Abstract

To unravel the working mechanism of the fungicidal piperazine-1-carboxamidine derivative BAR0329, we found that its intracellular accumulation in Saccharomyces cerevisiae is dependent on functional lipid rafts. Moreover, BAR0329 induced caspase-dependent apoptosis in yeast, in which the mitochondrial fission machinery consisting of Fis1 (Whi2), Dnm1 and Mdv1 is involved. Our data are consistent with a prosurvival function of Fis1 (Whi2) and a proapoptotic function of Dnm1 and Mdv1 during BAR0329-induced yeast cell death.
