Abstract |
The effects of increasing salinity on the ultrastructural morphology of the lysosomal-vacuolar system in digestive cells of the common mussel M. Edulis were investigated in order to relate structural changes to previous biochemical and cytochemical observations. After 3 h of increased salinity, from 21 to 35 ppt. the digestive cells showed an increase in numbers of heterolysosomes. It is concluded that increasing salinity from 21 to 35 ppt. stimulates the lysosomal-vacuolar system, as a result of autophagocytosis or apoptosis. |
