Reference strains in collection

We have a collection of non-pathogenic or opportunistic xanthomonads, some of which belong to potentially new species and these strains belonging to new species could serve as reference strains. In addition, we have Pseudomonas strains isolated from tomato, pepper, cucurbits that falls into potentially new species. These are particularly interesting given these have been isolated from a broad host range and continue to cause sporadic outbreaks in the fields. We also have ongoing collection of Xanthomonads from tomato and pepper, isolated from disease outbreaks collected over the span of several years and continuing, including those belonging to new lineages within species and those with recent host range expansion.

Sequencing data in collection

16S/ITS, genomes for some bacterial isolates
