EIL1 — Arabidopsis thaliana

Summary

AT2G27050 (EIL1) encodes ETHYLENE-INSENSITIVE3-like 1, a protein containing an EIN3-like DNA-binding domain that localises to the nucleus and cytoplasm. The protein exhibits sequence-specific DNA binding, transcription factor activity, and associations with chromatin, histones, kinases, and other proteins. In Arabidopsis, EIL1 is linked to nitrate deficiency response and hyponasty response to high humidity. The gene is associated with numerous biological processes including synergid death, leaf abscission, root system development, nitrate import, regulation of iron transport, defense response to insects, ascorbate biosynthesis, TOR signaling, and response to gravity and hormones. EIL1 is associated with traits such as iron sensitivity, submergence tolerance, seed protein content, branch angle, shoot growth angle, phosphorus response, and seed yield. Studies of related genes in other species link the family to fruit ripening, grain size, root hair development, and flower development traits.
