Plant Resistance to Heavy Metals Stress

The studies on the effect of heavy metals on plants have shovn that theycause intensification of two types of unfavorable processes:- inactivation of macromolecules and cellular structures,- induction of oxidative stress.All molecular, structural and metabolic changes on the level if molecules,tissues and organs lead to changes of plant morphology. One of tie change isinhibition of plant growth, reflected as a reduction of its size, massof either thewhole plant or its part, organs or tissues.In response the plant activates processes restoring its homeistasis. In removing reversible changes a particular role is played by the proceses of heavymetal detoxification as well as removal of active forms of oxygei.
