ERN1 — Medicago truncatula

Summary

MTR_6G012970 (ERN1) in barrel medic (Medicago truncatula) on chromosome 6 encodes a protein with an AP2/ERF domain, a DNA-binding domain superfamily member that binds sequence-specific DNA and transcription cis-regulatory regions. The gene is associated with nitrogen fixation, nodulation, ethylene biosynthesis and signalling, cytokinin signalling, ABA signalling, osmotic response, innate immunity, cuticle and wax anabolism, post-embryonic root development, organogenesis, floral meristem determinacy, and regulation of secondary shoot formation. It is also linked to ethylene sensitivity. The encoded protein localises to the nucleus. Studies of related genes in other species connect the AP2/ERF family to similar developmental and stress-associated processes, though these relationships are not yet established in barrel medic.
