Gene Details:

• Gene ID: TraesCS3B02G092800
• Gene Symbol: TaNAC019-B
• Gene Name: NAC domain-containing protein 19
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• The endosperm-specific transcription factor TaNAC019 regulates glutenin and starch accumulation and its elite allele improves wheat grain quality.
• Mechanism of TaNAC019-mediated regulation of SSP and starch accumulation in wheat seeds.
• TaNAC019 is a new candidate gene for improving processing quality in wheat.
• Triple knock-out mutants of all three TaNAC019 homoeologs exhibited reduced transcript levels for all SSP types and genes involved in starch metabolism, leading to lower gluten and starch contents, and in flour processing quality parameters.
• TaNAC019 also indirectly regulated the expression of TaSPA, an ortholog of maize Opaque2 that activates SSP accumulation.
• Identified an elite allele (TaNAC019-BI) associated with flour processing quality, providing a candidate gene for breeding wheat with improved quality.
