Observed phenotypes after inducing sectors by heat shock. (a–f) Plants carrying (a) emb1408, (b) emb1586, (c) emb1637 and (d,e) emb2001 mutations. (g,h) Control plants carrying the HS
pro:Cre and pCB1-Gateway constructs, but not an emb mutation. (e) Pale-green plants with impaired growth. (f) Intense GFP fluorescence in one of the plants shown in (e). Scale bars represent (a–e, g,h) 2 mm, and (f) 50 µm.
