Physiological characteristics of <em>Microcyclus ulei</em> (P. Henn.) V.ARX. – a fungal pathogen of the cyanogenic host <em>Hevea brasiliensis</em>

The ascomycete Microcyclus ulei causes premature leaf shedding of the rubber tree, Hevea brasiliensis. During the development of this biotrophic fungus in the tissues of infected leaves HCN is liberated from the lesions. Despite high HCN concentrations in the leaf tissue the pathogenic fungus develo...
