Abstract

The Saccharomyces cerevisiae spore wall is a multilaminar coat that surrounds individual spores and protects them from environmental insult. Scanning electron microscopy reveals that the four spores of an ascus are connected by interspore bridges. Transmission electron microscopy of spores indicates that these bridges are continuous with the outer layers of the spore wall. In chs3 mutants, which lack the chitosan and dityrosine layers of the spore wall, bridges are absent. By contrast, in dit1 mutants, which lack only the dityrosine layer, bridges are present, suggesting that the bridges may be composed of chitosan. Interspore bridges are shown to be necessary to hold spores together after release from the ascus. A function for these bridges in the maintenance of heterozygous markers in a homothallic yeast population is proposed.
