Motility and Chemotaxis of Erwinia Amylovora
… and cultural factors influence the motility of Erwinia amylovora by affecting either flagella synthesis of motility itself. Flagella synthesis is temperature dependent with an optimum at 18-23(DEGREES)C. However, bacterial cells grown at these temperatures are actively motile even at …

Regulation of amylovoran biosynthesis in Erwinia amylovora
… blight, caused by the gram-negative bacterium Erwinia amylovora, is one of the most devastating bacterial diseases for the apple and pear industry. Two pathogenicity factors strictly required for E. amylovora to cause disease are the exopolysaccharide amylovoran and the type III secretion …

Characterization of major virulence regulators of Erwinia amylovora
Erwinia amylovora is the causal agent of the devastating fire blight disease which is a major concern to the apple and pear industry. Fire blight costs millions of dollars of economic losses all over the world. Exopolysaccharide (EPS) amylovoran and type III secretion system (T3SS) are two major …

Posttranscriptional and posttranslational regulation of virulence in erwinia amylovora
Erwinia amylovora is the causal agent of fire blight, the most destructive bacterial disease of the Rosaceae family plants. Two virulence factors, the type III secretion system (T3SS) and the exopolysaccharide (EPS) amylovoran, are strictly required for its pathogenicity. Our previous studies have …

Motility and Chemotaxis of Erwinia Herbicola and Its Effect on Erwinia Amylovora (Biological Control, Phytobacteriology, Fire Blight)
… required for motility and chemotaxis in Erwinia herbicola (112Y) were determined by the capillary assay. Actively motile cells were selected from the periphery of swarming colonies grown on soft agar (0.25%) modified Emerson's medium plates minus the ingredient nutrient broth. The optimum …

Molecular mechanisms underlying regulation of type III secretion system upstream of the master regulator HrpL in Erwinia amylovora
Erwinia amylovora, the causal agent of fire blight of apples and pears, is a necrogenic bacterium, whose virulence is dependent upon a functional hypersensitive response and pathogenicity (hrp)-type III secretion system (T3SS). It has been previously demonstrated that HrpL, an ECF sigma factor, is …

Role of Flagellar Motility in Apple Blossom Invasion and Tactic Response to Various Plant Nectar Extracts by Erwinia Amylovora
… (Nm22) and its motile revertant (MR22) of Erwinia amylovora were obtained after treating cells of the wild type (Isolate 110) with 0.3 M ethyl methanesulfonate. The pathogenicity of both isolates was similar with the wild type when inoculated to young shoots of apple seedlings. …

Status of streptomycin-resistant Erwinia amylovora in Illinois apple orchards and evaluation of alternative compounds to manage fire blight disease
… Fire blight disease, caused by the bacterium Erwinia amylovora, is a serious threat to apple production in Illinois and other Midwestern states. Streptomycin has been the most effective chemical for control of fire blight of pome fruits in Illinois, as well as nationwide. In 2008 and 2009, …

Identification and characterization of type III secretion inhibitors in Erwinia amylovora, the causal agent of fire blight of apple and pear
… of dollar losses around the world each year. Erwinia amylovora is the causative agent of fire blight. The type III secretion system (T3SS) and exopolysaccharide (EPS) amylovoran are two major yet separate virulence factors in E. amylovora. Current fire blight management mainly relies on …

Structural Studies of Protein-Small Molecule Interactions: Bombyx Mori Pheromone Binding Protein Specificity for Bombykol, and the Substrate Specificity of Pantocin A Biosynthetic Proteins
… pantocin A. This antibiotic is effective against Erwinia amylovora, the pathogen that causes fire blight disease. The functional form of the substrate was explored through genetic manipulation of the biosynthetic pathway that produces pantocin A.

Environmental bacteriophages infecting Dickeya and Serratia species: receptors and diversity
… study, but is more closely related to phages of Erwinia amylovora. A subset of the Ackermannviridae family phages were shown to be capable of facilitating transduction. This makes them unsuitable for use in the environment due to the risk of deleterious horizontal gene transfer. This is also true …
