Reduction of Cadmium Uptake in Crop Plants: a Case Study from Soybean

Popis výsledku v původním jazyce

Cadmium is a toxic heavy metal in agricultural soils which is readily taken up by crop plants thus posing a food and feed safety risk. Genetic variation in seed cadmium accumulation has been described in soybean which enables plant breeding to select genotypes for low cadmium content using genetic markers. Therefore, marker analysis as well as pot and field experiments have been carried out to validate a simple sequence repeat (SSR) marker in early maturity genotypes suitable for soybean production in Central Europe. All soybean genotypes were classified into either high or low cadmium accumulating genotypes. Marker results were clearly verified in a pot experiment with different cadmium levels of soil and in soybean harvest samples from three field locations in Austria with a seed cadmium concentration varying between 0.03 and 0.16 mg kg-1. In general, seed cadmium content was reduced by about 50% in low accumulating genotypes as compared to high accumulating ones. Significant variation has also been found for zinc and manganese content of soybean seed, and zinc was positively correlated with cadmium content. Moreover, genetic variation in cadmium accumulation within both the high and low cadmium uptake groups suggests the action of additional genetic mechanisms which could be utilized by selecting lines from appropriate crosses towards a further reduction in cadmium uptake or translocation to seeds.
