Transcriptomic Changes in Wheat Under Heat Stress and Hessian Fly Infestation

Liecheng Zhu's dataset from 2026 contains transcriptomic profiles comparing resistant and susceptible wheat cultivars under normal and heat-stressed conditions. The data likely includes gene expression changes associated with heat-induced susceptibility to Hessian fly infestation. The study identified 74 candidate genes consistently regulated in susceptible states.

Use Cases

• Identify candidate genes for durable pest resistance based on the 74 susceptibility-associated genes.
• Analyze transcriptional reprogramming in wheat under combined biotic and abiotic stress.
• Compare defense signaling pathways, such as auxin and salicylic acid activity, between resistant and susceptible plant states.
• Investigate molecular mechanisms of heat-compromised resistance in crops.

Strengths

• The dataset is derived from a controlled comparative study using near-isogenic wheat lines.
• Functional annotation links 74 identified genes to specific biological pathways like auxin and salicylic acid signaling.
• Phenotypic validation showed a single 24-hour heat treatment caused over 70% of resistant plants to become susceptible.

Limitations

• The dataset is very small at 28.8 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
