DREB2 — Phaseolus vulgaris

Summary

PHAVU_008G220400 (PvDREB2) on chromosome 8 of French bean encodes a protein with an AP2/ERF domain and DNA-binding domain, annotated with DNA binding transcription factor activity, NAD ADP-ribosyltransferase activity, and ubiquitin-protein transferase activity. The gene is associated with diverse biological processes including upregulation of chlorophyll breakdown, leaf senescence, defense response, flower development, photoperiodism, stomatal complex development, trichome branching, lateral root morphogenesis, and responses to superoxide, ozone, and glucose-mediated signaling. It localizes to the nucleus, cytoplasm, nucleolus, and RNA polymerase II, IV, and V complexes. Associations with agronomic traits include yield, plant height, seed growth, leaf senescence, photosynthetic rate, transpiration rate, stomatal resistance, water stress response, osmotic sensitivity, and nitrate sensitivity. Related genes in other species are linked to dehydration tolerance, heat stress tolerance, and drought stress response.
