High impact information on AMIPROPHOS

• Selective inhibition of tubulin synthesis by amiprophos methyl during flagellar regeneration in Chlamydomonas reinhardi [1].
• This pattern of altered sensitivity to different microtubule inhibitors was found to cosegregate and corevert with the beta-tubulin mutations providing the first genetic evidence that the in vivo herbicidal effects of the dinitroanilines, amiprophos methyl, and pronamide are related to microtubule function [2].
• Further experiments with synchronous cultures prepared by size selection showed that different drugs possessed different transition points; for example, carbendazim and thiabendazole were effective in blocking a late stage of the cell cycle just prior to division, whereas amiprophos methyl affected a very early stage [3].

Biological context of AMIPROPHOS

• The effect of colchicine on bouquet formation appeared to be separable from its effect on cytoplasmic microtubules; amiprophos methyl, a highly effective plant microtubule-depolymerizing drug, did not affect telomere clustering [4].
