Gene Details:

• Gene ID: Zm00001eb142500
• Gene Symbol: ZmICE1 ICE1 ZmICEa ZmSCRAM bhlh175
• Gene Name: INDUCER OF CBF EXPRESSION 1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Natural polymorphism of ZmICE1 contributes to amino acid metabolism that impacts cold tolerance in maize.
• Natural variation at the ZmICE1 promoter determines the binding affinity of the transcriptional activator ZmMYB39, a positive regulator of cold tolerance in maize, resulting in different degrees of ZmICE1 transcription and cold tolerance across inbred lines.
• ZmICE1 locus is associated with cold-regulated metabolites.
• ZmICE1 is induced by cold stress at transcription and protein levels, and positively regulates maize cold tolerance at the germination and seedling stages.
