Gene Details:

• Gene ID:
• Gene Symbol: TaMKK3-A
• Gene Name: mitogen-activated protein kinase kinase
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Identified a mitogen-activated protein kinase kinase 3 (MKK3) gene (designated TaMKK3-A) by a map-based approach as a candidate gene for the seed dormancy locus Phs1 on chromosome 4A in bread wheat.
• Complementation analysis showed that transformation of a dormant wheat cultivar with the TaMKK3-A allele from a nondormant cultivar clearly reduced seed dormancy.
• TaMKK3-A gene expression, measured at the transcript level by RT-PCR, was detected not only in seeds but also in other tissues such as leaves, cotyledons, and roots
• Relative gene expression and dormancy level were correlated, therefore, higher TaMKK3-A gene expression may promote dormancy release.
