Pathogenesis of apple by the facultative parasite Penicillium expansum was critically dependent upon certain physiological events during the primary stages of spore germination. A comparison of two prototrophic isogenic strains of the fungus, one of

The screening in vitro of large numbers of conidia of Venturia inaequalis against the selection pressure of dodine revealed a spontaneous mutation rate to dodine tolerance of about 1 in 106 conidia screened. Mutants cultured as mycelial disks grew 53

Symptom expression in tomatoes infected with isolates of tobacco mosaic virus (TMV) was profoundly influenced by temperature, day-length and light intensity. We suggest that symptoms such as fern-leaf and distortion, which result from the interplay o

Over 100,000 prototrophic survivors from ultraviolet-irradiated stock were screened for pathogenicity on apple fruits. Of these, seven showed altered pathogenic capacity when compared with the wild type, five having reduced virulence and two being co

Two hundred and nine isolates of tobacco mosaic virus (TMV) were collected from the spring and fall greenhouse crops, and the field crop of Southern Ontario. Strains of the virus were identified on a series of differentials which included Pelham's fo

A simplified procedure for demonstrating the parasexual cycle is presented. The sequence of laboratory experiments, using a conidial strain rather than an ascosporic strain of Aspergillus nidulans, requires a minimum of time and materials, and can be

The integrity of the local-lesion technique in producing genetically homogeneous isolates of tobacco mosaic virus from Nicotiana glutinosa has been verified using strains doubly labeled with genetic markers governing symptomatology and host range.
