Studies on sweet corn: Stewart's wilt forecasting, the effect of maize dwarf mosaic on foliar diseases, and herbicide sensitivity
… probability of exceeding 1% and 5% incidence of Stewart’s wilt on sweet corn with different reactions to Pantoea stewartii, the effect of maize dwarf mosaic (MDM) on eight foliar diseases, and the effect of hybrid CYP genotype on sweet corn yield following postemergence applications of mesotrione …

Genetic Analysis of the Quorum Sensing Regulator EsaR
Pantoea stewartii subsp. stewartii is the causative agent of Stewart's wilt disease in maize plants. The bacteria are injected into the plant by corn flea beetles during feeding. They colonize the xylem and overproduce a capsular exopolysaccharide (EPS) at high cell densities. The production of EPS …

The Relative Efficiency of Replicates in Sweet Corn Hybrid Disease Nurseries and Posterior Probabilities as a Measure of Confidence in Assigning Sweet Corn Hybrids to Disease Reaction Categories
… each of three diseases (northern leaf blight, Stewart's wilt, and common rust), 1,000 simulated mean ratings each for 2,365 to 3,527 hybrids were produced as a random draw of two or three replicates. Boundaries for disease reaction categories from resistant (1) to susceptible (9) were assigned …

The in planta role of the global regulator Lrp in the bacterial phytopathogen Pantoea stewartii subsp. stewartii
Pantoea stewartii subsp. stewartii is a bacterial phytopathogen that causes the disease Stewart's wilt in corn. The insect vector Chaetocnema pulicaria, the corn flea beetle, transmits P. stewartii into corn plants through wounds in the leaves. The bacteria can then move to the xylem of the plant …

Analysis of the Quorum Sensing Regulons of Vibrio parahaemolyticus BB22 and Pantoea stewartii subspecies stewartii
… work, Vibrio parahaemolyticus and Pantoea stewartii subsp. stewartii. V. parahaemolyticus causes acute gastroenteritis in people who eat contaminated raw or undercooked shellfish. It is found in warmer marine waters and in rare cases, causes systemic infections when bacteria enter the body …

Role of the Leucine-responsive Regulatory Protein during growth of the bacterial corn pathogen Pantoea stewartii subspecies stewartii in the xylem environment
… as the Corn Belt where the bacterial disease Stewart's Wilt reduces crop yield. Pantoea stewartii subsp. stewartii (Pss) is transmitted into corn via the corn flea beetle insect vector, Chaetocnema pulicaria. As the beetle feeds on the corn plant leaves, Pss deposited in beetle feces enter the …

In planta studies of the corn pathogen Pantoea stewartii subsp. stewartii and applications of a corn-based industrial byproduct
… States and in the world. The causal agent of Stewart's wilt disease in corn, Pantoea stewartii subsp. stewartii, is a bacterial phytopathogen that is vectored into the plant by the corn flea beetle, Chaetocnema pulicaria. After entering the apoplast of the leaf, the bacteria cause water …

Investigation of Pantoea stewartii Quorum-Sensing Controlled Regulators and Genes Important for Infection of Corn
… This dissertation focuses on Pantoea stewartii subspecies stewartii (P. stewartii), an endosymbiont in the corn flea beetle gut that causes Stewart's wilt disease in corn. Gaining insights into the interactions occurring between this bacterial pathogen and its plant host may lead to …

Structure/Function Analysis of the Quorum-sensing Regulator EsaR from the Plant Pathogen Pantoea stewartii
Pantoea stewartii subsp. stewarti is the causative agent of Stewart's wilt disease in maize. Disease symptoms develop after the bacteria grow to high cell densities in the plant xylem and secrete an abundance of exopolysaccharide (EPS). EPS production is regulated by quorum sensing. Two regulatory …

Investigation of the quorum-sensing regulon in the corn pathogen Pantoea stewartii
Pantoea stewartii subsp. stewartii is a bacterium that causes Stewart’s wilt disease in corn plants. The bacteria are transmitted to the plants via an insect vector, the corn flea beetle Chaetocnema pulicaria. Once in the plant, the bacteria migrate to the xylem and grow to high cell densities, …
