Adumbratio motuum rotationis vegetalium.

Rotatio vegetalis est motus morphogeneticus qui internalizationem mesodermis per gastrulationem in embryonibus amphibiorum cogit.[1] Internalizatio cellularum vegetalium ante gastrulationem primum annis 1930 observata est ab Abrahamo Mandel Schechtman per experimenta pittaciorum tincturis affictorum in embryonibus Trituri torosi, speciei urodelorum familiae salamandridarum.[2] Winklbauer et Schürfeld (1999) motus internos per singula addita in explantationibus praegastularibus Xenopus laevis recentius descripserunt.[1]
