ERF1 — Lactuca sativa

Summary

LsERF1 (ERF1) on chromosome 5 of garden lettuce encodes a DNA-binding transcription factor of the AP2/ERF domain family, with transcription coactivator activity and sequence-specific DNA binding. The gene is associated with ethylene signaling, defense responses, and responses to drought, salinity, and red/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 disease tolerance, resistance to Botrytis cinerea and necrotrophic pathogens, salt and drought tolerance, heat tolerance, photosynthetic rate, respiration rate, flowering time, and root morphology traits such as lateral root development and primary root elongation. The gene is also associated with auxin and jasmonic acid signaling, stomatal aperture, and post-anoxia recovery.
