Summary • Physiological and molecular responses to phosphorus (P) supply and mycorrhizal infection by Glomus intraradices were compared in European (River) and African (H511) maize (Zea mays) cultivars to examine the extent to which these responses

Semi-natural calcareous and acidic grasslands are known to be sensitive to increased atmospheric N deposition. However, the fate of pollutant N within these systems is unknown. This paper reports on the first studies to determine the fate of added N

Summary • While it is accepted that many ectomycorrhizal fungi can assimilate organic substrates and facilitate transfer of their elemental components to plants, the fate of the carbon contained in these materials remains uncertain. Here we investi

It is well established that ectomycorrhizal fungi can use amino acids as nitrogen and carbon sources, but data on the kinetic properties of amino acid uptake systems of ectomycorrhizal systems are scarce. Using 14C-labelled compounds we have determin

summary The effects of repeated nitrogen fertilization over three years (1989–92) on mycorrhizal infection of Calluna vulgaris (L.) Hull growing in peat soils in north Wales are described. Solutions of NH4NO3 were added at regular intervals (10 to

Fungi with dematiaceous septate hyphae, termed dark septate endophytes (DSE), are common in plant roots, particularly in cold-stressed habitats, but their effects on their host plants remain obscure. Here, we report a study that assessed the effects

The ericoid and an ectomycorrhizal fungus were each grown in liquid medium with protein as the sole source of nitrogen and, with the exception of one set of cultures of the ericoid endophyte, in the presence of exogeneous glucose. Dry weight yields w

Phenolic acids and tannins are known to inhibit protein degradation in soils. This study describes the effects of some of these compounds on the activity of the extracellular proteinase enzyme of an ericoid endophyte, and upon growth and protein util

* Stable isotope abundance analyses recently revealed that some European green orchids and pyroloids (Ericaceae) are partially myco-heterotrophic, exploiting mycorrhizal fungi for organic carbon and nitrogen. Here we investigate related species to as
