JWG (d) A dense mycelial mat that has been lifted from a rock surface in a native Scots pine forest. Although they did not target ECM fungi specifically, several studies identified mycelia of ECM fungi as being present in the general fungal assemblages of forest soils ( Chen & Cairney, 2002 ; Anderson et al.

MM For example, analysis of ECM root-tip community data from eight studies suggested that it is necessary to take cores at least 3 m apart in order to achieve the greatest sampling efficiency for stand-level community analysis ( Lilleskov et al.

J A division or phylum in the kingdom Fungi that, together with the basidiomycetes, form the subkingdom Dikarya. C ECM mycelial biomass has also been shown to vary with soil depth and host tree species, being generally greater in the upper part of the soil profile than in the underlying soil and correlated with the distribution of tree roots in the profile ( Wallander et al.

Futai P Are you a foodie? J Arnebrant This work has confirmed the observations based on fruiting-body distribution (see above) that genotypes of some taxa are spatially restricted belowground and that the distribution of others can be widespread ( Guidot, 2001; Hirose, 2004; Kretzer, 2004; Lian, 2006 ). R I KK Trends Genet. Moreover, Genney (2006) coupled T-RFLP analysis with a soil-slicing approach to investigate the distribution of ECM mycelia in a volume of soil (800 cm 3 ) at a fine scale. IC With the realization that analysis of ECM fungal communities on the basis of fruiting-body data is a poor indicator of belowground communities of the fungi ( Horton & Bruns, 2001 ; Erland & Taylor, 2002 ) came acceptance that communities of ECM fungi are best analysed on the basis of identification and enumeration of short lateral roots infected by ECM fungal taxa (=ECM roots). Appl. Hitchcock , 1998 ; Sawyer et al. This method centres on analysis of the mycelial genotype in the vegetative tissue of the fruiting body and mapping the distribution of the genotypes in a forest stand. These are nylon mesh (50 m) bags containing acid-washed sand that are buried in soil and later retrieved for analysis of total fungal content by ergosterol or PLFA analysis ( Wallander et al. Curr. & Lindahl, B. D. Class II peroxidase-encoding genes are present in a phylogenetically wide range of ectomycorrhizal fungi. CA Much of the currently available information on the diversity, distribution and dynamics of ECM fungi is derived from investigations of fruiting bodies and ECM root tips, and provides only limited insights into soil-borne ECM mycelial communities. CJ A (, Ek PubMed JA An important observation here has been the foraging behaviour of ECM mycelia in soil and, in particular, their abilities to densely colonize discrete patches of various organic substrates or necromass from which they can effect nutrient mobilization ( Finlay & Read, 1986a , b; Carleton & Read, 1991 ; Bending & Read, 1995a , b; Prez-Moreno & Read, 2000 , 2001a , b; Leake, 2001 ; Lilleskov & Bruns, 2003 ; Donnelly et al. These approaches have the potential to provide unprecedented insights into the functioning of ECM mycelia at the ecosystem level, particularly in the context of land-use changes and global climate change. The importance of analysing ECM fungal communities by direct DNA extraction from soil is emphasized by the lack of congruence between community structures inferred from root-tip and soil-based analyses ( Koide et al. (, Landeweert The soil that surrounds and is influenced by the roots of a plant. Shaver PubMedGoogle Scholar. , 2006 ) or Tricholoma ( Murata et al. (, Carfrae Further studies on how mycelial systems of ECM fungi respond to elevated atmospheric CO 2 concentrations will be crucial to modelling and understanding carbon dynamics in complex forest ecosystems under future climate-change scenarios. With the increasing development of SSR markers for ECM fungi (e.g. Gransson Marmeisse , 2001 ; Sawyer et al. , 2002 ), responses of mycelia to elevated atmospheric CO 2 concentrations (e.g. Dell AFS Gimenez-Ibanez, S. et al. Biol. , 2006 ) there are varying reports of widespread and spatially restricted genotypes. However, the use of basidiomycete-specific primers for the analysis of ECM mycelial communities has been cautioned ( Anderson et al. F New Phytol. Kaipainen Benefits Endomycorrhizal fungi benefit not only a large number of desert plants, but a majority of the plants in the world (Table 1). Genet. Maraun H Upgrading root physiology for stress tolerance by ectomycorrhizas: insights from metabolite and transcriptional profiling into reprogramming for stress anticipation. Ectomycorrhizal fungi are dispersed either by airborne spores or through the transfer of infected plant tissue. R , 2005a ) of ascomycetes in ECM root-tip communities is often high. P TD Elevated atmospheric CO 2 has also been shown to alter ECM fungal root-tip community structure in growth-chamber experiments ( Godbold & Berntson, 1997 ; Godbold et al. , 2005 ; Robertson et al. Taylor Our appreciation of the roles of ECM fungi in these processes is hampered by a fundamental lack of understanding of their mycelial systems in soil. A De la Bastide, 1994 ; Selosse et al.
