Identification of a nonpathogenic Erwinia amylovora guaB mutant.

1997-08-01

Abstract excerpt

A nonpathogenic Erwinia amylovora transposon mutant that has an insertion in the guaB gene was isolated. The mutation results in a nutritional requirement for guanine or xanthine, and loss of ability to produce ooze on immature pear fruit and to cause symptoms in the apple seedling assay. The mutant expressed other known virulence determinants including extracellular polysaccharide and had an intact hrp/dsp cluste...
