Myosin II is an essential component of the contractile ring that divides the cell during cytokinesis. Previous work showed that regulatory light chain (RLC) phosphorylation is required for localization of myosin at the cellular equator ( 1, 2 ). However, the molecular mechanisms that concentrate...
The establishment of Drosophila embryonic dorsal-ventral (DV) polarity relies on serine proteolytic activity in the perivitelline space between the embryonic membrane and the eggshell ( 1 ). Gastrulation Defective cleaves and activates Snake, which processes and activates Easter, which cleaves...
Biodiversity 2010: Projects in Borneo are providing examples of rainforest management. Michael Gross reports.
Background In Drosophila epithelial cells, specification and maintenance of the zonula adherens (za) is crucial to ensure epithelial tissue integrity. This depends on the intertwined function of Bazooka (Baz), Par6-DaPKC, and the Crumbs (Crb)-Stardust (Sdt)-PATJ complex. However, the detailed...
Upon seed germination, apical meristems grow as cell division prevails over differentiation and reach their final size when division and differentiation reach a balance. In the Arabidopsis root meristem, this balance results from the interaction between cytokinin (promoting differentiation) (...
Chimpanzees make lethal coalitionary attacks on members of other groups (1) . This behavior generates considerable attention because it resembles lethal intergroup raiding in humans (2) . Similarities are nevertheless difficult to evaluate because the function of lethal intergroup aggression by...
Biodiversity 2010: The UN marked this year with a special day this month, but the targets it set two decades ago to stem species losses have proved disappointing and one group of animals highlights the range of problems facing conservationists. Nigel Williams reports.
A new eucrustacean arthropod, Wujicaris muelleri gen. et sp. nov, is represented by a Lower Cambrian early metanauplius of strikingly modern morphology despite being the oldest known fossil of such an early immature crustacean larva. The morphology of the metanauplius closely mirrors that of...
DNA replication in eukaryotic cells is tightly regulated to ensure that each origin fires just once. Activation of the replicative DNA helicase (Mcm2–7) during S phase requires the recruitment of Cdc45 and GINS into a CMG complex (1) . In yeast, this step proceeds via the formation of a...
