The complete chloroplast genome of <i>Torreya nucifera</i> (Taxaceae) and phylogenetic analysis

Abstract

<i>Torreya nucifera</i> (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 <i>T</i>. <i>nucifera</i> 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 <i>ycf3</i> contained two introns and there were no inverted repeat sequences in the genome. Phylogenetic analysis supported the monophyly of <i>Torreya</i> species within the Taxaceae and <i>T</i>. <i>nucifera</i> was closely related to its congener <i>T</i>. <i>grandis</i>.
