NOBSC: National Onion Bacterial Strain Collection from 2020-2023 Survey

A U.S. survey from 2020 to 2023 across eleven states collected bacterial strains isolated from onions. The National Onion Bacterial Strain Collection (NOBSC) is maintained at the University of Georgia and focuses on six genera with important onion pathogens, including Burkholderia and Pantoea. It was assembled as part of a USDA-funded research initiative.

Use Cases

• Identify and study onion bacterial pathogens based on the collection's focus on six genera.
• Analyze the geographic distribution of onion pathogens based on strains isolated from eleven U.S. states.
• Support genomic or phenotypic research on bacterial strains isolated from onions.
• Develop management strategies for onion diseases using the repository of publicly available strains.

Strengths

• Collection focuses on six genera with important onion pathogens, including Burkholderia, Enterobacter, Pantoea, Pseudomonas, Rahnella and Xanthomonas.
• Strains were isolated from a U.S. survey conducted from 2020 to 2023 in eleven states.
• Dataset is publicly available under a CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the survey's eleven states.
