Title: Lack of prevention of chlorsulfuron‐induced inhibition by amino acids
Abstract: Summary The amino acids valine and isoleucine, which had been indicated by Ray (1984) as antidotes against growth inhibition of pea plants induced by chlorsulfuron, were ineffective in preventing the damage induced by chlorsulfuron on the plasma membrane of maize roots as measured by K + uptake. In addition, in seedlings of two corn genotypes and three pea genotypes grown in culture solution containing chlorsulfuron, growth inhibition was not alleviated by valine and isoleucine. However, in agreement with Ray's results, acetolactate synthase, the key enzyme of the biosynthesis of valine and isoleucine, was inhibited in vitro by chlorsulfuron in both maize and pea. It is suggested that the chlorsulfuron mechanism of action involves several sites.
