The complete chloroplast genome of the Toxicodendron vernicifluum cv. Dahongpao, an elite natural triploid lacquer tree

Abstract

The Toxicodendron vernicifluum cv. Dahongpao is an elite natural triploid lacquer tree with high economic and medicinal value. Therefore, in this study, we first characterize T. vernicifluum cv. Dahongpao complete chloroplast (cp) genome sequence. The complete cp genome sequence of T. vernicifluum cv. Dahongpao, with 38.0% GC content, is 159,571 bp in length. The genome presents a typical quadripartite structure with two inverted repeat regions (each 26,511 bp in length), separated by one large single-copy region and one small single-copy region (87,475 and 19,074 bp in length, respectively). The overall GC content is 38%, while in the LSC, SSC, and IR regions the GC contents are 36.1%, 32.6%, and 43.0%, respectively. The cp genome encodes 131 functional genes, of which 114 genes are single-copy, including 80 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Phylogenetic analysis using maximum likelihood (ML) strongly support that T. vernicifluum cv. Dahongpao has a close phylogenetic relationship with Rhus chinensis and Pistacia weinmaniifolia.
