Gene Details:

• Gene ID: TraesCS3B02G608800
• Gene Symbol: TdDof-B SSt1
• Gene Name: dof zinc finger protein DOF3.6-like
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Copy number variation of TdDof controls solid-stemmed architecture in wheat.
• We identify TdDof as the causal gene that controls stem solidness in wheat. We show that copy number gain of TdDof correlates with its increased expression and the solid-stem phenotype.
• Our results suggest TdDof could function as a key regulator of genes involved in programmed cell death of the pith parenchyma cells.
• Molecular analysis revealed that hollow-stemmed wheat cultivars such as Kronos carry a single copy of TdDof, whereas solid-stemmed cultivars such as CDC Fortitude carry multiple identical copies of the gene.
• Deletion of all TdDof copies from CDC Fortitude resulted in the loss of stem solidness, whereas the transgenic overexpression of TdDof restored stem solidness in the TdDof deletion mutant pithless1 and conferred stem solidness in Kronos.
