Abstracts |
This Update reviews new findings about the roles of arbuscular mycorrhizas (AM) in plant growth and phosphorus (P) nutrition. Focus is given particularly on the function of AM symbioses with different outcomes for plant growth (from positive to negative) and especially on the interplay between direct P uptake via root epidermis (including root hairs when present) and uptake via the AM fungal pathway. The results are highly relevant to many aspects of AM symbiosis, ranging from signalling involved in the development of colonization and the regulation of P acquisition to the roles of AM fungi in determining the composition of natural plant assemblages in ecological settings and their changes with time. |
