Title
High-hydrostatic-pressure treatment impairs actin cables and budding in Saccharomyces cerevisiae
Abstract

We previously reported that the postgrowth of Escherichia coli K-12 after high-hydrostatic-pressure treatment (HPT) as moderate as 75 MPa for 30 min at 37°C induced the formation of elongated cells due to an HPT-induced disorder in FtsZ ring formation, which is essential for cell division. Because an FtsZ ring is known as a bacterial cytoskeleton, we examined the effect of HPT on a eukaryotic cytoskeleton, such as actin cables (long bundles of actin filaments), of Saccharomyces cerevisiae. We found that actin cables disappeared after HPT (100 MPa) and were not reorganized until 3.5 h of growth after HPT. As long as actin cables disappeared, budding did not start. We also demonstrated that the in vitro polymerization of actin monomers was highly sensitive to HPT.
