Gene Details:

• Gene ID: Zm00001eb135910
• Gene Symbol: NAC7 nactf108
• Gene Name: NAC-transcription factor 108
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• NAC7 as a target for improving functional stay-green and yields in maize and other crops.
• NAC7 regulates genes involved in protein turnover, photosynthesis and trehalose-6-phosphate pathways to delay senescence and increase yield in maize.
• Reducing NAC7 expression increased plant leaf area, biomass and nitrogen content of the leaf and stalk tissues.
• NAC7 RNAi events targeted on protein turnover pathways to delay senescence.
• Transgenic maize lines where NAC7 was down-regulated by RNAi showed delayed senescence and increased both biomass and nitrogen accumulation in vegetative tissues, demonstrating NAC7 functions as a negative regulator of the stay-green trait.
• We further determined the putative target of NAC7 and provided a logical extension for the role of NAC7 in regulating resource allocation from vegetative source to reproductive sink tissues.
