Figure 2. Illustration of the effect of w1 on flower and seed coat phenotypes. (A) Purple flower of plants with W1 genotype (left panel) or white flower of plants with w1 genotype (right panel) in lines L79-908 (W1,ii,R,T,Wp) and Williams (w1,ii,R,T,Wp) respectively, both of which have yellow seed coats because of silenced ii allele. (B) Seed coats of plants L83-930 with W1,i,r,t,Wp genotype (left panel) compared with seed coats of plants of the isoline L82-2669 with w1,i,r,t,Wp genotype (right panel). It shows little difference in color revealing the very small contribution delphinidins and prodelphinidins make to seed coat pigmentation.
