Heavy metal (HM) toxicity is one of the major abiotic stresses leading to hazardous effects in plants. A common consequence of HM toxicity is the excessive accumulation of reactive oxygen species (ROS) that cause lipids peroxidation, oxidation of protein, inactivation of enzymes, DNA damage and/or interactions with other vital constituents of plant cells. The purpose of this study was to determine whether the application of IO can improve the levels of antioxidants to severe cadmium stress in

SDS PAGE 3 analysis of total protein was carried out to evaluate the seed proteins response of the Glycine max L. to 100mM CdCl and 100mM CdCl with IO in dosages of 20, 40, 80µM. SDS PAGE analysis of protein reveals that the 2 2 3 protein expression decreased on the application of 100mM CdCl but supplementing with iodine in low 2 concentrations (20 µM) enhanced the expression of seed proteins of Glycine max L. Our study recommends that IO could be considered a possible beneficial element to counteract the harmful effects of cadmium chloride 3 stress.
