Molecular dissection of fungal phytopathogenicity
Article Abstract:
Phytopathogenic effects of fungi in plants proceed through various processes for different fungi, and targeted gene disruption helps identify the genes responsible for disease induction and their properties. The fungi secrete enzymes to degrade plant cell walls and cuticles and toxins for the detoxification of antifungal substances in the plants. Alleles of one of the mating type loci in the fungus Ustilago maydis are important for the pathogenesis of the fungus. Use of 'black box' methods of fungal gene analysis and mutant characterization may enable a better understanding of the fungal pathogenesis.

A novel quantitative mating assay for the fungal pathogen Cryptococcus neoformans provides insight into signaling pathways responding to nutrients and temperature
Article Abstract:
A study was conducted to characterize a quantitative mating assay that describes the efficiency of signaling pathways responding to nutrients and temperature associated with Cryptococcus neoformans. The mating frequency of JEC43 cells was determined by the number of unmated cells from a mating mixture while the mating frequency was represented as a function of unrecovered JEC43 cells. Results suggested the possibility that a G-protein may influence the regulation of cAMP levels.

Monoclonal antibodies as probes for fungal wall structure during morphogenesis
Article Abstract:
Neurospora crassa, a fungus with a well-characterized wall biochemistry, was used to develop procedures for the isolation of mAbs specific probes for insoluble antigens. Its usefulness in investigations of wall architecture was also analyzed. Results reveal that epitopes of S4D1, S3B3 and S1E5 monoclonal antibodies are present within the inner layers of the walls of conidia and hyphae of N. crassa.
