Gene Details:

• Gene ID: Zm00001eb284130
• Gene Symbol: ZmbHLH124
• Gene Name: bHLH-transcription factor 124
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmbHLH124 identified in maize recombinant inbred lines contributes to drought tolerance in crops.
• ZmbHLH124 in RIL73, named as ZmbHLH124T-ORG which origins from PH4CV and encodes a bHLH type transcription factor, was specifically up-regulated during drought stress.
• We found that ZmbHLH124T-ORG could directly bind the cis-acting elements in ZmDREB2A promoter to enhance its expression.
• The intact ZmbHLH124T-ORG contributed to drought tolerance in maize germplasm T-ORG.
• ZmbHLH124 can improve drought tolerance during reproductive stages.
• We identified a substitution in ZmbHLH124 that produced an early stop codon in sensitive lines (ZmbHLH124S-ORG). Overexpression of ZmbHLH124T-ORG, but not ZmbHLH124S-ORG, in maize and rice enhanced plant drought tolerance and up-regulated the expression of drought-responsive genes.
