The integrity of spores formed by mutant strains of Dictyostelium discoideum lacking the major spore coat proteins, SP96, SP70, or SP60, was compared to that of wild-type strains. Single, double, and triple knock-out strains developed normally and produced spores which were indistinguishable from wild-type spores by light or electron microscopy. However, the mutant strains were susceptable to staining with the lectin, ricin A, which recognizes a galactose-rich polysaccharide that is normally… CONTINUE READING
