Comparative plots of percent sequence identity of 18 chloroplast genomes in subfamily Zingiberoideae. The chloroplast genome of G. lancangensis was used as a reference genome (upper plot). The percentage of sequence identities were visualized in mVISTA software [34]. Gray arrows and thick black lines indicated gene orientation. Purple bars represented exons, sky-blue bars represented untranslated regions (UTRs), red bars represented non-coding sequences (CNS), gray bars represented mRNA and white regions represented sequence differences among all analyzed chloroplast genomes. The horizontal axis indicated the coordinates within the chloroplast genome. The vertical scale represented the identity percentage that ranged from 50 to 100%. The ten sequenced chloroplast genomes in this study were marked in bold
