Vegetative Phenotypes of Wild-Type, pla2, and pla1 Plants.

(A) Seedlings at 2 weeks after germination. The lamina joint of the third leaf does not bend in pla2-1 and pla2-2, although they do bend in the wild type and pla1-4. Arrowheads indicate the lamina joints of the third leaf. Bar = 5 cm.

(B) Phenotype of the last vegetative leaf (flag leaf) of the wild type, pla2-1, and pla1-4 from left to right. Leaf size is reduced strongly in pla2-1 and pla1-4.

(C) Increase in the number of emerged leaves during development. Closed circles, open triangles, open diamonds, and open squares represent the wild type, pla2-1, pla2-2, and pla1-4, respectively. Bars indicate ± sd.
