Cytokinesis in early zebrafish embryos involves coordinated changes in the f-actin- and microtubule-based cytoskeleton, and the recruitment of adhesion junction components to the furrow. We show that exposure to inhibitors of non-muscle myosin II function does not affect furrow ingression during the early cleavage cycles but interferes with the recruitment of pericleavage f-actin and cortical b...

During cytokinesis, cleavage furrow invagination requires an actomyosin-based contractile ring and addition of new membrane. Little is known about how this actin and membrane traffic to the cleavage furrow. We address this through live analysis of fluorescently tagged vesicles in postcellularized Drosophila melanogaster embryos. We find that during cytokinesis, F-actin and membrane are targeted...

The nutritional status, juice quality and sugar production of sugarcane varieties RB867515 RB92579 were evaluated in the cane-plant cycle, as a function magnesium doses applied at bottom planting furrow. study, installed soil with Mg content equal to 0.61 cmolc dm-3, was conducted an experimental design randomized blocks four replications. study 2 x 5 factorial: two varieties: RB92579, five mag...

Cytokinesis by contraction of the base of the cleavage furrow and the dependence of the position of the future furrow on the arrangement of cytoplasm under it have been demonstrated at relatively earlier stages of cleavage in amphibian eggs. The following experiments and observations on dividing eggs of the newt Cynops pyrrhogaster indicated the presence of the contracting force at the base of ...

The ridge–furrow mulching system with plastic film (RFMS) has been widely used in semi-arid areas order to improve soil water and heat conditions, crop yields use efficiency. It is of practical significance study the effect ridge types on optimize measures effectiveness furrow system. To clarify combined beneath influence morphology it, field experiments were conducted three treatments, includi...

RhoA controls cleavage furrow formation during cell division, but whether RhoA suffices to orchestrate spatiotemporal dynamics of furrow formation is unknown. In this issue, Wagner and Goltzer (2016. J. Cell Biol http://dx.doi.org/10.1083/jcb.201603025) show that RhoA activity can induce furrow formation in all cell cortex positions and cell cycle phases.
