Oysters are notably susceptible to accumulating substantial amounts of cadmium (Cd), leading to food safety concerns, yet the molecular mechanisms are not fully understood. Previous study identified a significant correlation between polymorphisms in the Zip1 and Zip3 of Fujian oyster ( Crassostrea angulata ) and the levels of Cd accumulation. Zip1 and Zip3 , belonging to the Zip family, are primarily responsible for the cellul...
