Morpho-physiological and Proteome Analysis of Citric acid Induced Phytoremediation under Copper Stress in Brassica napus L.

Phytoremediation, one of popular way, has low cost and environment friendly nature as compared with chemical ways. Various hyperaccumulator plants can perform phytoremediation, especially Brassica. Among Brassicas canola has advantages such as big canopy, short period of growth and heavy metal tolerance. Citric acid (CA) is one of organic chelating which can enhance phytoremediation and has more biodegradability and environment friendly nature against chemical chelating. Copper (Cu) is essential nutrient but excess Cu may cause chlorosis and root is restrained. In this study, we investigate the potential role of CA increasing phytoremediation of Cu and effect of CA induced phytoremediation of brassica napus L. on physiological, biochemical and protein changes under Cu stress
