LFY — Brassica oleracea var. botrytis

Summary

BoLFY, encoded by the gene BOLND125_C03P061520.1_BOLND125_V1 on cauliflower chromosome 3, is a member of the FLO/LFY family of transcription factors. It possesses DNA-binding, chromatin-binding, and ATP-dependent chromatin remodeler activities, and is localized to the nucleus and cytosol. In cauliflower, BoLFY is associated with the regulation of meristem identity, inflorescence and flower development, bract morphogenesis, organ boundary specification, and the vegetative-to-reproductive phase transition. It has been linked to numerous agronomically important traits, including yield, seed yield, flower morphology, leaf number and size, plant size, vegetative growth time, seed dormancy, and responses to biotic stress and boron sensitivity. Studies of related genes in other species connect the family to floral organ patterning, flower morphogenesis, and responses to drought and salt stress.
