BOA — Phaseolus vulgaris

Summary

PHAVU_011G062100, designated PvBOA, encodes a LUX/BOA-like Myb-domain transcription factor that localises to the nucleus and exhibits sequence-specific DNA binding, protein homodimerization and DNA-binding transcription factor activity. In French bean, PvBOA is associated with circadian rhythmic processes, photoperiodism, flowering-time regulation, red/far-red light signalling, photomorphogenesis, stomatal movement, chloroplast organisation and cytokinin signalling. The gene is linked to agronomically relevant traits including flowering time, photoperiod sensitivity, seed viability and development, leaf growth and senescence, seedling hypocotyl length, starch mobilisation, temperature stress response and hybrid incompatibility. Related genes in other species are linked to circadian clock function, hypocotyl elongation, freezing tolerance, disease resistance and stomatal regulation.
