ERF1 — Lactuca sativa

Summary

LsERF1, encoded by the gene LSAT_V11C700351220 on chromosome 7 of garden lettuce (Lactuca sativa), is a DNA-binding transcription factor containing an AP2/ERF domain. It is associated with transcription corepressor and coactivator activities, kinase binding, and protein homodimerization. This gene is linked to a wide range of biological processes, including cellular responses to drought and salinity, ethylene and jasmonic acid signaling, defense responses, trichome and floral meristem development, and glucosinolate metabolism. It localizes to the nucleus, cytosol, and mediator complex. Associations with agronomically important traits include drought tolerance, submergence tolerance, disease tolerance, photosynthetic rate, flowering time, and root and shoot morphology. Studies of related genes in other species link the family to cold, salt, and drought stress tolerance, as well as resistance to pathogens such as TYLCV and Pseudomonas syringae.
