Figure 3: Cyanogenesis differentiation between wild and cultivated cassava.
From: Cassava genome from a wild ancestor to cultivated varieties
(a) Minimizing of cyanogenic glucoside content in cultivar KU50 and Arg7 relative to wild W14: over twofold in leaves and fivefold in storage root with five repeat plants. (b) Differential expression of genes in the cyanogenic glucoside synthesis pathway between cultivar KU50, Arg7 and wild W14 identified by RNA-seq. DS, developing stem; ETR, early storage root; LF, leaf; LTR, late storage root; MTR, medium tuber root. (c) A transposon regulation model of cyanogenesis in cassava: among the interval regions of three genes in a linear array as CYP71E11, CYP71E7 and UGT85K4, there were more transposable or retrotransposable elements in the gene 1-kb upstream regions of cultivated species KU50 and AM560 than wild subspecies W14. CDS, Coding sequence.
