The mechanism behind tenuazonic acid-mediated inhibition of plant plasma membrane H⁺-ATPase and plant growth.

ABSTRACT: The increasing prevalence of herbicide-resistant weeds has led to a search for new herbicides that target plant growth processes differing from those targeted by current herbicides. In recent years, some studies have explored the use of natural compounds from microorganisms as potential new herbicides. We previously demonstrated that tenuazonic acid (TeA) from the phytopathogenic fungus Stemphylium loti inhibits the plant plasma membrane (PM) H⁺-ATPase, representing a new target for herbicides. In this study, we further investigated the mechanism by which TeA inhibits PM H⁺-ATPase and the effect of the toxin on plant growth using Arabidopsis thaliana. We also studied the biochemical effects of TeA on the PM H⁺-ATPases from spinach (Spinacia oleracea) and A.
