ERF1 — Lactuca sativa

Summary

LsERF1, encoded by the gene LSAT_V11C100049220 on chromosome 1 of garden lettuce (Lactuca sativa), is a DNA-binding transcription factor containing an AP2/ERF domain and exhibiting transcription corepressor and coactivator activities, kinase binding, and protein homodimerization. It is associated with diverse biological processes including cellular responses to drought and salinity, ethylene and jasmonic acid signaling, glucosinolate metabolism, gibberellin biosynthesis, trichome and floral meristem development, and phloem or xylem histogenesis. The gene is linked to agronomically important traits such as drought tolerance, submergence tolerance, high temperature stress response, photosynthetic rate, flowering time, disease tolerance, and root and shoot morphology. Studies of related genes in other species connect the family to cold and salt tolerance, pathogen resistance, leaf senescence, and anthocyanin production.
