Figure 5From: Transciptome analysis reveals flavonoid biosynthesis regulation and simple sequence repeats in yam (Dioscorea alata L.) tubersSimplified diagram depicting the flavonoid biosynthesis pathway in yam tubers. Gene abbreviations are listed in Table 3. 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.Back to article page
