LEAFY (abbreviated LFY) is a plant gene that causes groups of undifferentiated cells called meristems to develop into flowers instead of leaves with associated shoots.[1]

LEAFY is involved in floral meristem identity.

LEAFY, which encodes a plant-specific transcription factor, is found in all land plants and one of its exons have been used extensively in phylogenetic work on spermatophytes.[2] When the gene is overexpressed, the plant is less sensitive to environmental signals and flowers earlier.[3]
