Local auxin distribution in the aberrant phenotypes of MDEs of B. napus derived from the “mild” heat treatment. a Three-celled callus-like structures consisting of loose cells with any polarity in the DR5 activity. The position of the basal cell (bc) remarkably marked dehiscent exine. b Mushroom-like embryo phenotype with the DR5 activity in a structure resembles “foot” of mushroom (arrow). The blue color shows the expression of the reporter gus gene under control of the DR5 promoter. Bar = 20 μm
