The complete chloroplast genome of the white-berry yew Pseudotaxus chienii (Cupressales: Taxaceae), a rare and endangered relict plant endemic to southern China

Abstract

The white-berry yew (Pseudotaxus chienii) is a rare relict conifer endemic to southern China. Here, we assembled its chloroplast genome using Illumina sequencing technology. The circular genome is 126,925 bp long with an asymmetric base composition. It encodes a total of 115 genes, including 82 protein-coding genes (PCGs), 30 tRNAs and three rRNAs. Gene duplication was detected for a couple of tRNA genes. Nine genes have a single intron, and another gene possesses a couple of introns. Phylogenetic analysis suggested that P. chienii is closely related to three taxa of the genus Taxus (T. baccata, T. mairei, and T. wallichiana).
