LFY — Arabidopsis thaliana

Summary

AT5G61850, known as LFY (LEAFY) in Arabidopsis thaliana, encodes a floricaula/leafy family transcription factor that binds sequence-specific DNA and chromatin, and possesses ATP-dependent chromatin remodeler activity. LFY is associated with the regulation of floral meristem identity and flower development, including bract morphogenesis, carpel formation, and the maintenance of inflorescence meristem identity. The gene is linked to numerous agronomically relevant traits such as yield, seed weight, harvest index, plant size, flowering time, and floral organ number. LFY is also associated with stress responses, including bacterial disease response and pathogen resistance, as well as nitrate transport and gibberellin biosynthesis. Related genes in other species link the family to shoot meristem development and spikelet number in rice.
