ERF1 — Lactuca sativa

Summary

LsERF1, encoded by the gene LSAT_V11C500229800 on lettuce chromosome 5, is a member of the AP2/ERF domain superfamily and possesses DNA-binding transcription factor activity, along with protein kinase, chitosan-binding, and transcription corepressor activities. In lettuce, this gene is associated with responses to flooding, chitin, and molecules of bacterial and fungal origin, as well as with ethylene and abscisic acid signaling, gibberellin biosynthesis, seed germination, and vascular tissue pattern formation. It is linked to traits including bacterial blight disease resistance, submergence tolerance, ethylene and abscisic acid sensitivity, photosynthetic rate, flowering time, and heat stress response. Studies of related genes in other species connect the family to drought stress response, abscisic acid sensitivity, bacterial and fungal disease resistance, and thermotolerance.
