Here, we report our studies to investigate the unknown underlying mechanisms of the observed responses. We tested the hypothesis that turbulence could alter the correct assemblage of microtubules composing the mitotic spindle involved in the chromosome segregation during the dinomitosis. In shaking experiments performed on Akashiwo sanguinea, Prorocentrum micans and Oxyrrhis marina, microtubules were visualized through a combination of inmunocytochemistry (using anti-tubulin monoclonal antibodies) Confocal Fluorescent Laser Microscopy. Each species showed particular organizations of the nuclear, microtubular and other mitotic elements under still conditions. These mitotic organizations appeared unmodified by turbulence. Thus, our results did not provide evidences to support the microtubule hypothesis. Some alternative hypotheses also linked to the microtubular organization in the cell are suggested Peer Reviewed 2013-08-05T06:29:51Z 2013-08-05T06:29:51Z 2010-11 2013-08-05T06:29:52Z comunicación de congreso http://purl.org/coar/resource_type/c_5794 14th International Conference on Harmful Algae.
