Pennycress Heat Stress Tolerance Data from Four Growth Chamber Experiments

A figshare dataset authored by Nikhil S. Jaikumar in 2026 contains experimental results on heat tolerance in pennycress mutants. It likely includes measurements of pollen viability, lipid peroxidation, proline content, and seed yield under controlled temperature regimes. The data supports research on improving oilseed crop resilience through genetic modification.

Use Cases

• Analyze the relationship between reduced polyunsaturated fatty acids and pollen viability under elevated temperatures.
• Compare seed yield impacts between different gene-edited mutant lines (fad2, rod1) and wild-type plants after heat stress.
• Evaluate lipid peroxidation and proline accumulation as stress indicators in leaves and silicles.
• Model the auxiliary benefits of altered seed oil composition on overall plant heat tolerance.

Strengths

• Includes specific quantitative results: fad2 mutant pollen viability was 71% at 28°C compared to 37% for wild-type.
• Compares multiple mutant lines (fad2, rod1, fae1) across four distinct growth chamber experiments.
• Measures multiple physiological responses: pollen viability, lipid peroxidation, proline content, and seed yield.

Limitations

• Column-level documentation is absent; field semantics must be inferred from the PDF description.
• Row count is unknown, which may limit suitability assessment for statistical analysis.
• The dataset is small (1.3 MB), suggesting it may contain summary results rather than raw experimental observations.
