Mostrar más [+] Menos [-]Humans consume low quantities of cadmium (Cd), a non-nutritive and potentially toxic heavy metal, primarily via the dietary intake of grains. As part of a larger study designed to assist in the breeding of low Cd-accumulating flax varieties, we have conducted an experiment to determine physiological and developmental differences in Cd content in four flax cultivars (AC Emerson, Flanders, CDC Bethune, and AC McDuff). Our objective was to identify varietal differences in the uptake and distribution of Cd in various tissues among flax cultivars grown in naturally Cd-containing soil in a controlled environment. Cadmium concentration was dependent on the flax variety, developmental stage, and tissue type, as well as their interaction and our results suggest varietal differences in the mechanisms that determine Cd content in seeds. The results of this project, combined with those from genomics and field experiments, will support and accelerate the breeding of adapted flax varieties with low levels of Cd in the seed.
