Fig. 2.

Exogenous SL can rescue the leaflet serration phenotype of SL-deficient mutants. GR24 was applied to the shoot tip at the indicated concentrations. (A, B) Scanned images of one representative leaflet in each condition. Representative leaflets with a solidity value equal to the average solidity of all leaflets in this condition were selected. Bar=5mm. (C) Illustration of solidity as a shape descriptor. The convex hull (black line) delimits the convex area of each leaflet. Solidity is calculated as the ratio of leaflet area/convex area. (D, E) Solidity values for leaflets of ccd8-1 and ccd7-1 mutants and their respective wild-type siblings, treated or not with GR24. Values correspond to the mean±SEM (n=49–85 leaflets for each condition). Different letters indicate statistically significant differences according to Mann-Whitney’s test (P<0.05 after Bonferroni adjustment). (This figure is available in colour at JXB online.)
