 note = {Aims The mechanisms underlying magnesium (Mg)
uptake by plant roots remain to be fully elucidated. In
particular, there is little information about the effects of
Mg deficiency on Mg uptake activity. A Mg uptake
kinetic study is essential for better understanding the
Mg uptake system.
Methods We performed a Mg uptake tracer experiment
in rice plants using 28Mg.
Results Mg uptake was mediated by high- and lowaffinity
transport systems. The Km value of the highaffinity
transport system was approximately 70 μM
under Mg-deficient conditions. The Mg uptake activity},
