Summary

The ontogeny and localization of the γ crystallins in Discoglossus pictus lens development has been determined. Using antibody specific for amphibian γ crystallins in the immunofluorescence technique, it was found that γ crystallins first appear in primary lens fibre cells in the lens rudiment, and continue to be restricted to the fibre area as lens development progresses. Thus the role of γ crystallins as indicators of a differentiated state remains constant in amphibian evolution, having been demonstrated in the most archaic anuran superfamily, as well as in others more recently evolved.
