      (a) Content of the D. elephantipes chloroplast genome[20]. (b) Phylogenetic tree of 48 Dioscorea species based on the concatenated matrix of matK, rbcL, tmL-F, psbA-tmH, rpl36-rps8, nad1, rps3 and 7 DNA[55].

    • Figure 3. 

      (a) Modeling the conversion between sucrose and starch during tuber amplification[34]. (b) Simplified diagram depicting the flavonoid biosynthesis pathway in yam tubers. Red arrows indicate genes that were significantly up-regulated in the purple-fleshed yam tuber. Gray indicates no change in gene expression between two tuber types[38]. (c) Putative mechanism of the PHH in D. dumetorum, blue represents GO annotation[41].

      Differences in the regulation of glycolysis during (S1) tuber sprouting, (S2) degraded tuber, (S3) new tuber formation and (S4) tuber maturation[44].
