Abstract

We, at first, fully characterized the complete chloroplast genome of the woody bamboo Acidosasa gigantea using genome skimming and focused on comparative analyses among Acidosasa and Indosasa. This newly sequenced chloroplast genome (GenBank NO. MN917206) is a typical circular structure with 139,711 bp in length and comprises of an 83,295 bp large single-copy (LSC) region, a 12,824 bp small single-copy (SSC) region, and a pair of 21,796 bp inverted repeats (IRs). The GC content of A. gigantea is 38.9% and the sequences contained 132 unique genes were successfully annotated, including 39 tRNA genes, 8 rRNA genes, and 85 protein-coding genes. Phylogenetic analysis shows that A. gigantea is highly clustered in the Arundinaria clade (clade VI) of Arundinarieae, a sister of the clade of Acidosasa purpurea and was not clustered on the same branch as Indosasa sinica. Therefore, it is more accurate to classify A. gigantea into Acidosasa.

Keywords: Arundinarieae; Acidosasa gigantea; chloroplast genome; genome skimming; phylogenetic relationship.
