AM roots have two pathways for nutrient absorption, directly through the root epidermis and root hairs and via AMfungal hyphae into root cortical cells, where arbuscules or hyphal coils provide symbiotic interfaces. New physiological and molecular evidence shows that for phosphorus the mycorrhizal pathway (MP) is operational regardless of plant growth responses (positive or negative). Amounts delivered cannot be determined from plant nutrient contents because when responses are negative the contribution of the direct pathway (DP) is reduced. Nitrogen (N) is also delivered to roots via an MP, but the contribution to total N requirement and the costs to the plant are not clear. The functional interplay between activities of the DP and MP has important implications for consideration of AM symbioses in ecological, agronomic, and evolutionary contexts. 28 pp. LOMv1.0 creator LOMv1.0 Project Final Beneficiary LOMv1.0 Project Executing Organisation 2011 LOMv1.0 training LOMv1.0 higher education 18+ Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text plant nutrient uptake pathways, phosphorus uptake, nitrogen uptake, mycorrhizal growth responses 1303223 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/2326/2/2326_Roles%20of%20Mycorrhizas%20in%20plant%20nutrition%20and%20growth.pdf Πανεπιστήμιο Θεσσαλίας.
