Characterization of the complete chloroplast genome of Amorphophallus konjac (Araceae) and its phylogenetic analysis

Abstract

The whole chloroplast genome of Amorphophallus konjac is determined in this study. The genome size was 161,647 bp in length, containing a large single copy region of 90k bp and a small single copy region of 20k bp, which were separated by a pair of 25,722 bp inverted repeat regions. The complete chloroplast genome contained 131 genes, including 86 coding-protein (79 PCG species), 8 rRNA (4 rRNA species), and 37 tRNA genes (30 tRNA species). Based on the phylogenetic analysis, the genus Amorphophallus, represented by A. konjac might show a close relationship with Pinellia and Colocasia by the limited data for current. These complete chloroplast genomes of A. konjac laid a good foundation for population genomics, molecular, and ecological studies of Amorphophallus.
