CONTENT OF 70 kDa STRESS PROTEIN DURING ACCLIMATION OF MUSSEL MYTILUS EDULIS L. TO LOW SALINITY.

ABSTRACT

The paper deals with the dynamics of stress-proteins content in gill epithelium of bivalved mollusks Mytilus edulis in the course of their phenotypic adaptation to the changes of environmental salinity. It has been shown that in low salinity (10 ‰) causing the work of «isolating reflex¼, the induction of stress proteins from HSP70 family comes on the 5th day of the acclimation. Parallel measurements of the mussels extravisceral liquid osmolarity have shown that the signal for stress-protein induction in these mollusks is the osmolarity of their inner medium, but not the salinity of marine water outside.
