Ustilago maydis - valuable model system for the study of fungal dimorphism and virulence
Article Abstract:
Ustilago maydis, a phytopathogenic fungus, is discussed as a good model system for study of fungal dimorphism and virulence in this review article. Topics include its life cycle, genetic control of mating and pathogenesis, signaling and how it affects morphology/virulence, identification of virulence genes, the and generation of avirulent mutants by plasmid insertion and isolation of pathogenicity genes by their specific expression pattern. The existence of one master control locus for pathogenicity allowing a top-down approach is also covered.

Avirulence genes in plant-pathogenic bacteria: signals or weapons?
Article Abstract:
Microbial avirulence genes are virulence factors that are introduced by the bacterial hypersensitive reaction pathogenicity (Hrp) secretion system into susceptible plant cells. The function of avirulence genes from plant-pathogenic bacteria exhibit host-specific roles in pathogenicity as a virulence factor. However, plants have evolved to recognize microbial virulence factors which trigger programmed cell death in infected plant cells.
