Mitochondrial DNA A DNA Mapp Seq Anal. 2016 Sep;27(5):3512-3. doi: 10.3109/19401736.2015.1074195. Epub 2015 Aug 14.

Abstract

The complete chloroplast genome sequence of Torreya fargesii (Taxaceae), a relic plant endemic to China, is presented in this study. The genome is 137 075 bp in length, with 35.47% average GC content. One copy of the large inverted repeats is lost from this genome. The T. fargesii chloroplast genome encodes 118 unique genes, in which trnI-CAU, trnQ-UUG, trnN-GUU are duplicated. Protein-coding, tRNA and rRNA genes represent 54.7%, 1.9% and 3.4% of the genome, respectively. There are 17 intron-containing genes, of which 6 are tRNA genes. A maximum likelihood phylogenetic analysis revealed a strong sister relationship between Torreya and Amentotaxus.

Keywords: Chloroplast genome; Taxaceae; Torreya fargesii; phylogenetic relationship.
