We have examined the feasibility of using array comparative genomic hybridization (aCGH) to explore intraspecific genetic variability at the genomic level in two pathogenic molds, Aspergillus fumigatus and Aspergillus flavus. Our analysis showed that strain-specific genes may comprise up to 2% of their genomes in comparison to isolates from different vegetative (heterokaryon) compatibility grou...

Fusarium oxysporum is an asexual fungal species that includes human and animal pathogens and a diverse range of nonpathogens. Pathogenic and nonpathogenic strains of this species can be distinguished from each other with pathogenicity tests, but not with morphological analysis or sexual compatibility studies. Substantial genetic diversity among isolates has led to the realization that F. oxyspo...

glomerella cingulata is the causal agent of anthracnose disease on citrus that attacks weakened trees. the sexual stage is rare in nature but can be produced in laboratory under certain conditions. sixty-seven single-spore isolates were selected from citrus in mazandaran province to be used in this study. isolates were cultured on ypss for investigating heterothallism and homothallism. to under...
