Genome skimming reveals the complete chloroplast genome of Ampelocalamus naibunensis (Poaceae: Bambusoideae: Arundinarieae) with phylogenomic implication.

Ampelocalamus naibunensis is one drooping bamboo with an important ornamental value endemic to Taiwan Island. To date, the genetic and genomic information of this species is little known. Here we characterized the complete chloroplast genome of A. naibunensis using genome skimming approach. The complete chloroplast genome is 139,860 bp, with a large single copy region (LSC) of 83,380 bp and a small single copy region (SSC) of 13,014 bp separated by a pair of inverted repeats (IRs) of 21,822 bp. The genome encodes a total of 129 genes, of which 111 are unique, containing 76 protein-coding genes, 4 ribosomal RNAs and 31 transfer RNAs. Sixteen distinct genes contain one or two introns, and the GC content of the cp genome is 38.9%. Phylogenomic analysis strongly supports the placement of A. naibunensis in the Chimonocalamus lineage (III), distantly related to A. calcareus (XI) within temperate woody bamboos.
