ERF1 — Lactuca sativa

Summary

LsERF1 (ERF1) on chromosome 2 of garden lettuce encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription coactivator activity. The gene is associated with ethylene signaling and biosynthesis, defense responses, and responses to drought, salt, and red and far-red light. It is linked to trichome papilla formation and branching, flower development, fruit ripening, seed germination, and gibberellin biosynthesis. Associations with agronomic traits include respiration rate, photosynthetic rate, ethylene and auxin sensitivity, jasmonic acid content, disease tolerance, and root and floral organ development traits. The encoded protein localizes to the nucleus and the mediator complex. Studies of related genes in other species link the family to ethylene response, drought response, and resistance to fungal and bacterial pathogens.
