| 拥有强大的渗透压调节能力对广盐性鱼类的生存至关重要。目前，关于鱼类渗透压调节机制已有不少研究，但均存在较大的局限性。本文从广盐性鱼类渗透压信号转导机制、渗透胁迫的细胞调控机制、渗透调控的内分泌调节机制和无机离子通道和转运蛋白介导的渗透调控等方面对广盐性鱼类的渗透压适应性和生理可塑性机制进行分析，以期从分子、细胞、通路和生理等层次初步探索广盐性鱼类盐度胁迫后的可塑性表型变化和不同盐度条件下的应答机制，为广盐性鱼类的渗透压调节机制的深入研究奠定基础。对广盐性鱼类渗透压适应性与生理可塑性机制研究，有助于研究其环境适应机理，促进野生鱼种的人工化养殖以及新品种的育种从而提高经济效益、社会效益和生态效益，对促进水产养殖学进步以及养殖业的发展具有重要意义，同时，为研究广盐性鱼类的渗透压调节机制开辟新的研究方向。 |

| Abstract: |
| It has a strong ability to regulate osmotic pressure is essential to survive for euryhaline. So far, there are many studies on osmoregulation mechanisms of euryhaline, but limitation. Analysis on osmotic pressure signal transduction mechanism, cell regulation mechanism under osmotic stress, endocrine regulation mechanism under osmotic stress and osmoregulation meditated by inorganic ion channels and transporters reveal preliminary response mechanisms and divergence in phenotypic plasticity in the molecular, cellular, pathway and physiology levels, aiming to lay the foundation for further study of the osmoregulation mechanism of euryhaline. Studies on the mechanism of osmotic pressure adaptability and physiological plasticity of euryhaline are helpful to study its environmental adaptation mechanism, promote the artificial breeding of wild species and breeding of new species to improve the economic, social and ecological benefits, and it plays an important role in promoting the advancement of ichthyology and aquaculture science as well as the development of world aquaculture industry and opens up a new research field for studying the mechanism of osmoregulation of euryhaline. |
