Characterization of the complete chloroplast genome of Taxus wallichiana as the medicinal plant from China

Abstract

Taxus wallichiana is a member of the family Taxaceae, which is a unique and endangered species in China and is widely used for ornamental, material and medicinal purposes. The complete chloroplast genome of T. wallichiana was found to possess a total size of 128,168 bp. The GC content of T. wallichiana chloroplast genome sequence is 37.3%, the overall nucleotide composition of chloroplast genome sequence is: A of 30.7%, T of 32.0%, C of 19.0% and G of 18.3%. The total of 116 genes were successfully annotated, which contained 83 protein-coding genes, 29 transfer RNA genes, and 4 ribosomal RNA genes. The ML phylogenetic analysis result showed that T. wallichiana was closely related to Taxus baccata in the phylogenetic relationship using the neighbour-joining (NJ) method in this study.
