Application and mode of action of ferrous sulphate in minimizing Cd in rice was monitored in the present study.<\/jats:p><\/jats:list-item>\n\n<jats:list-item><jats:p>Pot culture with Indian rice variety Swarna (MTU 7029) was maintained in Cd\u2010spiked soil containing ferrous sulphates, which is expected to reduce Cd accumulation in rice. Responses in rhizosphere pH, root surface, metal accumulation in plant and molecular physiological processes were monitored.<\/jats:p><\/jats:list-item>\n\n<jats:list-item><jats:p>Iron plaque was induced on root surfaces after FeSO4 application and the amount of Fe in plaque reduced with increases in Cd in the soil. Rhizosphere pH decreased during plaque formation and became more acidic due to secretion of organic acids from the roots under Cd treatment. Moreover, iron chelate reductase activity increased with Cd treatment, but in the absence of Cd, activity of this enzyme increased in plaque\u2010induced plants. Cd treatment caused expression of <jats:italic>OsYSL18<\/jats:italic>, whereas <jats:italic>OsYSL15<\/jats:italic> was expressed only in roots without iron plaque. Fe content of plants increased during plaque formation, which protected plants from Cd\u2010induced Fe deficiency and metal toxicity. This was corroborated with increased biomass, chlorophyll content and quantum efficiency of photo\u2010synthesis among plaque\u2010induced plants.<\/jats:p><\/jats:list-item>\n\n<jats:list-item><jats:p>We conclude that ferrous sulphate\u2010induced iron plaque prevents Cd accumulation and Fe deficiency in rice.
