Magallana

Magallana is a genus of true oysters (family Ostreidae)^[1] containing some of the most important oysters used for food. Species in this genus have been moved from Crassostrea after it was found to be paraphyletic.^[2][3]

Genetics

The genome of Magallana gigas has been recently sequenced ^[4] revealing an extensive set of genes that enable it to cope with environmental stresses.
