The complete chloroplast genome of Dipelta yunnanensis (Caprifoliaceae), a vulnerable plant in China

Abstract

Dipelta yunnanensis (Caprifoliaceae) is a medicinal plant endemic to China. It has been included in the Chinese Species Red List and is also listed as a vulnerable species in the IUCN Red List. In this study, we determined the complete chloroplast (cp) genome sequence of Dipelta yunnanensis using Illumina paired-end sequencing. The whole cp genome was 155,359 bp in length, consisting of a pair of inverted repeat regions of 23,397 bp, a small single-copy region of 19,098 bp, and a large single-copy region of 89,467 bp. The genome encoded 128 unique genes including 82 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall GC content of the genome was 38.4%. Phylogenetic analysis with the reported chloroplast genomes of Dipsacales revealed that D. yunnanensis had a close relationship with Kolkwitzia amabilis. The chloroplast genome sequence of D. yunnanensis offers a useful resource for future conservation genetics and phylogenetic studies.
