In Argentina, 90% of the soybean plants are resistant to glyphosate, varieties RR (Roundup Ready) (Transgenic soybeans). Finding advantageous properties of non-transgenic (NT) over transgenic (T) plants, against different stressors is an interesting challenge in the way of attempting replacement genetically transformed plants with native ones Cadmium (Cd) is a contaminant that interferes with the entry, transport and use of essential elements (Ca, Mg, P and K) and water, causing nutritional imbalances and dehydration, which causes changes in oxidative stress parameters. The aim of this study is to determine the difference in the biochemical mechanisms against oxidative stress by Cd. Leaves of transgenic and non-transgenic soybean with Cd contamination for 24 hours, were used. MDA, H2O2 and catalase were determined. The results for NT (Cd) vs T (Cd) were: H2O2showed a significant increase (p
