LEAFY (LFY) is a DNA-binding transcription factor that regulates floral meristem identity. LFY is unusual among angiosperm developmental regulators because it is not part of an extended gene family. Recent expression studies and transgenic experiments have suggested that changes at the LFY locus might have played a role in the evolution of rosette flowering, a modified plant architecture that has evolved at least three times in Brassicaceae. Here we examined the sequences of LFY genes from 16… CONTINUE READING
