Fig. 3. Phenotypic effects of LFY:VP16 are dependent on endogenous LFY. Structures shown are ‘single flowers’ from a weak LFY:VP16 line. (A) In an otherwise wild-type background, the flowers of this line are similar to those of wild type. (B) In LFY:VP16 lfy-12, each flower consists only of congenitally fused carpels. (C,D) In LFY:VP16 lfy-12 /+ ag-1, single flowers are replaced by structures consisting of flower buds interspersed with floral organs. The first-whorl organs of the flower shown in C have fallen off; only secondary flowers remain. (E,F) In LFY:VP16 lfy-12 ag-1, only a small number of floral organs were produced before the floral meristem reverted to produce only floral buds. Scale bars 1 mm (A-C,F), and 3 mm (D,E).
