Fig. 2.

Effect of gain- and loss-of function of genes involved in valve margin formation. a SEM images of the bases of fruits at stage 17 from Arabidopsis wild type, 35S::FUL, ga4 and ind mutants. b SEM images and staining of cross sections are shown for the indicated Brassica species. Sections are from the middle of the fruits where the replum is narrower. Upper row displays images from wild-type fruits at stage 17, whereas stage 17 fruits from the indicated mutant genotypes are shown in the lower row. Scale bars correspond to 100 µm for A. thaliana SEMs and B. juncea and B. oleracea sections, 200 µm for B. rapa sections and 250 µm for B. juncea and B. rapa SEMs
