 note = {Bulletin, Potassium (K) is one of the important fertilizer elements in agriculture, and the importance of proper use management of K fertilizer has increased in recent years from the viewpoint of global population increase and food security. The purpose of this study was to clarify how the functional groups present on the root and root cell wall surface of rice plants differ depending on the K environment in the soil. In this study, in addition to rice, we cultivated tomato as a control plant, collected roots, and conducted experiments focusing on the morphology of these roots and the adsorption of ions on the functional groups of the roots. First, we examined the effects of different K supplies (mineral-K plot, available-K plot, and no-K plot) on K uptake and root morphology. Differences in K between treatments were small in both the above-ground and below-ground parts. In addition, elements extracted sequentially from roots cultivated under different K conditions were clearly different between rice and tomato: rice root surface had adsorption sites of iron more abundantly than tomato, and these sites was largely unaffected by the K environment. These results suggest that the ability to adsorb metals on the cell wall surface of rice roots is stronger than that of tomato roots, and that the morphology and functions of rice roots are independent of the K environment. It is possible that the strong reactivity of the root surface of rice to metals may play a role in the ability of crops to withstand reduced fertility through the dissolution of nutrients, such as K, from minerals.},
