Phenotypic characters in Arabidopsis of constitutive IsLFY1 and IsLFY2 expressions. Figures from a to d are related to transgenes that the genes were crossed into wild Arabidopsis plants. Four-week IsLFY1 transgenic line (a), wild Arabidopsis plants (b), and IsLFY2 transgenic line (c). The IsLFY1 and IsLFY2 transgenic plants did not differ significantly in appearance from the wild-type plant. Flowers for the transgenic plants were consistent with the wild plants (d). Figures from e to j are related to transgenes that the genes were crossed into lfy-1 mutants. lfy-1 mutant (e). IsLFY1 transgenic line (f). IsLFY2 transgenic line (g). The IsLFY1 and IsLFY2 were inactive to rescue the lfy mutants. The transgenic plants and lfy mutant consistently showed that the early flowers were replaced by bracts, which subtended secondary inflorescences (h). The later flowers consisted of sepals and carpels (i and j).
