2-Benzoxazolinone (BOA) is a phytotoxic compound that induces strong effects on plant metabolism. BOA effects include increased membrane permeability, degradation of proteins and pigments, increased lipid peroxidation, oxidative stress and senescence induction. In this work, the effects of amino acid supplementation on BOA action were analyzed. Roles of histidine, tryptophan and cysteine in the mode of action of BOA action are proposed from their protective effects.
Keywords: Phytotoxic compound, benzoxazinone, mode of action, amino acid metabolism.
