Pea Powdery Mildew Resistance: Transcriptomic and Metabolomic Profiles of Two Cultivars

Integrated transcriptomic and metabolomic data from a study comparing susceptible and resistant pea varieties during powdery mildew infection. The dataset includes profiles for 34,566 annotated genes and 1,754 identified metabolites across three infection time points. It was authored by Yuanli Li and last updated on April 22, 2026.

Use Cases

• Identify key genes and metabolites involved in plant defense based on differential expression and accumulation analysis.
• Model gene-metabolite regulatory networks underlying disease resistance based on correlation data mentioned in the description.
• Validate molecular markers for breeding powdery mildew-resistant pea varieties based on identified biosynthetic pathways.
• Compare temporal dynamics of defense responses based on data from three infection stages (0, 3, and 6 days post-inoculation).

Strengths

• Multi-omics integration covering 34,566 annotated genes and 1,754 identified metabolites.
• Temporal resolution with data from three distinct infection stages (0, 3, and 6 days post-inoculation).
• Clear biological contrast between susceptible (Longwan 3) and resistant (Longwan 5) pea cultivars.
• Openly licensed under CC-BY-4.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data is contained within a 15.4 MB PDF, which may require extraction to access structured data.
