Phenotype of the tt4-1 es1-D double mutant. A and B, tt4-1 (A) and tt4-1 es1-D (B) flowers. Note the tt4-1 es1-D larger organ size. C, tt4-1 es1-D plant showing the characteristic zigzag pattern as seen in the es1-D stem. D, tt4-1 and tt4-1 es1-D fruits. Note the characteristic phenotype from es1-D, in which fruits are wider and shorter than tt4-1 fruits. E, Seeds from Col-0 and single and double mutants, showing the additive phenotype present in the tt4-1 es1-D double mutant. Bars = 0.2 mm in A and B; 2 cm in C; 0.2 cm in D; and 1 mm in E.
