Development of Chloroplast Genomic Resources in Chinese Yam (Dioscorea polystachya)

Figure 2

The patterns of nucleotide substitution among the six D. polystachya chloroplast genomes. The patterns were divided into six types as indicated by the six non-strand-specific base-substitution types (i.e., numbers of considered G to A and C to T sites for each respective set of associated mutation types).
