Com o objetivo de estudar a cinética da despolimerização dos microtúbulos e a dinâmica da indução de micronúcleos, usaram-se dois herbicidas com ação antimitótica, amiprofós-metil (APM) e oryzalin (ORY), em células de Helianthus maximiliani. A aplicação de ambos os herbicidas em células com ativo crescimento resultou num elevado número de células com micronúcleos, em virtude das modificações mitóticas causadas pela ausência de microtúbulos. Primeiramente, cromossomos isolados ou grupos de 2 ou mais cromossomos espalharam-se pelo citoplasma. Duas a três horas após a aplicação dos herbicidas, os microtúbulos, estavam despolimerizados e os cromossomos metafásicos condensaram-se, formando diretamente os micronúcleos sem ter havido a divisão do ...
