Description
594 bacterial isolates from tomato rhizosphere and phyllosphere were analyzed to identify antagonists of Phytophthora infestans. The dataset, created by Philemon Orwa and last updated on 2026-05-01, includes results from culture-dependent isolation, functional profiling, and 16S rRNA microbiome analysis of plants from organic farms in Germany. It identifies 84 isolates that inhibited P. infestans and links community-level microbiome patterns to effective biocontrol candidates.
Use Cases
Identify bacterial genera with broad-spectrum antagonistic potential based on siderophore and lytic enzyme activity profiles.
Analyze the relationship between microbial community assembly and disease state based on soil origin and plant compartment data.
Map cultured bacterial antagonists to their relative abundance in amplicon sequence variant (ASV) data to study resilience.
Evaluate the effectiveness of specific isolates like Pseudarthrobacter sp._Pb177 for in planta biocontrol assays.
Strengths
Includes data from 594 bacterial isolates, with 84 showing inhibition of Phytophthora infestans.
Functional screening identified 28 isolates with broad-spectrum antagonistic potential, characterized by specific enzyme activities.
Links culture-dependent results with amplicon-based microbiome analysis from two soil origins and multiple plant compartments.
Limitations
Row count and column-level documentation are unknown, requiring manual inspection after download.
The dataset is small at 46.7 KB, indicating limited scope.
Geographic coverage is specific to organic tomato farms in the Rhine-Main region of Germany.
