ERF1 — Lactuca sativa

Summary

LsERF1 (ERF1) on lettuce chromosome 5 encodes a protein with an AP2/ERF domain, annotated with DNA binding transcription factor activity, transcription corepressor activity, kinase activity, and chitosan and chitin binding. It is associated with responses to flooding, chitin, and bacterial and fungal molecules, as well as ethylene and abscisic acid signaling, gibberellin biosynthesis, seed germination, and vascular tissue pattern formation. The gene is linked to traits including bacterial blight disease resistance, submergence tolerance, ethylene and brassinosteroid sensitivity, photosynthetic rate, stomatal closure, flowering time, and salt tolerance. Studies of related genes in other species connect the family to drought stress response, abscisic acid sensitivity, transpirational water loss, and phenolic compound biosynthesis.
