Introduction

Arsenic (As) is a toxic contaminant that is ubiquitously distributed in the environment. Though As is a non-essential metalloid for plants, it can be accumulated in plants to toxic levels and hamper plant productivity by impairing various physiological, biochemical, and molecular processes, posing serious threats to sustainable agriculture. Additionally, reducing As accumulation in food crops is of great importance to ensure food safety and public health. 

Role of AMF in amelioration of Arsenic stress

In recent years, significant advancements have been made to elucidate the ameliorative roles of AMF in redeeming As toxicity in crop plants. AMF attenuate As toxicity in plants through its direct roles in As immobilization, transformation, methylation, and volatilization and indirect roles such as facilitating nutrient acquisition, augmenting plant biomass, boosting As sequestration to cell vacuoles, strengthening antioxidant defence, protecting the photosynthetic reaction centre, and restoring metabolic alterations in its host. to augment As tolerance.

Scope of the review

This review describes various routes, which are held accountable for the uptake of As and summarizes the current understanding with respect to AMF-mediated mitigation of As stress and the strategies employed by AMF to cope with stressful environment. The molecular and physiological intricacies of plant-AMF symbiosis in the context of As stress, which would help in exploring new insight into the mechanisms of As remediation by utilizing AMF are also discussed. Finally, the gaps in understanding and future of the research are described to improve theoretical understanding, promote the relevant research progress, and encourage field applications.
