Figure 1. Mutations in the SCA1 gene alter leaf morphology and pigmentation.

(A–G,I,J) Rosettes from the (A) Ler, (D) Col-0, and (G) No-0 wild types, the (B) sca1-1, (E) sca1-2, (F) sca1-1/sca1-2, (I) sca1-1/sca1-3, and (J) sca1-2/sca1-3 mutants, and (C) the sca1-1 35S_pro:SCA1 transgenic line. (H) Dissected silique from a SCA1/sca1-3 plant showing a sca1-3/sca1-3 aborted seed. Unless otherwise stated, all plants are homozygous for the mutations shown. Pictures were taken (A–G,I,J) 16 and (H) 40 days after stratification (das). Scale bars indicate (A-G, I, J) 2  mm, and (H) 0.2  mm.
