Název v původním jazyce

Arsenic accumulation and speciation in two cultivars of Pteris cretica L. and characterization of arsenate reductase PcACR2 and arsenite transporter PcACR3 genes in the hyperaccumulating cv. Albo-lineata

Popis výsledku v původním jazyce

Pollution and poisoning with carcinogenic arsenic is of major concern globally. Interestingly, there are ferns that can naturally tolerate remarkably high As concentrations in soils while hyperaccumulating this metalloid in their fronds. Besides Pteris vittata in which As related traits and molecular determinants have been studied in detail, the As hyperaccumulation status has been attributed also to Pteris cretica. We thus inspected two P. cretica cultivars, Parkerii and Albo lineata, for As hyperaccumulation traits. The cultivars were grown in soils supplemented with 20, 100, and 250 mg kg of inorganic arsenate iAsV. Unlike Parkerii, Albo lineata was confirmed to be As tolerant and hyperaccumulating, with up to 1,3 and 6,4 g As kg dry weight in roots and fronds, respectively, from soils amended with 250 mg iAsV kg. As speciation analyses rejected that organoarsenical species and binding with phytochelatins and other proteinaceous ligands would play any significant role in the biology of As in eithe
