Screening of Ampelomyces quisqualis Isolates Hyperparasite on the Tobacco Powdery Mildew Fungus

2012 International Conference on Biomedical Engineering and Biotechnology, 2012
12 isolates of Ampelomyces quisqualis from different sources were in vitro inoculated to the center of the powdery mildew colonies on the diseased tobacco leaves, and two parameter values of pathogenicity scales and virulence of Ampelomyces isolates were obtained by counting the numbers of pycnidia and by measuring mycoparasited area on powdery mildew ...

The chsA gene, encoding a class-I chitin synthase from Ampelomyces quisqualis

Gene, 1996
Degenerate oligodeoxyribonucleotide primers, designed on the basis of conserved regions of the chitin synthase gene family, were used to amplify a fragment of the Ampelomyces quisqualis (Aq) chsA gene. Subsequently, the PCR product was used as a probe in order to identify and isolate genomic clones harboring the entire chsA gene.

Scanning electron microscopy of the ontogeny of Ampelomyces quisqualis pycnidia

Canadian Journal of Microbiology, 1985
Observations on Ampelomyces quisqualis disclosed that the pycnidium may originate either from one cell of a single pycnidiospore, or from one hyphal cell. In the first case the pycnidiospore becomes two celled and swollen and a profuse germination of one of the two swollen spore cells can be observed.
