摘要: We employed field and laboratory assays to determine the capacity of wild tobacco (Nicotiana attenuata) to detect and direct root growth towards localized nutrient patches. Our findings demonstrate that directed root growth underlies foraging behavior, and that chemotropism and micronutrient-guided root placement are important factors shaping root architecture in nature.
