ERN1 — Medicago truncatula

Summary

MTR_2G016730 (ERN1) in barrel medic (Medicago truncatula) on chromosome 2 encodes an AP2/ERF domain-containing protein with sequence-specific DNA-binding activity. The gene is associated with ethylene biosynthesis and signalling, cytokinin and ABA signalling, nitrogen fixation, nodulation, post-embryonic root development, cuticle and wax anabolism, organogenesis, floral meristem determinacy, regulation of secondary shoot formation, osmotic response, innate immunity, and both up- and downregulation of transcription. The product localises to the nucleus and is linked to ethylene sensitivity. Related genes in other species include WIN1, which is associated with cuticle biosynthesis, and ERN3, which is associated with nodulation.
