Comparative study of eye defective worm 'menashi' and regenerating wild-type in planarian, Dugesia ryukyuensis.

Abstract excerpt

Inbreeding of the sexualized planarian, Dugesia ryukyuensis, produces eye-defective worms, menashi, in the F1 population. To study the effects of this mutation on the eye, we observed the eye-region of menashi using electron microscopy and compared it with the regenerating eye in wild-type worms. The intact eye of wild-type planarians consisted of a few pigment cells and a number of visual cells. Pigment cells...
