Sokolovski, S.G., Meharg, A.A. and Maathuis, F.J.M. (2002) Calluna vulgaris root cells show increased capacity for amino acid uptake when colonized with the mycorrhizal fungus Hymenoscyphus ericae. New Phytologist, 155 (3). pp. 525-530. ISSN 0028-646X
Abstract
• Ericoid mycorrhizas are believed to improve N nutrition of many ericaceous plant species that typically occur in habitats with impoverished nutrient status, by releasing amino acids from organic N forms. Despite the ubiquity of mycorrhizal formation the mechanisms and regulation of nutrient transport in mycorrhizal associations are poorly understood.
• We used an electrophysiological approach to study how amino acid transport characteristics of Calluna vulgaris were affected by colonization with the ericoid mycorrhiza fungus Hymenoscyphus ericae .
• Both the V max and K m parameters of amino acid uptake were affected by fungal colonization in a manner consistent with an increased availability of amino acid to the plant.
• The ecophysiological significance of altered amino acid transport in colonized root cells of C. vulgaris is discussed.
