ERF3 — Solanum tuberosum

Summary

PGSC0003DMG400016003, designated ERF3 on potato chromosome 5, encodes an AP2/ERF domain-containing protein with DNA binding and transcription factor activity. The gene is associated with responses to oxygen levels, freezing, high light intensity, nematodes, and L-glutamate, as well as with regulation of ethylene-mediated signaling, jasmonic acid-mediated systemic resistance, stomatal development and closure, root meristem size, and phloem or xylem histogenesis. It has been linked to traits including anthocyanin content, photosynthetic rate, seed size, shoot branching, adventitious root number, phosphorus uptake, and responses to powdery mildew, UV-B light, osmotic stress, and insects. Studies of related ERF family members in other species connect the family to resistance to Meloidogyne incognita, Verticillium, and Botrytis cinerea, as well as to cadmium tolerance, salt acclimation, and stress priming.
