Iron-dependent regulation of gene expression in Corynebacterium pseudotuberculosis

The results presented in this thesis confirm the importance of iron to C. pseudotuberculosis, and reveal the existence of an iron-dependent regulator which is involved in regulating the expression of multiple target genes.

Presence of Quorum-Sensing-Mediated Gene Regulation in Pathogenic Ice-Nucleation-Active (INA) Bacteria

Evidence that pathogenic ice-nucleation bacteria with inducible INA produce QS signals that in other bacteria have been shown to be in the control of genes of importance for pathogenicity is provided.

Commercialization of Plant Systemic Defense Activation: Theory, Problems and Successes

Although the activation of systemic resistance has been demonstrated reproducibly in the laboratory for many plant species, utilizing a wide range of activating materials, it is not yet a proven technology widely accepted in commerce.



Quorum sensing in bacteria: the LuxR-LuxI family of cell density-responsive transcriptional regulators

How the marine luminescent bacterium V. fischeri uses the LuxR and LuxI proteins for intercellular communication is reviewed and a newly discovered family of LuxRand LuxI homologs in diverse bacterial species is described.

Engineered detoxification confers resistance against a pathogenic bacterium

It is shown that genetic modification to express a toxin-resistance gene can confer resistance to both disease symptoms and multiplication of a toxigenic pathogen in its host.

Plants genetically modified to produce N-acylhomoserine lactones communicate with bacteria

The ability to generate bacterial quorum-sensing signaling molecules in the plant offers novel opportunities for disease control and for manipulating plant/microbe interactions.

Plant-pathogen microevolution: molecular basis for the origin of a fungal disease in maize.

It is demonstrated that resistance to C. carbonum race 1 is the wild-type condition in maize, and results suggest that the Hm-encoded resistance is of ancient origin and probably is conserved in all grasses.
