The complete chloroplast genome sequence of an conifer plant Torreya grandis (Pinales, Taxaceae)

Abstract

Chinese Nutmeg Tree ( Torreya grandis ) is a species of conifer in Taxaceae, which has a wide range in eastern and south-eastern China. Torreya grandis , endemic to eastern and south-eastern China, is a large tree, which own important economic value. Here, we report the complete chloroplast (cp) genome sequence and the cp genomic features of T. grandis . The genome was 136,949 bp long with 117 genes comprising of 82 protein-coding genes, 31 tRNA genes, and 4 rRNA genes. Phylogenetic analysis suggested that Torreya species formed a monophyletic clade within the Taxaceae family, and T. jackii is at the base of the tree and T. grandis and T. fargesii are sister groups of the inner clade.

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

“…The cp DNA of T. nucifera did not contain a pair of IRs separated by LSC and SSC regions, which is consistent with the cp genomes of other conifers (Miu et al. 2018 ; Ge et al. 2019 ).…”

The complete chloroplast genome of Torreya parvifolia, a species with extremely small population in China

“…The genome structure is similar to other Taxaceae species (Miu et al. 2018 ; Ge et al. 2019 ; Shin et al.…”
