Free amino acid regulation in fronds and roots of two pteris cretica L. Ferns under arsenic stress
Original language description
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.
