Culture filtrates of Alternaria brassicicola (Schw.) Wilts, were found to be toxic to secondary embryoids of Brassica napus ssp. oleifera (Metzg.) Sinsk. The culture filtrates were partially purified and added to tissue culture media to produce a sel

Studies on the effect of culture extracts were found to throw a new light on the reproductive strat- egies of fungi. It was confirmed that extracts of mated cultures of Pyrenopeziza brassicae stimulated the de? velopment of ascocarp-like structures a

A polyclonal, enzyme-linked immunosorbent assay (ELISA) of Phytophthora infestans has been developed for use in the determination of fungal biomass during the early stages of infection of tuber discs of Solanum tuberosum. By optimizing the dilution o

As a basis for devising an in vitro screening programme, culture conditions were optimized so that tissue cultures from two resistant cultivars of Brassica napus ssp. oleifera (Mikado, Bienvenu) and two susceptible cultivars (Lesira, Ceres) could be

A simplified method for the quantitative assessment of the fungal lipid ergosterol was used to assess the levels of infection in tissue cultures of oilseed rape (Brassica napus ssp. oleifera) inoculated with Leptosphaeria maculans. The growth of L. m

A detached cotyledon pathogenicity test was devised for the isolation of UV-induced mutants of the hemibiotrophie ascomycete pathogen of Brassica spp., Pyrenopeziza brassicae defective in pathogenicity determinants. At least 95 % of cotyledons of sui

Conventional plant breeding for resistance to pathogens, although successful, is in many cases still too slow to keep pace with pathogen adaptation, and suffers from the lack of genetic variability in cultivated varieties. Phytotoxins, because of the
