ERF1 — Lactuca sativa

Summary

LsERF1 (ERF1) on chromosome 4 of garden lettuce encodes a DNA-binding transcription factor with an AP2/ERF domain, also annotated with transcription corepressor and coactivator activities, kinase binding, and protein homodimerization. It is associated with diverse processes including cellular responses to drought and salinity, downregulation of ethylene signaling, jasmonic acid-mediated systemic resistance, glucosinolate metabolism, gibberellin biosynthesis, trichome branching, floral meristem determinacy, and phloem or xylem histogenesis. The gene is linked to traits such as drought tolerance, submergence tolerance, photosynthetic rate, flowering time, disease tolerance, stomatal opening, and root morphology. Studies of related genes in other species connect the family to salt tolerance, cold stress response, pathogen resistance, leaf senescence, and transcriptional repression.
