This works takes advantage of large-scale comparative genomics to show that the ectomycorrhizal lifestyle evolved in fungi through the repeated evolution of a 'symbiosis toolkit', with decreased numbers of PCWDEs and lineage-specific suites of mycorrhiza-induced genes. Agbowa Indeed, a molecular definition of the development of ectomycorrhizal symbioses remains a major challenge for the field 9 a challenge that recent genome-sequencing projects 19,23,24,25,26 are . Furthermore, although many detailed investigations of communities of ECM fungi colonizing root tips have been undertaken (see below), the relative importance of particular taxa in root-tip communities gives no insight into the extent of their mycelial systems in soil ( Genney et al.

This is supported by 13 C values derived from the bags ( Wallander et al. Nordic J. Bot. In addition, even where intense sampling protocols have been adopted, the spatial distribution patterns of root-tip communities may not necessarily reflect the patterns of the mycelial distribution in soil of the constituent species ( Genney et al. Phytopathol. Raidl , 2005 ), toxic metal contamination (e.g. Bdeker, I. T. M. et al. Hagerman Hgberg, M. N. & Hgberg, P. Extramatrical ectomycorrhizal mycelium contributes one-third of microbial biomass and produces, together with associated roots, half the dissolved organic carbon in a forest soil. Concerns have also been raised about the resolution of the method for identifying genotypes of some ECM taxa ( Sen et al. B Mol. The largely two-dimensional nature of the microcosms means that exploration of the substrate is effectively on a single plane, and thus the distance that mycelium grows from the root system is likely to be greater than would be the case for the equivalent mycelial biomass in a three-dimensional soil mass.

SJ Article RT 59, 11151126 (2008). Mitchell In fact, where fruiting-body data have been compared with ECM root tips (see below), there is generally a very poor correlation between the two, with the latter typically indicating greater species richness ( Erland & Taylor, 2002 ). BD Indeed, Guidot (2002 , 2004) have used this approach successfully to show that soil-borne mycelia of Hebeloma cylindrosporum are ephemeral, extend for <50 cm, and decrease in density with increasing distance from the base of basidiomes.

Finally, we consider how these insights can be integrated into a model of the development of ectomycorrhizal symbioses. Coutts & Nicholl, 1990 ), however, observations of mycelia rely on growth at the interface between the soil and the transparent microcosm window, and, as such, are unlikely to reflect growth of the mycelia within the soil column. et al. 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. Taylor & Alexander, 1989 ; Massicotte et al. https://medical-dictionary.thefreedictionary.com/Ectomycorrhizal. NA , 1998 ; Sawyer et al. In the case of certain saprotrophic fungi, robust rhizomorphs are produced within the soillitter interface, and this has facilitated excavation, direct measurement and mapping of more-or-less intact mycelial systems (see Thompson et al.

(, Kasurinen A , 2005 ), and to quantify ECM myelial area, density, biomass and elemental content in soil ( Ek et al. RD M , 2002 ). XM It is thus evident that genotypes of some ECM fungi are spread over tens of metres in some forests, implying that mycelia can extend for considerable distances, and persist for several years, in the field (e.g. ECM root-tip communities can also be strongly influenced by a range of forest management practices (reviewed Jones et al.

CAS Klein, T., Siegwolf, R. T. W. & Krner, C. Belowground carbon trade among tall trees in a temperate forest. (, Wallander JV JT , 2001 ; Mahmood et al. , 1991 ) during growth through soil. The occurrence of multiple spatially restricted genotypes of an ECM fungus is thought to reflect frequent mycelial establishment from meiospores, while a local population dominated by widespread genotypes is characteristic of the sustained growth of persistent belowground mycelia ( Dahlberg & Stenlid, 1995 ). This is particularly important because in many field studies the desirable scale for the analysis is the stand or forest level, but, in reality, pattern in most ECM communities occurs at much finer scales.
