Pepper Plant Transcriptome and Metabolome Data for Spider-Mite Herbivory Defense

Combined transcriptome and metabolome data from two pepper genotypes with differing susceptibility to spider-mite infestation. The data was generated by researchers at Wageningen University & Research to study jasmonic acid and salicylic acid signaling pathways in plant defense. Analysis suggests the more resistant genotype exhibited a larger increase in endogenous JA and secondary metabolites upon infestation.

Use Cases

• Compare transcriptome profiles between mite infestation and exogenous jasmonic acid treatment.
• Identify differentially expressed genes involved in metabolic and lipid metabolic processes from the transcriptome data.
• Analyze changes in terpenoid and flavonoid production from the untargeted metabolome data.
• Investigate the role of WRKY transcription factors and pathogen-related defense responses induced by mite infestation.
• Correlate volatile and non-volatile secondary metabolite levels with genotype resistance to spider mites.

Strengths

• Data integrates transcriptomic and metabolomic profiles for a multi-omics view of plant defense.
• Compares two distinct pepper genotypes with different susceptibility levels to spider mites.
• Includes experimental conditions for both direct mite infestation and exogenous hormone (JA) treatment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
