Transcellular ion currents in the water mold Achlya. Amino acid proton symport as a mechanism of current entry
Achlya, like other tip-growing organisms, generates an endogenous electrical current such that positive charge flows into the hyphal apex and exits from the trunk. The present study is concerned with the mechanism of current generation by hyphae growing in a defined, complete medium. The intensity of the current, measured in the extracellular medium with a vibrating probe, was unaffected by the...
متن کاملIon currents in embryo development.
Ion channels are proteins expressed in the plasma membrane of electrogenic cells. In the zygote and blastomeres of the developing embryo, electrical modifications result from ion currents that flow through these channels. This phenomenon implies that ion current activity exerts a specific developmental function, and plays a crucial role in signal transduction and the control of embryogenesis, f...
متن کاملTwo distinct distributions of F-actin are present in the hyphal apex of the oomycete Achlya bisexualis.
We show that two distinct distributions of F-actin are present in the hyphal apex of the oomycete Achlya bisexualis, that have been chemically fixed with a combination of methylglyoxal and formaldehyde and stained with Alexa phalloidin. In approximately one half of the hyphae examined, an F-actin depleted zone within the apical F-actin cap was observed. The remaining hyphae had a continuous api...
متن کاملTranscellular Water Flow Modulates Water Channel Exocytosis
Introduction The regulation of osmotic water permeability (Pf) by vasopressin (VP) in kidney collecting tubule involves the exocytic-endocytic trafficking of vesicles containing water channels between an intracellular compartment and apical plasma membrane. To examine effects of transcellular water flow on vesicle movement, Pf was measured with 1-s time resolution in the isolated perfused rabbi...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
