Efeito de herbicidas sobre a polimerizacao dos microtubulos e inducao de micronucleos em protoplastos de Helianthus maximiliani

, : Efeito de herbicidas sobre a polimerizacao dos microtubulos e inducao de micronucleos em protoplastos de Helianthus maximiliani. Revista Brasileira de Fisiologia Vegetal 12(3): 263-272

In order to verify the kinetics of microtubule depolymerization and dynamics of micronuclei induction, two anti-mitotic herbicides, Amiprophos-methyl (APM) and Oryzalin (ORY), were added to dividing cells of Helianthus maximiliani. The addition of both herbicides to actively dividing cells resulted in a high number of cells with micronuclei through modification of mitosis. Single chromosomes and groups of 2 or more chromosomes were scattered over the cytoplasm.
