BOA — Triticum turgidum subsp. durum

Summary

TRITD3BV1G277990, designated BOA (also known as TtBOA, TtPCL1, TtLUX, PCL1, LUX) on durum wheat chromosome 3B, encodes a LUX/BOA-like protein with a Myb/SANT domain and homeodomain-like fold. It is a sequence-specific DNA-binding transcription factor that localises to the nucleus and can homodimerise. The gene is associated with rhythmic process, upregulation of circadian rhythm, photoperiodism, regulation of photomorphogenesis, red/far red light signaling, entrainment of circadian clock, red, far-red light phototransduction, photoperiodism, flowering, regulation of photoperiodism, flowering, cytokinin signaling, regulation of stomatal movement, regulation of gene expression, polar cell growth, regulation of flower development, response to red light, chloroplast organization, and response to auxin. It has been linked to traits including photoperiod sensitivity, flowering time, leaf drying and senescence, seed viability, seedling hypocotyl length, hybrid incompatibility, temperature stress response, and plant morphology. Related genes in other species link the family to circadian rhythmicity, hypocotyl elongation, and flowering under non-inductive photoperiods.
