Gene Details:

• Gene ID: Zm00001d045601
• Gene Symbol: NUT1 NAC46 nac91 nactf91
• Gene Name: Necrotic upper tips1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• Necrotic upper tips1 (NUT1) is a transcription factor that mimics tassel blasting when mutated.
• NUT1 protein localizes to the developing protoxylem where it activates genes necessary for reinforcing the secondary cell wall, and thus enables these cells to withstand the high negative pressures required for long-distance water movement.
• NUT1 or its targets may be promising breeding targets to help maize resist the effects of rising temperatures in the future.
• NUT1 downstream target genes function in cell wall biosynthesis, apoptosis, and maintenance of xylem cell wall thickness and strength.
• NUT1 is induced during the adult/flowering phase of development in protoxylem, and when this gene is lost, the plants suffer both heat and drought stress phenotypes.
