LFY — Glycine max

Summary

GLYMA_04G202002V4 (GmLFY, also known as LFY3) encodes a member of the FLO/LFY family of transcription factors, characterized by a floricaula/leafy C-terminal domain and possessing chromatin DNA binding, sequence-specific DNA binding, and transcription cis-regulatory region binding activities, along with ATP-dependent chromatin remodeler and ubiquitin-protein transferase activities. In soybean, GmLFY is associated with leaflet and compound leaf morphogenesis, floral organ formation, maintenance of inflorescence meristem identity, regulation of vegetative growth, and meristem cell maintenance. The gene is linked to numerous traits including yield, seed yield, seed longevity, germination rate, leaflet number, stem thickness, flower and inflorescence morphology, plant size, vegetative growth time, and responses to biotic stress and boron sensitivity. Studies of related genes in other species connect the family to floral homeotic gene expression, flower morphogenesis, and floral organ patterning.
