High-throughput chemical genomic screening: a step-by-step workflow from plate to phenotype

Area of Science:

• Microbial Systems Biology
• Functional Genomics
• Chemical Genomics

Background:

• High-throughput chemical genomics links gene function to phenotype using strain libraries.
• Existing methods lack standardized workflows, limiting broader microbial research applications.
• Phenotypic profiles are crucial for functional annotations and identifying drug targets.

Purpose of the Study:

• To provide a step-by-step guide for conducting reproducible chemical genomics screens.
• To introduce a scalable, end-to-end protocol integrating experimental, imaging, and computational steps.
• To facilitate the systematic exploration of gene-environment interactions and microbial stress responses.

Main Methods:

• Development of a cohesive framework for high-throughput screening across microbial species.
• Integration of experimental, imaging, and computational analyses.
• Standardization of workflows for generating consistent, high-quality phenotypic data.

Main Results:

• A scalable, end-to-end protocol for chemical genomics screening is established.
• The protocol enables consistent generation of high-quality phenotypic data for large-scale analyses.
• The workflow supports exploration of gene-environment interactions and antimicrobial resistance.

Conclusions:

• This standardized protocol enhances the utility of chemical genomics in microbial research.
• The workflow bridges benchwork and computational analysis, expanding tools for microbial systems biologists.
• The method supports research in microbiome studies, synthetic biology, and microbial communities.
