Abstract

The main cause of yeast cell death in moderate heat shock is increased production of reactive oxygen species (ROS). Mitochondria make the main contribution to the production of ROS under thermal exposure. Increased mitochondrial membrane potential (MMP) is the reason for increased ROS production. Thus, increased MMP runs the program the death of yeast cells upon moderate heat shock. At the same time, the increase of MMP during mild heat stress activate a protective program aimed at increasing resistance.
