Summary of the effect of cadmium stress on P. cyrtonema tissues. The red color intensity in P. cyrtonema organs shows the level of cadmium. The red color on different pathways indicates that cadmium stress induces reduction of the expression of proteins related to these pathways. Green color indicates that the activity of the peroxidase (POD) and superoxidase dismutase (SOD) increased in P. cyrtonema rhizomes. Red outlines in different pathways indicate that cadmium stress significantly affected those pathways
