Creator:: Szabo, Leslie J.
Abstract:: A strain of the phytopathogenic bacterium Pseudomonas syringae pv. phaseolicola, a pathogen of common bean Phaseolus vulgaris, harbors a 150 kilobase pair (kb) plasmid pMC7105. In one strain, LR719, pMC7105 is stably integrated in the bacterial chromosome. Imprecise excision of the pMC7105 replicon has been shown to result in the...

Abstract:: Pulsed-field gel electrophoresis (PFGE) of the strains representing the 14 races of U. hordei, the causal agent of covered smut on barley, revealed extensive polymorphism in chromosome length and number. The purpose of this study was to determine by two approaches the exact chromosome number for each U. hordei race,...

Abstract:: Six plant pathogenic isolates of Pseudomonas syringae pv. glycinea, the causal agent of bacterial blight of Glycine max (L.) Merrill, and one isolate of P. syringae pv. phaseolicola, the causal agent of halo blight of Phaseolus vulgaris L., have been examined for the presence of circular duplex deoxyribonucleic acid (DNA)....

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...

Creator:: Abdennadher, Mourad
Abstract:: Inbreeding of the avirulent physiologic race 8 strains of Ustilago hordei was purported to have increased its pathogenicity in a stepwise manner that led to a highly pathogenic race, designated race 14. The analysis of electrophoretic karyotypes and restriction fragment length polymorphism profiles detected with a telomere-specific probe (TelomereRFLP) in...

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...
