ICE1 — Arabidopsis thaliana

Summary

AT3G26744 (ICE1, also known as SCRM) in Arabidopsis thaliana encodes a basic helix-loop-helix (bHLH) transcription factor that binds core promoter and cis-regulatory sequences and acts as a DNA-binding transcription activator. ICE1 is associated with cold temperature response, pre-harvest sprouting, flavone metabolism, strigolactone anabolism, and regulation of salicylic acid metabolic process. The gene is linked to stomatal development, differentiation, and patterning, as well as epidermal cell differentiation and pavement cell differentiation. ICE1 has been connected to numerous agronomic traits including seed volume, germination ratio, biomass yield, leaf elongation rate, nitrate content, carbohydrate content, seed protein content, leaf water potential, turgor pressure, potassium uptake, copper concentration and sensitivity, aluminum response trait, aphid response trait, photoperiod-sensitive flowering time trait, and temperature stress response trait. The protein localizes to the nucleus, cytosol, and plastid.
