Characterization of the chloroplast genome sequence of Bonia amplexicaulis (L.C.Chia, H.L.Fung & Y.L.Yang) N.H.Xia (Poaceae)

Abstract

Bonia amplexicaulis (L.C.Chia, H.L.Fung & Y.L.Yang) N.H.Xia is a member of the Bambusoideae subfamily in Poaceae. In this study, we sequenced, assembled and characterized the complete chloroplast genome of B. amplexicaulis. The complete chloroplast genome was 139,935 bp in size, including a large single copy region of 83,453 bp, a small single-copy region of 12,860 bp and a pair of reverse repeats of 21,811 bp in size. The annotation of the B. amplexicaulis chloroplast genome indicates that it contained 83 protein-coding genes, 36 tRNA genes and 8 rRNA genes. Our phylogenetic analysis of all protein-coding genes from the 36 complete chroloplast grass genomes using Cyperus rotundus as outgroup showed that B. amplexicaulis is closely related to Otatea glauca and Pariana campestris to form the Bambusoideae lineage of the grass family.
