Abstract
AN explanation in nutritional terms of host, organ or tissue specificity of parasitic microorganisms has not received much attention although in some widely differing systems nutritional factors are clearly of paramount importance. Erythritol, asparagine and myoinositol are growth factors required by Brucella abortus, Brazilian strains of Pasteurella pestis and Rhodosticta quercina respectively. The presence or absence of these factors in their respective hosts, domestic animals, guinea-pigs and plum trees, determines their susceptibility or resistance to the appropriate parasite1–3. We report a fungal growth stimulant determining organ specificity of a fungal pathogen of plants.
