Summary The intact yeast phase spores of Ophiostoma ulmi and O. novo-ulmi isolates were analysed by matrix-assisted-laser-desorption/ionization time-of-flight/time-of-flight mass spectrometry. The results clearly showed that isolates of O. ulmi and O

Summary Steady-state gene expression was compared between Dutch elm disease (DED)-susceptible Ulmus americana and DED-resistant U. pumila callus, leaf midrib, root and inner bark tissues. Stress-related cDNAs including phenylalanine ammonia-lyase (PA

Summary This study examined in vivo gene expression associated with the colonization of Dutch elm disease-susceptible Ulmus americana by H175, an aggressive strain of Ophiostoma novo-ulmi Brasier. Stress-related genes encoding phenylalanine ammonia-l

Summary This paper describes the chemical and biochemical properties of exopolysaccharides (EPS) produced by Ophiostoma ulmi and O. novo-ulmi isolates, the Dutch elm disease (DED) fungi. Some of EPS have been considered as pathogenicity factor in the

Isolates of Cylindrocladium floridanum obtained from diseased roots of white and black spruce seedlings and surrounding soil in bareroot nurseries in Ontario, Minnesota and Wisconsin area were compared by mitochondrial DNA (mtDNA) and ribosomal DNA (

We determined the distribution of root weevil larvae feeding on the roots of young ornamental conifers in field studies using a new non-destructive sampling technique. Most root weevil larvae fed on the roots during summer, fall, and late spring with

Field and laboratory studies were undertaken in southern Ontario to gain bionomical information on the adult strawberry root weevil (Otiorhynchus ovatus), a pest of ornamental conifer trees in nurseries. Emergence of overwintering adults began on 3 J

The lethal and mutagenic effects of ultraviolet (uv) irradiation on Ophiostoma ulmi sensu lato were tested. Exposure to uv rays increased the frequency at which benomyl-resistant mutants were recovered in five wild-type strains representing the non-a
