Abstract: Cadmium pollution in water or soil was one of the most common heavy metal pollution which threated to plants growth.The physiological mechanism of plant tissues or cells would be inhibited under cadmium stress.At the same time，the plants developed coping strategies in the evolution of the process of cadmium absorption，transport and discharge.Effects of cadmium on plants growth and separation，separation techniques of membrane protein，and plant membrane protein research under conditions of cadmium stress were discussed.
