Yeast filamentous actin (F-actin) exists mainly as patches and cables. Previously, we investigated the behavior of F-actin during sporulation of Zygosaccharomyces rouxii and found a novel actin ring localized around the spore periphery in zygotic asci at a late stage of sporulation. To clarify whether the actin rings are also formed in sporulation in the model yeast Saccharomyces cerevisiae, we observed the distribution of F-actin in sporulating S. cerevisiae by rhodamine-phalloidin staining and confocal laser scanning microscopy. Ringlike actin structures were detected at the peripheral regions of S. cerevisiae spores in globose asci. When asci of S. cerevisiae were induced to become zygotic, actin rings were more obvious than those in globose asci. These results indicate that S. cerevisiae forms characteristic actin ring structures at a late stage of sporulation, similarly to Z. rouxii.
