Název v původním jazyce

Cadmium-induced production of phytochelatins and speciation of intracellular cadmium in organs of Linum usitatissimum seedlings

Popis výsledku v původním jazyce

The capacity of most flax (Linum usitatissimum L.) varieties and cultivars to accumulate cadmium (Cd), underlined by their Cd-tolerant phenotype, brought an interest in their use in phytoextraction of soil Cd to aboveground biomass. The aim of this studywas to gain an insight into the mechanism of intracellular detoxification of Cd, by exploring the response of flax seedlings, cultivar AGT 952, to 12 days growth at 50--500 mikroM Cd. The majority of accumulated Cd (67--74%) was retained in roots, whichshowed reduced elongation (by 50% at 100 mikroM Cd) and 3.5 (at 50 mikroM Cd) to 9.6 (at 500 mikroM Cd) times higher concentration of Cd than in shoots. Labeling of roots with Leadmium fluorescent marker visualized intracellular localization of Cd. High-performance liquid chromatography of extracts from Cd-treated seedlings revealed induced synthesis of phytochelatins, small intracellular peptides binding Cd through cysteine of their repeating (gamma-Glu-Cys)n motives (PCn). Regardless
