LFY — Brassica oleracea

Summary

BoLFY, encoded by gene BOLC102_C03P069600.1 on cabbage chromosome 3, is a member of the FLO/LFY family of transcription factors, containing a floricaula/leafy C-terminal domain and a SAM domain. The protein localises to the nucleus and cytosol, binds DNA and chromatin, and exhibits ATP-dependent chromatin remodeller activity, ubiquitin-protein transferase activity, and transcription factor binding. BoLFY is associated with the regulation of flower development, inflorescence meristem identity, meristem maintenance and structural organisation, root meristem growth, vegetative growth, gibberellin and jasmonic acid signalling, miRNA processing, and defence responses to fungi. It has been linked to numerous agronomic traits including flower, carpel, petal, stamen and gynoecium morphology, axillary bud and leaf traits, whole plant size, seed yield, yield, vegetative-to-reproductive phase transition, boron sensitivity, bacterial disease response, seed dormancy, stomatal opening, and auxin content. Related genes in other species are associated with floral organ patterning, flower morphogenesis, and responses to salt and drought stress.
