Abstract

Torreya parvifolia (Torreya, Taxaceae) is endemic in Sichuan, China. It consisted of an extremely small population with less than 100 wild individuals. In this study, the complete chloroplast genome of T. parvifolia was assembled using the Illumina data. The complete chloroplast genome of T. parvifolia is 137,106 bp in length. The genome consists of 119 genes in total, including 82 protein-coding genes (PCGs), 4 ribosomal RNA (rRNA) genes, and 33 transfer RNA (tRNA) genes. Phylogenetic analysis indicated that T. parvifolia was closely related to T. fargesii, T. nucifera, and T. fargesii var. yunnanensis with strong support.

Keywords: Torreya parvifolia; chloroplast genome; phylogenetic analysis.
