Abstract
The complete chloroplast sequence of Alocasia macrorrhizos is 154 995 bp in length, containing a pair of inverted repeats of 25 944 bp separated by a large single-copy (LSC) region and a small single-copy (SSC) region of 87 366 bp and 15 741 bp, respectively. The chloroplast genome encodes 132 predicted functional genes, including 87 protein-coding genes, four ribosomal RNA genes, and 37 transfer RNA genes, 18 of which are duplicated in the inverted repeat regions. In these genes, 16 genes contained single intron and two genes comprising double introns. A maximum-likelihood phylogenetic analysis using complete chloroplast genome revealed that A. macrorrhizos does not belong to Araceae family, which infers that the A. macrorrhizos is distant from the species in Araceae family.
