Pea Powdery Mildew Resistance Multi-Omics Data Across Three Infection Stages

Integrated transcriptomic and metabolomic analysis of susceptible and resistant pea varieties reveals the central role of phenylpropanoid biosynthesis. The data profiles 17,554 metabolites and 34,566 annotated genes across three infection stages (0, 3, and 6 days post-inoculation). Author Yuanli Li published this dataset on figshare in April 2026 under a CC-BY-4.0 license.

Use Cases

• Identify key resistance genes based on differential expression profiles between susceptible and resistant pea cultivars.
• Analyze metabolic reconfiguration in plant defense based on the 1754 identified metabolites.
• Validate gene-metabolite correlations in the phenylpropanoid biosynthesis pathway.
• Discover molecular markers for precision breeding of powdery mildew-resistant pea varieties.

Strengths

• Multi-omics integration of transcriptomic and metabolomic data.
• Profiles two distinct pea cultivars across three time points for dynamic analysis.
• Identifies 1754 metabolites and 34566 annotated genes.
• Clear biological finding linking phenylpropanoid biosynthesis to resistance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is relatively small at 7.7 MB, suggesting a summarized or processed form of the raw omics data.
