The complete chloroplast genome of agarwood producing species, Aquilaria sinensis (Lour.) Gilg: a species on IUCN red list

Abstract

The entire chloroplast genome of Aquilaria sinensis (Lour.) Gilg was identified as a circular molecule of 174,885 bp length with a typical tetrad structure, including a pair of inverted repeats (42,103 bp each), a large single copy (87,331 bp) and a small single copy (3,348 bp) regions. The A. sinensis cp genome encoded 8 rRNAs, 39 tRNAs, and 90 proteins. A phylogenetic tree was reconstructed using the 43 protein-coding genes of eight Thymelaeaceae. Two other Malvales, Abelmoschus esculentus and Durio zibethinus, were selected as the outgroup. Our phylogenetic analysis suggests that the five examined species of Aquilaria appeared a monophyletic group with robust support.
