Do arbuscular mycorrhizal fungi affect arsenic accumulation and speciation in rice with different radial oxygen loss?

► Rice with higher ROL colonized by AMF led to higher root colonization rates. ► AMF enhanced the root ratios of As(III)/As(V) conc. in rice with high ROL. ► Rice with higher ROL colonized by AMF elevated root ratios of As(III)/As(V) conc. ► The AMF/rice combination significantly affected root total As concentrations.
