Because a new gene has been inserted into, the soybean our.Hypothesis is that cellmetabolismmay be further altered through.A, cascade reaction which may eventually lead to stressful.Conditions. Our previous research focusing on soybean seeds.Indicated the presence of alterations to enzymes protein species,,[], and 7 the accessibility of metals (primarily iron and copper).[]. Thus 8 - 13, this, in work our main objective was to determine.Whether these modifications are propagated after seeds are.Planted as well, as to further corroborate a previous hypothesis.That the genetic modification itself is a stressful event to the.Plants [12]. To, accomplish this we carried out comparative.Studies taking into, account alterations in the protein species.Profile and in the activities of enzymes involved in combating.Reactive oxygen species (ROS) and an unbalanced redox state. To.Evaluate the oxidative stress of, the plants enzymes / products.Involved in combating ROS were investigated. Enzyme activities.Were determined by spectrophotometric assays 2-D DIGE,,
