Fig. 9. Leaf phenotypes of jag nub mutants. (A-D) Fourth or fifth leaves from wild-type (A), jag (B) and jag nub (C,D) mutants. (C) Arrowheads point to notches in a jag nub leaf. (E) In jag nub mutants, leaves often develop radial outgrowth (enations, white arrowhead) on the abaxial side. These enations often develop near the tips of leaves and serrations. (F,G) SEM images of an enation emerging from the abaxial mid-vein of a jag nub leaf. Scale bars: 2 mm for A-D; 1 mm for E.
