Characterization of the Plasmids of the Pathogenic Plant Bacterium Erwinia amylovora in Washington and Oregon

Creator:

Carey, Alyssa B.

Abstract:

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,...

Contribution of native plasmids to fitness of Pantoea vagans C9-1, a biological control agent for fire blight of apple and pear

Creator:

Klein, Jeannie M.

Abstract:

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...

Induction of apple defense genes by Erwinia amylovora and biological control agents

Creator:

Bauer, Lisa M.

Abstract:

Fire blight is a serious disease of apple and pear trees caused by the bacterium, Erwinia amylovora. This bacterium harbors a pathogenesis mechanism known as the Hrp secretory operon which induces some resistance genes and suppresses other resistance genes in the host plant following invasion. While previous researchers analyzed expression...
