The first complete plastome of Chimonobambusa quadrangularis (Fenzl) Makino: assembly, annotation and phylogenetic analysis

Abstract

Chimonobambusa quadrangularis (Fenzl) Makino is one of the ‘Square Bamboo’ due to its square-shaped culm. However, as an edible bamboo, there is no genomic information reported so far. In this study, we reported and characterized the first plastome of C. quadrangularis based on Illumina Hiseq sequencing. The plastome exhibited a typical angiosperm circular structure, containing four regions: large single-copy region (LSC: 83,125 bp), small single-copy region (SSC: 12,811 bp), and a pair of inverted repeat regions (IR: 21,802 bp). The plastome consisted of 139,540 bp in size, with 82 protein-coding genes, 39 tRNA genes, and eight rRNA genes. The total nucleotide composition consisted of 30.16% A, 30.97% T, 19.25% C, and 19.63% G. The G + C content of the whole plastome was 38.88%. Phylogenetic analysis based on the complete plastomes of six species indicated that C. quadrangularis was closed to C. hejiangensis. The plastome is helpful for studying the evolution of beneficial adaptations and developing bioremediation and biomedical science.
