, including 37 tRNA, 8 rRNA, and 86 protein-coding genes. Phylogenetic analysis showed that V. hainanense is clustered with other Apocynaceae species and sister to Biondia chinensis.
