Study on asexually transgenerational alteration in the rotifer

点击翻译按钮获取中文摘要

Extrinsic moderate oxidation was found to enhance the rotifer's ability to survive under lethal oxidative condition, and some molecules such as peroxidase, serine protease, and unidentified enzyme were identified to contribute to the phenomenon. The project has also established a reliable method to evaluate the oxidative stress tolerance, and revealed the species-specific tolerance between temperate and tropic Brachionus species. Temperature was found to cause transgenerational alteration in not only life history parameters, but also unidentified physiological condition which may determine the offspring quality.
