EDF1 — Triticum turgidum subsp. durum

Summary

TRITD1AV1G218480 (symbol EDF1, also known as TtEDF1) on durum wheat chromosome 1A encodes a protein with DNA-binding transcription factor activity, transcription corepressor activity, and calcium-dependent protein serine/threonine kinase activity. It is associated with the regulation of leaf morphogenesis, photoperiodism and flowering, gibberellic acid homeostasis, negative regulation of transcription by RNA polymerase II, and cellular responses to drought, carbon dioxide, and absence of light. The gene has been linked to seed yield, biomass yield, flowering time, disease tolerance, salt tolerance, stomatal opening and closure, transpiration rate, root thickness, leaf elongation rate, and seedling growth and development. It localizes to the nucleus, plastid, cytosol, cytoplasm, and plasmalemma. Studies of related genes in other species link the EDF1/RAV family to flowering time, salt and drought stress responses, and disease resistance.
