- Abstract
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 South- Eastern 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.
