A self-inhibitor in uredospores of the coffee rust fungus :
Uredospores of the coffee rust fungus (Hemileia vastatrix) were shown to contain a potent self-inhibitor. The compound was extracted from the spores with water, partitioned into ether, and chromatographed on thin-layer plates of silica gel. The compound had an Rf equal 0.3 in a benzene:ether solvent (80:20, v/v) system, and the extract from 2 mg of spores was required to obtain the ED50. Neither of the known self-inhibitors from spores of two other species of rust fungi (Puccinia spp. and Uromyces spp.) effectively inhibited germination of H. vastatrix uredospores
