Název v původním jazyce
Free amino acid regulation in fronds and roots of two pteris cretica L. Ferns under arsenic stress
Popis výsledku v původním jazyce
In the present study, free amino acid (AA) regulation in As hyperaccumulating ferns was evaluated in a pot experiment to determine the relationship between As stress and the characteristic change in metabolism of AAs. The ferns Pteris cretica cv. Albo-lineata (Pc-Al) and cv. Parkerii (Pc-Pa) were exposed to As tre¬atments at 0, 20, 100, and 250 mg As/kg for 90 days. Greater As content, as well as higher biomass production, were identified in Pc-Al compared with Pc-Pa. The results indicate a disturbance in N and C metabolisms. Pc-Pa accumulated higher amounts of free AAs than Pc-Al. The total free AA content, as well as the ratio of the main AA family pathway (glutamate family), were increased by the accumulation of toxic As in the ferns. Pc-Al tolerates higher As doses better due to changes in AA biosynthesis, however, at higher As doses, Pc-Pa upregulated AA biosynthesis due to As toxicity. The most abundant free AAs of ferns was glutamine, which was enhanced by As.
