ERF1 — Beta vulgaris subsp. vulgaris

Summary

BvERF1 (BVRB_8G182660) on sugar beet chromosome 8 encodes a protein with an AP2/ERF domain and DNA-binding domain, possessing transcription corepressor and coactivator activities, sequence-specific DNA binding, and protein homodimerization activity. It localizes to the nucleus, cytosol, and mediator complex. The gene is associated with regulation of ethylene-mediated signaling, cellular responses to drought and salinity, induced systemic resistance via jasmonic acid, glucosinolate and sucrose metabolism, trichome branching, floral meristem determinacy, and phloem or xylem histogenesis. It has been linked to traits including drought tolerance, submergence tolerance, photosynthetic rate, flowering time, disease tolerance, root morphology, and auxin sensitivity. Studies of related genes in other species connect the family to cold and salt tolerance, pathogen resistance, leaf senescence, and root elongation.
