Cytokinesis involves temporally and spatially coordinated action of the cell cycle, cytoskeletal and membrane systems to achieve separation of daughter cells. The septation initiation network (SIN) and mitotic exit network (MEN) signaling pathways regulate cytokinesis and mitotic exit in the yeasts Schizosaccharomyces pombe and Saccharomyces cerevisiae,(More)

Faithful chromosome segregation depends on the precise timing of chromatid separation, which is enforced by checkpoint signals generated at kinetochores. Here, we provide evidence that the C-terminal domain (CTD) of DNA topoisomerase IIα (Topo II) provides a novel function at inner centromeres of kinetochores in mitosis. We find that the yeast CTD is(More)
Anthocyanins are a class of flavonoids that are responsible for the pigmentation of red potato periderm. The cDNAs of two genes were cloned from ‘Norland’ periderm and, based on their sequence similarity to genes in various databases, were identified as the anthocyanin biosynthetic genes for leucoanthocyanidin dioxygenase (EC 1.14.11.19) and UDP glucose:(More)
