Production of heat shock protein is independent of cell cycle blockage in the yeast Saccharomyces cerevisiae.

In response to certain environmental stresses, cells display a response characterized by the production of heat shock proteins. In this study we showed that blockage of cells of the yeast Saccharomyces cerevisiae at specific points in the mitotic cell cycle was not in itself a stress that induced the production of heat shock proteins. Nevertheless, cell cycle blockage did not preclude a normal heat shock response in arrested cells subjected to elevated temperatures.
