The complete chloroplast genome of Torreya nucifera (Taxaceae) and phylogenetic analysis

Torreya nucifera (L.) Siebold & Zucc. (Taxaceae) is a tertiary relict tree species with a distribution that is limited to South Korea and Japan. In the present study, the complete chloroplast (cp) genome of T. nucifera was sequenced and analyzed. The genome was 136,985 bp in length and contained 118 genes, including 82 protein-coding genes, 33 tRNA genes, and 4 rRNA genes. Fifteen of the genes contained a single intron, whereas ycf3 contained two introns and there were no inverted repeat sequences in the genome. Phylogenetic analysis supported the monophyly of Torreya species within the Taxaceae and T. nucifera was closely related to its congener T. grandis.
