Cadmium (Cd) stress is one of the most challenging environmental problems that adversely affects growth and development of plants. Plants adopt various strategies to overcome the adverse effects of Cd stress. Among these, recently phytohormones and osmolytes have been involved in overcoming the adverse effects of Cd stress. Proline is an important osmolyte that maintains cellular homeostasis through osmotic regulation and regulates physiological processes under Cd stress. The role of phytohormones under Cd stress is critical in modulating physiological responses that eventually leads to adaptation of plants to an unfavorable environment. The individual role of both proline and phytohormones has been extensively studied, but a comprehensive study on the interaction of phytohormones with proline under Cd is lacking. The present study focuses on enhancing our understanding on the mechanism of Cd tolerance via proline and phytohormones with emphasis on phytohormones’ interaction with proline under Cd stress.
