Succinate dehydrogenase (Sdh) inhibitor fungicides, such as boscalid, are effective for the management of gray mold caused by the fungal pathogen Botrytis cinerea. Unfortunately, resistance to boscalid was common among isolates of the pathogen from small fruits grown in Oregon. Boscalid-resistance is commonly associated with mutations in Sdh, especially in...
Erwinia amylovora is a plant pathogenic bacterium that causes the destructive disease fire blight of apple and pear. We examined the plasmid content of a collection of 305 isolates of E. amylovora from Washington and Oregon with PCR assays and RFLP. Nearly all isolates of E. amylovora carried plasmid pEA29,...
Pantoea vagans C9-1 (C9-1) is a biological control agent sprayed onto apple and pear trees during bloom for suppression of fire blight, a devastating bacterial disease caused by Erwinia amylovora. Prior bioinformatics studies of C9-1 focused on predicted phenotypes associated with the three native megaplasmids, pPag1, pPag2, and pPag3, and...
