Abstract
Arbuscular mycorrhizal (AM) fungi are vital components of nearly all terrestrial ecosystems, forming mutually beneficial (mutualistic) symbioses with the roots of around 80% of vascular plants and often increasing phosphate (P) uptake and growth.We present novel data showing that AM fungi can provide the dominant route for plant P supply, even when overall growth or P uptake remains unaffected.The results will change our understanding of the roles of AM fungi in agricultural and natural ecosystems; they also predict that mycorrhiza-specific plant P transporters must play a major role in plant P uptake regardless of whether the plants respond to AM colonization by taking up more P per plant or by increased dry weight, compared with nonmycorrhizal (NM) control plants.AM associations are the outcome of 450 million years of co-evolution, which has led to adaptations in both plants and fungi that underpin their symbiotic development and function.The main physiological basis for mutualism is bidirectional nutrient transfer (Smith and Smith, 1990).Plants supply the AM fungi with sugars, and the fungi enhance the ability of the plants to scavenge for scarce and immobile nutrients, particularly P. Different AM fungus-plant combinations are functionally diverse both in effectiveness of the fungi as symbionts and in responsiveness of the plants in terms of total P uptake, growth, and/or reproduction, again compared with NM controls.This diversity has significant influences on plant in-
