Phosphorus application modulates cadmium toxicity in rice (Oryza sativa L.) by affecting the antioxidant defense system and regulating the expression of iron uptake/transport-related genes
Exogenous phosphorus (P) application can affect the degree of cadmium (Cd) accumulation in plants. In this study, a high-Cd accumulating rice cultivar (Fupin 36) was used to investigate the relationship between P and Cd. Pot experiments (hydroponics and soil culture) showed that Cd exposure inhibited increases in plant biomass and interfered with the uptake of nutrient elements. However, application of appropriate levels of P mitigated the deleterious effects of Cd and decreased Cd accumulation in rice, whereas application of a high level of P exacerbated Cd toxicity, indicating that Cd accumulation was P concentration/availability-dependent. Kinetics analysis showed that Cd uptake in the roots was positively correlated with the P absorption pathway. Appropriate levels of exogenous P application increased the activity of antioxidant enzymes (including superoxide dismutase, peroxidase, catalase, and ascorbate peroxidase) and alleviated the effect of lipid peroxidation on plant growth, which ameliorated Cd-associated toxicity. The content of various elements significantly changed in response to P application and Cd stress; Fe accumulation reduced, and the expression of Fe-responsive genes (e.g., OsNRAMP1, OsIRT1, OsYSL15, OsIRO2, and OsNAS2) was altered. These findings indicated that P regulated Cd (im)mobilization by mediating the Fe homeostasis pathway in plants. In conclusion, P contributes to Cd toxicity in rice by modulating antioxidant defense and thus Cd tolerance and by interfering with the Fe uptake-associated pathway (strategy I and II systems). Additionally, appropriate levels of P application can enhance the Cd detoxification process and plant growth and ensure grain production and security.
