Nuclear cycle of Saprolegnia ferax.
The mitotic nuclear (equivalent to cell) cycle of the oomycete fungus, Saprolegnia ferax, was analysed by quantitative serial-section electron microscopy of hyphal nuclear populations synchronized by inhibition of DNA synthesis by fluorodeoxyuridine (FdUrd). Following telophase and karyokinesis, kinetochore mitrotubules persist into G1 stage as a single group of approximately 42 per nucleus (2n...
متن کاملBehavior of kinetochores during mitosis in the fungus Saprolegnia ferax
In rapidly growing hyphae of Saprolegnia ferax, all nuclei contain arrays of kinetochore microtubules, which suggests that the nuclei are all in various phases of mitosis, with no apparent interphase. In prophase nuclei, kinetochore microtubules form a single, hemispherical array adjacent to the centrioles. This array separates into two similar arrays after centriole replication. The two arrays...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Cytoskeletal regulation of ion channel distribution in the tip-growing organism Saprolegnia ferax.
Growing hyphal tips of the oomycete Saprolegnia ferax possess a tip-high gradient of stretch-activated ion channels permeable to calcium. These mechanosensitive channels appear to play a direct role in the polarized tip growth process. Treatment of S. ferax hyphae with cytochalasin E leads to the disruption of plasmalemma-associated, peripheral cytoplasmic actin populations and altered morpholo...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
