44. Comparison of ATPase-Encoding Type III Secretion System hrcN Genes in Biocontrol Fluorescent Pseudomonads and in Phytopathogenic Proteobacteria
Type III protein secretion systems play a key role in the virulence of many pathogenic proteobacteria, but they also occur in nonpathogenic, plant-associated bacteria. Certain type III protein secretion genes (e.g., hrcC) have been found in Pseudomonas sp. strain SBW25 (and other biocontrol pseudomonads), but other type III protein secretion genes, such as t

45. β-Glucosidase Activity in Phytopathogenic Bacteria
Most of 58 isolates of phytopathogenic and related bacteria comprising 24 species in the genera Agrobacterium, Erwinia, Corynebacterium, Pseudomonas, and Xanthomonas exhibited β-glucosidase activity, especially the gall-nonforming pathogenic pseudomonads and soft rot organisms. The gall-forming pseudomonads and P. fluorescens exhibited no β-glucosidase act

46. Use of Immunogold Labelling with Scanning Electron Microscopy To Identify Phytopathogenic Bacteria on Leaf Surfaces †
Scanning electron microscopy coupled with high-resolution back-scattered electron imaging was used to detect gold-labelled specific immunoglobulins attached to epiphytic bacteria. Strains of Xanthomonas citri and X. campestris pv. citrumelo were specifically identified on grapefruit leaf surfaces when labelled with homologous gold-labelled immunoglobulins.

47. Antagonism of Lactic Acid Bacteria against Phytopathogenic Bacteria
A variety of lactic acid bacteria, isolated from plant surfaces and plant-associated products, were found to be antagonistic to test strains of the phytopathogens Xanthomonas campestris, Erwinia carotovora, and Pseudomonas syringae. Effective “in vitro” inhibition was found both on agar plates and in broth cultures. In pot trials, treatment of bean plant

48. Susceptibility of Phytopathogenic Bacteria to Wheat Purothionins In Vitro
Purothionins are basic polypeptides with antimicrobial properties that are present in the endosperm of wheat and other cereal species. Susceptibility to wheat purothionins among phytopathogenic bacteria of the genera Pseudomonas, Xanthomonas, Agrobacterium, Erwinia, and Corynebacterium has been investigated. Sensitive strains have been found in all of these
