ABSTRACT
Vacuolar transport plays a key role in P movement for longer distances along the hyphae of mycorrhizal fungi. Further details on factors that influence vacuole formation, P accumulation and transport are required. Genetic variations, if any, for vacuolar transport of P should be identified. It may have relevance to P transport efficiency of AM/ECM fungal isolates. Are there any fungal isolates that lack ability to form vacuoles and transport P through them? Studies on genetic and molecular control of vacuole formation and vacuolar transport of P need a great deal of attention.
