Abstract
Complex environmental interactions may modify toxicity of metals. We studied responses of the common medicinal plant chamomile to lead (Pb) toxicity under nitrate sufficient (+ N) or deficient (-N) conditions involving also inhibitor of the key phenolic enzyme phenylalanine ammonia-lyase (2-aminoindane-2-phosphonic acid, AIP). Data indicate that N deficiency depleted nitrogenous but elevated phenolic metabolites or peroxidase activity and enhanced ROS (but not nitric oxide) formation evoked by Pb or AIP. Pb stimulated individual phenolic acids in the shoots but had no impact on total soluble phenols or flavonols where the impacts of AIP and N nutrition were more evident. Pb rather affected glutathione while N deficiency ascorbic and malic acids and the involvement of AIP in these changes was visible. PCA analyses showed clear separation with respect to N deficiency or AIP application. Besides, application of AIP stimulated accumulation of Pb in shoots and in absorbed root fraction while N deficiency suppressed Pb amount in shoots and stimulated in roots. Our data, to our knowledge for the first time, confirm that uptake of metals is not only a simple function of its presence but that mineral nutrition and state of the secondary metabolism have crucial impact on resulting responses.
