Functional biology of plant phosphate uptake at root and mycorrhiza interfaces

Summary Phosphorus (P) is an essential plant nutrient and one of the most limiting in natural habitats as well as in agricultural production world‐wide. The control of P acquisition efficiency and its subsequent uptake and translocation in vascular plants is complex. The physiological role of key cellular structures in plant P uptake and underlying molecular mechanisms are discussed in this review, with emphasis on phosphate transport across the cellular membrane at the root and arbuscular–mycorrhizal (AM) interfaces. The tools of molecular genetics have facilitated novel approaches and provided one of the major driving forces in the investigation of the basic transport mechanisms underlying plant P nutrition.…
