| 摘 要： | 耐盐碱鱼类生理和分子适应机制的解析,是培育适于中、高碱度盐碱水域增养殖种的先决条件。围绕世界各国适于中、高碱度盐碱湖泊养殖的鱼类代表种,从组织结构的微观调整、血液离子和渗透压调节、特殊氨氮代谢的形成、酸碱调节、激素调节以及基因组特定区域的选择性表达和适应等方面进行归纳总结,提出耐盐碱鱼类的盐碱适应机制具有多样、复杂、系统性强的特点。建议借助先进的基因功能研究方法,系统整合耐盐碱鱼类在生理、表型、行为和各种组学的遗传信息,将相关性探索研究拓展到基因水平的因果关系确定,推动耐碱鱼类的分子遗传基础与分子适应性进化机制的研究进程。

| Abstract: | Aquaculture is one of important ways to utilize alkaline-saline water or land effectively. However, knowing about the physiological and molecular mechanisms related to alkaline and saline adaptation is the prerequisite to breed varieties for aquaculture with mid or high alkalinity and salinity water. This paper summarized the advances of physiological and molecular mechanisms in several representative fish species inhabiting in alkaline and saline lakes around the world, including tissues micro-changing, blood ions and osmoregulation, ammonia and urea metabolism, acid-base regulation, hormone regulation and genome adaptations. Based on these latest advances, we considered the alkaline-saline tolerant fish having strong phenotypic plasticity, complexity and integrity due to their extreme hypersaline soda habitats. It is suggested that the research of correlation exploration should be extended to the determination of causality at gene level through systematically integrating the information of alkaline and saline fish in physiology, phenotype, behavior and various omics, which will promote the research process of molecular genetic basis and evolutionary mechanism of alkaline and saline tolerant fish. |
