Conclusion and Future Perspectives
Arsenic contamination in food chain is challenging issue for researchers. Various
aspects of the study include biochemical, molecular, physiological and anatomi-
cal changes appeared in the plants as a result of arsenic exposure. Moreover, there
are new findings regarding methylation of inorganic arsenic, uptake mechanism
and accumulation of arsenic in plant. The role of transporters in uptake and vacu-
olar localization reveal that these processes are the key to understand As-resistance.
There is considerable knowledge gap regarding arsenic mediated hindrance in plant
physiological reactions, nutrient uptake, pathway of oxidative stress and effect on
crop yield. This basic information will be significant in phytoremediation studies
to eradicate the arsenic contamination from agricultural soil. We can acquire new
insight about arsenic and plant interaction by using molecular advances and sophis-
ticated analytical technologies. So, research should focus on combing physiology
and genetics to breed plants with low arsenic in edible plant parts and productivity.
