Molecular genetic characterization of a pathogenicity-attenuated mutant of Pseudomonas syringae pathovar syringae

Creator:

Zhao, Yuqi

Abstract:

A pathogenicity locus of Pseudomonas syringae pv. syringae identified by Tn5 mutagenesis was investigated. The mutant strain PS9024 is attenuated for disease expression in its host, Phaseolus vulgaris, but produces the hypersensitive reaction (HR) in the nonhost, tobacco (Nicotina tabacum). A cosmid clone carrying 16 kilobases (kb) of contiguous genomic...

Molecular characterization of specificity and activity of the transposable element IS801

Creator:

Richter, Grace Yukiko

Abstract:

1S801 is a transposable element isolated from Pseudomonas syringae pathovar (pv.) phaseolicola, the causal agent of halo blight of bean. Fragments of the element are present in multiple copies on an indigenous plasmid, pMMC7105, of strain LR781, and have been implicated as sites of homologous recombination leading to imprecise excision...
