The loss-of-function ant-1 allele reduces mature organ size and cell number. (A) Fully grown seventh-rosette leaves from an ant-1 mutant (Left) and wild-type plant (Right). (B) Width and length of mature rosette leaves and petals. Wild-type (n = 12) and ant-1 (n = 12) mature third-rosette leaves, and wild-type (n = 58) and ant-1 (n = 41) mature petals (stage 15) were analyzed. Bars on columns show SD. (C and D) Epidermal cells (×150) from the abaxial, distal portion of mature (stage 15) ant-1 (C) and wild-type petals (D).
