Biotrophic fungal interaction with host plants involve alterations in host metabolism in favour of the fungus, characteristic of perturbations in the levels of plant growth regulators. Pyrenopeziza brassicae mycelia, culture filtrate and spore extracts contained zeatin riboside and iso-pentenyladenisine-type cytokinins as determined using HPLC-ELISA. The significance of cytokinin synthesis by P. brassicae in relation to infection of host plant tissue is discussed.
