Characterization of the complete chloroplast genome sequence of Koelreuteria bipinnata

Abstract

Koelreuteria bipinnata is an important ornamental tree with attractive flowers and fruits. In this study, we used next-generation sequencing technology to obtain the complete chloroplast genome of K. bipinnata. The entire genome was determined to be 163,863 bp in size, harboring a typical quadripartite structure with a large single copy (LSC) region of 90,240 bp, a small single copy (SSC) region of 18,883 bp, and a pair of 27,370 bp inverted repeat (IR) regions. The genome was predicted to contain 132 genes, including 84 protein-coding genes, 40 tRNA genes, and 8 rRNA genes. The overall GC content of K. bipinnata chloroplast genome was 37.29%. Phylogenetic analysis based on complete chloroplast genome sequences indicated that K. bipinnata was closely related to K. paniculate. This study would be useful for future population genetics studies and phylogenetic analysis of K. bipinnata.
