Abstract Heat shock proteins (Hsps) have dual functions, participating in both the stress response and a broad range of developmental processes. At physiological temperatures, it has been demonstrated in deuterostomes (vertebrates) and ecdysozoans (insects) that Hsps are expressed in tissues that are undergoing differentiation and morphogenesis. Here we investigate the developmental expression of Hsp70, Hsp90 and their regulatory transcription factor heat shock transcription factor (HSF) in the marine gastropod Haliotis asinina, a representative of the 3rd major lineage of bilaterian animals, the Lophotrochozoa. HasHsp70, Hasffip90 and HasHSF are maternally expressed in H. asinina and are progressively restricted to the micromere lineage during cleavage. During larval morphogenesis, they are expressed in unique and overlapping patterns in the prototroch, foot, and mantle. Hsp expression peaked in these tissues during periods of cell differentiation and morphogenesis, returning to lower levels after morphogenesis was complete. These patterns of Hsp and HSF expression in H. asinina are akin to those observed in ecdysozoans and deuterostomes, with Hsps being activated in cells and tissues undergoing morphogenesis.
