Cadmium(Cd)pollution has emerged as a critical global environmental concern,due to its significant toxicity,environmental persistence,and the pervasiveness of contamination.Significantly,the bioaccumulation of Cd in agricultural crops constitutes a primary vector for its entry into the human diet.This issue warrants urgent attention from both the scientific community and policymakers to develop and implement effective mitigation strategies.This review delves into the physiological impacts of Cd stress on plants,including the suppression of photosynthetic activity,amplification of oxidative stress,and disruptions in mineral nutrient homeostasis.Additionally,the resistance mechanisms deployed by plants in response to Cd stress have been explored,and the prospective contributions of molecular breeding strategies in augmenting crop tolerance to Cd and minimizing its bioaccumulation have been assessed.By integrating and analyzing these findings,we seek to inform future research trajectories and proffer strategic approaches to enhance agricultural sustainability,safeguard human health,and protect environmental integrity.
