Cadmium and Nickel Uptake Are Differentially Modulated by Salicylic Acid in Matricaria chamomilla Plants

Popis výsledku v původním jazyce

Chamomile (Matricaria chamomilla) is a widely used medicinal plant which also accumulates heavy metals in its above-ground organs. We investigated the effect of the important plant signaling molecule, salicylic acid (SA), on the accumulation of Ni or Cd,by exposing plants over 7 days to 60 ?M solutions of individual heavy metals with or without 50 ?M SA. Special emphasis was focused on phenolic metabolism-related parameters, not only because of their importance for growth and stress tolerance but alsobecause phenolics are potent antioxidants in human diet. In combined treatments, SA stimulated an increase in soluble proteins of roots and reduced their water content. SA reduced total Cd in the shoot and increased Ni. Total and ?intraroot? Ni decreasedin Ni + SA treatment, while in the case of Cd, only ?intraroot? content decreased in Cd + SA treatment, being correlated with cell wall-bound phenolic acids and lignin. SA was strongly accumulated in roots from the Ni + SA treatment, bei
