Accumulation, biochemical responses and changes in the redox proteome promoted by Ag and Cd in the burrowing bivalve Scrobicularia plana.

Silver (Ag) and cadmium (Cd) are non-essential metals that, as a result of natural processes and human activities, reach the aquatic environment where they interact with biota inducing potential toxic effects. To determine the biological effects of these metals on the endobenthic bivalve Scrobicularia plana, specimens were exposed to Ag and Cd at two concentrations, 5 and 50 μg∙L, for 7 days in a controlled microcosm system. The levels of the metals were measured in the seawater, sediments and clam tissues.

Constructing a de novo transcriptome and a reference proteome for the bivalve Scrobicularia plana: Comparative analysis of different assembly strategies and proteomic analysis.

Scrobicularia plana is a coastal and estuarine bivalve widely used in ecotoxicological studies. However, the underlying molecular mechanisms for S. plana pollutant responses are hardly known due to the lack of molecular databases.
