ERF1 — Phaseolus vulgaris

Summary

PHAVU_007G273000, designated PvERF1, encodes a protein containing an AP2/ERF domain and is annotated with DNA-binding and transcription coactivator activities. This French bean gene on chromosome 7 is associated with responses to drought, salinity, osmotic stress, ethylene, jasmonic acid, and red and far-red light. It is linked to trichome papilla formation and branching, flavonoid biosynthesis, fruit ripening, and flower development. Associations include disease tolerance, pathogen resistance (including to Botrytis cinerea), heat and salt tolerance, drought tolerance, and root morphology traits such as lateral root emergence and primary root elongation. The gene is also connected to ethylene sensitivity, auxin sensitivity, flowering time, and hypocotyl elongation. Related genes in other species are linked to ethylene response, resistance to fungal pathogens including Fusarium oxysporum and Plectosphaerella cucumerina, and drought stress response.
