Programmed cell death in pathogenesis induced by herbicides inhibitors of acetyl-CoA-carboxylase

Abstract

Importance of pathogenesis induced by herbicides whose phytotoxic action is caused by the interaction with photosynthesis is discussed. For this class of herbicides, the participation of programmed cell death and the role of reactive oxygen species (ROS) in the induced pathogenesis are shown. However, study of pathogenesis induced by another class of herbicides, inhibitors of acetyl-CoA carboxylase is most important. Previous studies have shown that the phytotoxic action of inhibitors of acetyl-CoA carboxylase are mediated by ROS generation. This investigation showed that herbicide haloxyfop-R-metyl induced fragmentation of DNA isolated from root merystem of maize seedlings (Zea mays L.) in mono-oligonucleosomic cites that is an important marker of the programmed cell death. These data suggest that the programmed cell death is participating in pathogenesis induced by herbicides inhibitors of acetyl-CoA-carboxylase.
