ERN1 — Medicago truncatula

Summary

MTR_7G085810 (ERN1, also known as MtRAP2.11) on barrel medic chromosome 7 encodes a protein with an AP2/ERF domain that binds sequence-specific DNA and transcription cis-regulatory regions. This gene is associated with nitrogen fixation, nodulation, ethylene sensitivity, ethylene metabolism and signalling, cytokinin signalling, and responses to stress, osmotic conditions, and potassium ion. It is linked to post-embryonic root development, organogenesis, floral meristem determinacy, regulation of secondary shoot formation, cuticle and wax anabolism, and upregulation of response to thirst. The encoded protein localises to the nucleus. Studies of related genes in other species link the family to potassium uptake and nitrate transport.
