ERF2 — Brachypodium distachyon

Summary

BdERF2 (BRADI_2G50035V3) on chromosome 2 of Brachypodium distachyon encodes an AP2/ERF domain-containing protein with DNA-binding transcription factor activity. It is associated with the regulation of ethylene-mediated signaling, defense responses, induced systemic resistance via jasmonic acid signaling, phloem or xylem histogenesis, fruit ripening, cell division, and response to nematodes. The gene is linked to ethylene sensitivity, insect herbivory resistance, abiotic and biotic stress responses, salt stress, post-anoxia recovery, and ABA-related processes. Studies of related genes in other species connect the family to GCC box-dependent transcription, jasmonate-responsive gene expression, disease resistance, heat stress tolerance, cadmium tolerance, and lateral root emergence. In crop relatives, the family has been linked to traits including grain number, seed size, submergence tolerance, blast resistance, and carotenoid content.
