Gene Details:

• Gene ID: Zm00001eb036920
• Gene Symbol: ZmNAC48
• Gene Name: NAC-transcription factor 48
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• A natural antisense transcript acts as a negative regulator for the maize drought stress response gene ZmNAC48.
• Arabidopsis plants overexpressing ZmNAC48 had improved drought tolerance, lower rate of water loss, enhanced stomatal closure, and higher rates of survival. Transient expression in both maize protoplasts and tobacco leaves indicated that cis-NATZmNAC48 reduced ZmNAC48 expression.
• Taken together, our study indicates that both ZmNAC48 and cis-NATZmNAC48 are involved in plant drought stress responses, and that the double-stranded RNA-dependent mechanism is involved in the interaction between cis-NATZmNAC48 and ZmNAC48. Additionally, cis-NATZmNAC48 may negatively regulate ZmNAC48 to affect stomatal closure of maize.
• Overexpression of ZmNAC48 enhances stomatal closure, conferring drought tolerance in transgenic Arabidopsis.
• cis-NATZmNAC48 and ZmNAC48 transcripts have the potential to generate nat-siRNAs in response to drought stress.
