Effect of aluminium uptake on physiology, phenols and amino acids in Matricaria chamomilla plants
Original language description
Chamomile is a widely used medicinal plant and, as observed in our previous studies, also accumulates some metals in its above ground biomass. We therefore tested selected metabolic responses after treatments with 60 and 120 uM Al for 7 days. Shoot Al content was not elevated in comparison with control (12.3 14.1 ug g 1 DW) while total root Al increased strongly, reaching 2680 and 4400 ug g 1 DW in 60 and 120 uM treatments, respectively. Intra root Al represented 83.6 (60 M treatment) and 75.8% (120 uMtreatment) of total root Al. Soluble proteins were not significantly affected. Free amino acids were almost unaffected in shoots while in roots the highest content was found in 60 uM Al. Ascorbate and guaiacol peroxidase activities were the highest in 60uM Al exposed roots. On the other hand, phenylalanine ammonia lyase activity, total soluble phenols, flavonoids, a sum of 13 phenolic acids and partially two flavonols (quercetin and kaempferol) increased in the shoots.
