Host range and molecular phylogenies of the soft rot enterobacterial genera pectobacterium and dickeya.
Phylogenetic analyses of sequences concatenated from regions of seven housekeeping genes from representatives of these genera demonstrated that Dickeya spp. Expand
A clp Gene Homologue Belonging to the Crp Gene Family Globally Regulates Lytic Enzyme Production, Antimicrobial Activity, and Biological Control Activity Expressed by Lysobacter enzymogenes Strain C3
Results indicate that clp is a global regulatory gene that controls biocontrol traits expressed by L. enzymogenes C3 and mutants of strain C3 affected in extracellular enzyme production were significantly affected in biological control of pythium damping-off of sugar beet and bipolaris leaf spot of tall fescue.

Dynamic regulation of GacA in type III secretion, pectinase gene expression, pellicle formation, and pathogenicity of Dickeya dadantii (Erwinia chrysanthemi 3937).
The nearly abolished systemic invasion ability of Ech137 suggests that GacA of D. dadantii is essential for the pathogenicity and systemic movement of the bacterium in S. ionantha. Expand
Characterization of a Chitinase Gene from Stenotrophomonas maltophilia Strain 34S1 and Its Involvement in Biological Control
Pairwise comparisons of each domain to the most closely related sequences found in database searches clearly demonstrated variation in gene sources and the species from which related sequences originated. Expand
Mutation of rpiA in Enterobacter cloacae decreases seed and root colonization and biocontrol of damping-off caused by Pythium ultimum on cucumber.
Experiments reported here indicate a key role for rpiA and possibly the pentose phosphate pathway in suppression of damping-off and colonization of subterranean portions of plants by E. cloacae. Expand
Occurrence of bacterial blight of fenugreek caused by Pseudomonas syringae pv. syringae and isolation of the pathogen from infested seed
The bacterium was isolated from a seed lot used in New Jersey that resulted in diseased plants, suggesting seed as the probable source of the pathogen. Expand
