|The low level of selenium in soils from different Romanian areas indicates a need for its supplementation. Biofortification through treatments applied to crops has the advantage of supplementation of food chain with controlled levels of selenium compounds, with high bioavailability. We present a biotechnological approach of biofortification, adapted to the conditions specific for the soils from SouthEastern part of Romania, which is based on the use of selected plant growth promoting rhizobacteria (PGPR). We evaluated, in controlled experiments, the ability of selected PGPR to increase, in a reference South-East Romania soil, the selenium bioavailability for wheat plant. We integrate this selenium biofortification biotechnology into a GIS-based decision support system. We are discussing Se biofortification in relation with its interferences with polyamines metabolism. We are evaluating the potential use of a new emerging biotechnological approach, based on plant tissue nitric oxide inductors, for a more equilibrated selenium compounds accumulation.
