摘要
鱼和虾类经常接触异常的水温、低溶氧量的水体、或高或低的盐度等不利生存的环境,在这些逆境胁迫下,生物有机体会特异开放一些基因的表达或提高某些特定蛋白的表达丰度,以度过难关。这些基因和蛋白质包括14-3-3基因、抗冻蛋白、热激蛋白和Na/K-ATPase酶等。同时,这些基因和产物对于人类研究生命的起源和进化、改良经济水生生物的品质及环境监测等都具有重要意义。
The abnormal temperature, low-disslved oxygen, and unsuitable osmotation in water body are all baleful to the marine organisms, such as fishes and shrimps. Being in the condition, the fish and shrimp will express some genes or increase the abundance of their productions accordingly, for example, the antifreeze proteins, heat shock proteins, Na/K-ATPase, 14-3- 3a,et al. All of above gene and their productions are useful to us for studying the evolution and genesis of lives, and improving the quality of some species and inspecting the environment.
