ERF1 — Arabidopsis thaliana

Summary

AT3G23240, designated ERF1 (ethylene response factor 1) on Arabidopsis thaliana chromosome 3, encodes a DNA-binding transcription factor with an AP2/ERF domain and transcription coactivator activity. ERF1 is associated with ethylene response, fungal resistance to Plectosphaerella cucumerina and Fusarium oxysporum, and resistance to Pseudomonas syringae. The gene has been connected to GCC box-dependent transcription, cellular responses to drought and salinity, chlorophyll breakdown, camalexin and phytoalexin biosynthesis, and shade avoidance. It is linked to traits including floral organ size, cellulose content, photosynthetic rate, chlorophyll content, flowering time, root length, salt tolerance, and disease tolerance. ERF1 localises to the nucleus and mediator complex. Related genes in other species are linked to stress tolerance and pathogen defense.
