| 内容記述 | 1. Plants take nutrients from rhizosphere via two pathways: (1) by absorbing soil nutrients directly via their roots, and (2) indirectly via symbiotic associations with nutrient-providing microbes. Herbivorous insects can alter these pathways by herbivory, adding their excrement to the soil, and affecting plant-microbe associations. 2. Little is known, however, about the effects of herbivorous insects on plant nutrient uptake. We caITied out greenhouse experiments with soybean, aphids, and rhizobia to examine the effects of aphids on plant nutrient uptake. 3. First, we compared the inorganic soil nitrogen and the sugar in aphid honeydew between aphid-infected and -free plants. We found that aphid honeydew added 41 g m-2 of sugar to the soil, and that aphids decreased the inorganic soil nitrogen by 86%. This decrease may have been caused by microbial immobilization of soil nitrogen followed by increased microbial abundance due to aphid honeydew. 4. Second, we compared nitrogen forms in xylem sap between aphid-infected and -free plants to examine nitrogen uptake. Aphids decreased the nitrogen uptake via both pathways, and strength of the impact on direct uptake via plant roots was greater than indirect uptake via rhizobia. The reduced nitrogen uptake by the direct pathway was due to microbial immobilization, and that by the indirect pathway was likely due to the interaction of microbial immobilization and carbon stress, which was caused by aphid infection. 5. Our results demonstrate that herbivorous insects can negatively influence the two pathways of plant nutrient uptake and alter their relative importance.
