Reproductive cycle and temperature-related differences in baseline levels of HSP70 and metallothioneins in wild oyster populations of Crassostrea gigas
International audience Heat Shock Protein 70 (HSP70) are generalist stress proteins expressed in response to numerous environmental stresses. However, the baselines of these constitutive proteins are still unknown in many organisms and in particular marine intertidal species such as the Pacific oyst...
