DESI-MSI Imaging Data on Biocontrol Agents for Tomato Pathogen Protection

577.5 KB of mass spectrometry imaging data from a dual culture of Bacillus thuringiensis and the plant pathogen Phytophthora capsici, identifying seven unique phenotypic regions. The dataset, authored by Jamille Y. Robinson and shared on figshare, evaluates the biocontrol effectiveness of four Bacillus species against Phytophthora capsici infection in tomato plants. It was last updated on 2026-05-07.

Use Cases

• Identify molecular markers of biocontrol activity based on spatially resolved mass spectrometry data.
• Compare the in vitro and in vivo efficacy of different Bacillus species as described in the study.
• Analyze the biochemical interactions in a dual-culture system to understand pathogen inhibition mechanisms.
• Validate desorption electrospray ionization–mass spectrometry imaging (DESI-MSI) workflows for agricultural microbiology applications.

Strengths

• Dataset is focused on a specific, agriculturally relevant pathogen (Phytophthora capsici) and four candidate biocontrol agents.
• The description includes specific quantitative results, such as a 94.4% increase in root length for treated plants.
• Data is shared under a clear, open license (CC-BY-NC-4.0).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 577.5 KB size suggests a limited scope, likely containing processed results rather than raw spectral data.
