Previously, it was reported that a newly isolated microbial culture, Clavibacter sp. strain ALA2, produced trihydroxy unsaturated fatty acids, diepxoy bicyclic fatty acids, and tetrahydroxyfuranyl fatty acids (THFAs) from linoleic acid (C. T. Hou, J. Am. Oil Chem. Soc. 73:1359-1362, 1996; C. T. Hou and R. J. Forman III, J. Ind. Microbiol. Biotechnol. 24:275-276, 2000; C. T. Hou, H. Gardner, and...

Polyamine patterns of 75 strains of actinobacteria belonging to the genera Agrococcus, Agromyces, Aureobacterium, Brevibacterium, Cluvibacter, Corynebacterium, Curtobacterium, Microbacterium, Rathayibacter, and Tsukamurellu were analyzed in order to investigate the suitability of this approach for differentiation within this group. The results revealed that the overall polyamine contents differ...

The antibacterial activity of leaf and root ethanolic extracts as well as crude alkaloids and flavonoids from both the parts of Rhus succedanea were carried against bacterial strains viz. Staphylococcus aureus, Clavibacter michiganensis, Proteus vulgaris and Xanthomonas spp. The antibacterial activity was carried out on nutrient agar medium using disk diffusion method. The flavonoid fraction of...

Accurate and rapid detection of bacterial plant pathogen is the first step toward disease management and prevention of pathogen spread. Bacterial plant pathogens Clavibacter michiganensis subsp. nebraskensis (Cmn), Pantoea stewartii subsp. stewartii (Pss), and Rathayibacter tritici (Rt) cause Goss's bacterial wilt and blight of maize, Stewart's wilt of maize and spike blight of wheat and barley...

The tomato pathogen Clavibacter michiganensis subsp. michiganensis NCPPB382, which causes bacterial wilt, harbors two plasmids pCM1 (27.5 kb) and pCM2 (72 kb). After curing of the plasmids, bacterial derivatives were still proficient in the ability to colonize the host plant and in the production of exopolysaccharides but exhibited a reduced virulence. When one of the two plasmids is lost, ther...

Clavibacter michiganensis, subsp. michiganensis is a Gram-positive plant pathogen infecting tomato (Solanum lycopersicum). Despite a considerable economic importance due to significant losses of infected plants and fruits, knowledge about virulence factors of C. michiganensis subsp. michiganensis and host-pathogen interactions on a molecular level are rather limited. In the study presented here...

The impact of phytopathogenic microorganisms in several crops causes significant losses agrifood industry, spoilage throughout food chain and storage. Nanoparticles plant extracts have been highlighted by their antimicrobial properties applied packaging, agriculture, drug delivery systems other medical approaches. Over the past few years, this group studied application ZnO nanoparticles agroind...
