Organelle inheritance in the yeast cell cycle.

Cell proliferation requires the inheritance of subcellular organelles, yet little is known of the molecular basis of this essential process. Recent microscopy studies of the yeast Saccharomyces cerevisiae have characterized the cellular distribution of mitochondria, vacuoles and elements of the endoplasmic reticulum and Golgi complex. In addition, genetic and microscopical approaches have allowed the isolation and analysis of mutants defective in the inheritance of mitochondria and vacuoles. These investigations are leading to the identification of molecular components mediating the movement of organelles into daughter cells and have revealed that the inheritance of organelles is coordinated with other events of the cell division cycle.
