Hsp70 gene expansions in the scallop Patinopecten yessoensis and their expression regulation after exposure to the toxic dinoflagellate Alexandrium catenella

A full set of 61 PyHsp70 genes was characterized in the P. yessoensis genome.

Extensive expansion of Hsp70 genes occurred independently in the bivalve lineages.

PyHsp70s up-regulated after A. catenella exposure were all from the bivalve-specific expanded Hspa12 sub-family.

Responses to toxic stress in scallop may have arisen through adaptive evolution of tandem duplication of PyHsp70 genes.
