Effect of Autogamy on Cellular Sensitivity to Natural Ionizing Radiations and X-Rays.
Abstract
It is shown that, after autogamy, there is a large decrease of radiosensitivity of Paramecium aurelia to natural ionizing radiations or to X-rays. These modifications come in addition to the well known physiological changes induced by conjugation or autogamy in Paramecium. The origin of these modifications cannot be determined. Nevertheless, nuclear reorganisation involved by autogamy may explain the modifications of chromosome number may result in large fluctuation of radiosensitivity in many species. New investigations are in progress to try to determine the mechanism involved in cellular response to natural ionizing radiation. (Modified author abstract)
