in order to evaluate the effects of drought stress and planting method on some physiological and biochemical characteristics of two chickpea cultivars (cicer arietinum l.) an experiment was conducted at the research station of college of agriculture, shiraz university using a split factorial based on randomized complete block design in four replications. the main factor was stopping irrigation ...

in order to improve the efficiency of irrigation systems and investigate their impact on the pest population levels, furrow and sprinkler irrigation systems were compared in sugar beet fields. in this study, three different fields were chosen and irrigated by one of the furrow, classic and center pivot irrigation systems.  in each field, 20 plots were randomly selected of which 10 plots were ma...

Cell division is achieved by a plasma membrane furrow that must ingress between the segregating chromosomes during anaphase [1-3]. The force that drives furrow ingression is generated by the actomyosin cytoskeleton, which is linked to the membrane by an as yet undefined molecular mechanism. A key component of the membrane furrow is anillin. Upon targeting to the furrow through its pleckstrin ho...

The Drosophila embryo undergoes a developmental transition in the blastoderm stage switching from syncytial to cellular development. The cleavage furrow, which encloses nuclei into cells, is a prominent morphological feature of this transition. It is not clear how the pattern of the furrow array is defined and how zygotic genes trigger the formation and invagination of interphase furrows. A key...

Although Aurora B is important in cleavage furrow ingression and completion during cytokinesis, the mechanism by which kinase activity is targeted to the cleavage furrow and the molecule(s) responsible for this process have remained elusive. Here, we demonstrate that an essential mitotic kinesin MKlp2 requires myosin-II for its localization to the equatorial cortex, and this event is required t...

In the eggs of the newt, Triturus pyrrhogaster, 2 separate factors are recognized which take part in cleavage furrow formation. (1) The inductive capacity for the furrow formation by the cytoplasm lying under the cortex along the cleavage furrow (FIC); and (2) the reactivity of the overlying cortex to form a furrow in response to FIC. (1) FIC. The inductive capacity is shown by the fact that FI...
