Whole-Genome Resource of Seven Botrytis cinerea Sensu Lato Isolates with Resistance or Sensitivity to Seven Site-Specific Fungicides

Abstract

Botrytis cinerea is among the most important fungal pathogens in ornamental greenhouses due to its ability to cause severe Botrytis blight on various crops throughout the year. Fungicides are a key component in disease management programs, but frequencies of resistance in pathogen populations are notoriously high, leading to its role as a model system for fungicide resistance research. Here, we present seven high-quality genomes of North American B. cinerea sensu lato isolates collected from ornamental greenhouses with resistance (five) or sensitivity (two) to seven chemical classes representative of all commonly used site-specific fungicides. This resource can contribute to the exploration of multifungicide resistance mechanisms, host specificity, and geographic relatedness in populations of B. cinerea.
