Abstract:

Cadmium(Cd)is a heavy metal pollutant with heavy toxicity,ranking the first in soil inorganic pollutants. Cd can be absorbed by plants because of its strong fluidity and solubility. It affects the normal physiological metabolism of plants,reduces crop quality,and endangers human health through the transmission and enrichment of the food chain. Therefore,the response mechanism of plants to Cd stress has become a research hotspot. This paper reviews the damage effects of Cd stress on plant physiological metabolism and molecular level,and summarizes the tolerance mechanism that plants have evolved under Cd stress,aiming to provide a theoretical basis for cultivating low-accumulation crops and super-accumulation plants of remediating Cd contaminated soil.

Key words: Cd stress, tolerance, physiological index, molecular mechanism
