Figure 4.

Phenotypes of wild-type, CLV3 (RNAi), and clv3–2 plants. Wild-type and CLV3 (RNAi) mutants are in the ecotype Wassilewskija, whereas clv3–2 is in the ecotype Landsberg erecta which has reduced internode elongation. The inflorescence meristems are enlarged in CLV3 (RNAi) (B) and clv3–2 (C) compared with wild type (A). (D) Wild-type flower. (E) CLV3 (RNAi) and (F) clv3–2 flowers have additional organs. (G–I) Cross section of gynoecia showing that the wild-type gynoecium (G) consists of two carpels, and gynoecia in CLV3 (RNAi) (H) and clv3–2 (I) have four carpels.
