Abstract: Soyabean [Glycine max (L.) Merr.] is considered essential due to its high oil production and nutritive value. However, because of the different abiotic and biotic stress, the plant experiences from accumulation of reactive oxygen species (ROS) that results in severe oxidative damage. The effect of abiotic stress such as heavy metals, salinity, temperature and drought were detected on soyabean during crop production. Abiotic stress produces several morphological changes in root, stem and leaf of the plants. Plants possess homeostatic cellular mechanism to regulate the level and concentration of various abiotic factors by using several enzymatic and non enzymatic responses. The cell wall and plasma membrane are the main barriers against the metal pollutants and some other compound present in plants like phytochelatin based sequestration etc. Exposure of heavy metal to the plants could lead multiple toxic effects by inducing reactive oxygen species (ROS), which inhibit most cellular processes at various levels of metabolism. The present study summarizes the response of Glycine max to different biotic, abiotic factors as well as heavy metal pollutants.
