Role of Stress-Induced Proteins RpoS and YicC in the Persistence of subsp. Serotype Typhimurium in Tomato Plants.

Understanding the functional role of bacterial genes in the persistence of in plant organs can facilitate the development of agricultural practices to mitigate food safety risks associated with the consumption of fresh produce contaminated with spp. Our study showed that subsp. serotype Typhimurium (strain MDD14) persisted less in inoculated tomato plants than other Typhimurium strains tested (JSG210, JSG626, JSG634, JSG637, JSG3444, and EV030415; < 0.

Discovery and Characterization of Low-Molecular Weight Inhibitors of .

Plant pathogenic bacteria in the genus cause economically important diseases, including bacterial wilt of cucurbits caused by . Conventional bactericides are insufficient to control this disease. Using high-throughput screening, 464 small molecules (SMs) with either cidal or static activity at 100 µM against a cucumber strain of were identified.

Imidazole and Methoxybenzylamine Growth Inhibitors Reduce Persistence in Tomato Plant Tissues.

Small molecules (SMs) 1, 3, 4, and 5 are novel growth inhibitors of . These SMs are not toxic to tomato plant tissues including fruits. Combining biocontrol agents and SMs enhanced the control of in infected plants.

Specific Environmental Temperature and Relative Humidity Conditions and Grafting Affect the Persistence and Dissemination of subsp. Serotype Typhimurium in Tomato Plant Tissues.

Little is known about the abiotic factors contributing to the preharvest persistence of in tomato tissues. Therefore, we investigated the effects of specific environmental conditions and contamination methods on the persistence and dissemination of subsp. serotype Typhimurium (JSG626) in tomato plants.

Differential Colonization Dynamics of Cucurbit Hosts by Erwinia tracheiphila.

Bacterial wilt is one of the most destructive diseases of cucurbits in the Midwestern and Northeastern United States. Although the disease has been studied since 1900, host colonization dynamics remain unclear. Cucumis- and Cucurbita-derived strains exhibit host preference for the cucurbit genus from which they were isolated.
