Tomato Microbiome and Antagonist Data for Late Blight Control

594 bacterial isolates from tomato rhizosphere and phyllosphere were screened to identify antagonists of Phytophthora infestans. The research, authored by Philemon Orwa and last updated in May 2026, links microbial community profiling with functional screening and in planta assays. It identifies 84 isolates that inhibited P. infestans, with Pseudarthrobacter sp._Pb177 highlighted as a novel and effective antagonist.

Use Cases

• Identifying bacterial biocontrol candidates based on functional profiling of lytic enzymes and siderophores mentioned in the description.
• Analyzing links between microbiome community structure and disease resilience in tomato plants.
• Studying the distribution of low-abundance bacterial antagonists across different soil origins and plant compartments.
• Comparing the effectiveness of different bacterial genera (e.g., Pseudomonas, Bacillus, Streptomyces) against Phytophthora infestans.

Strengths

• Includes data from 594 bacterial isolates, with 84 showing inhibition of Phytophthora infestans.
• Functional screening identified 28 isolates with broad-spectrum antagonistic potential.
• Combines culture-dependent isolation, 16S rRNA microbiome analysis, and in planta assays.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in a 1.1 MB PDF, which may require extraction for computational analysis.
