Complete plastome sequence of Wrightia laevis Hook. f. a dyestuff species

Abstract

Wrightia laevis Hook. f. is a great tree of Apocynaceae. It is mainly distributed in Southeast provinces of China and Southeast Asian countries. It is a plant that combines dyestuff and economic value. There is no study on the genome of W. laevisso far. Here we report and characterize the complete plastid genome sequence of W. laevis in order to provide genomic resources useful for promoting its conservation. The complete chloroplast genome of W. laevis is 155,274 bp in length with a typical quadripartite structure, consisting of a large single-copy region (LSC, 85,463 bp), a single-copy region (SSC, 18,181 bp) and a pair of inverted repeats (IRs, 25,815 bp). There are 133 genes annotated, including 88 unique protein-coding genes, 8 unique ribosomal RNA genes, and 37 transfer RNA genes. The overall G/C content in the plastome of W. laevis is 38.05%. The complete plastome sequence of W. laevis will provide a useful resource for the conservation genetics of this species as well as for phylogenetic studies in Apocynaceae.
