TL;DR: The results of multiple different but highly related genets in a small area suggest that the population of S. grevillei in this stand is not spread and maintained by clonal mycelium extension but is reproduced by spore dispersal.
Abstract: Clones of ectomycorrhizal fungi can colonize new areas through production of vegetative mycelium or spore dispersal, but the relative importance of these processes in nature is not known. In this study, sporocarps of an ectomycorrhizal fungus, Suillus grevillei, were mapped and sampled from a Larix kaempferi stand at the foot of Mt Fuji. DNA was extracted directly from each sporocarp, and DNA polymorphism was analysed by polymerase chain reaction (PCR) amplification of inter-simple sequence repeat (ISSR) regions primed by (GTG)5, (GCC)5 and (GACA)4. Different sensitivities to detect polymorphism were found among the three primers, with (GACA)4 showing the highest sensitivity. Forty seven sporocarps were analysed by the three ISSR primers and divided into 34 genets based on combination of PCR fingerprints. In the population 28 genets were represented by individual sporocarps. In most cases, sporocarps grown in aggregation (within a circle of 50 cm diameter) showed some different ISSR band patterns. These results suggest that genets of S. grevillei at the test site are relatively small. The genetic similarities between the 34 genets were also calculated and similarity groups were determined by the criterion that all similarity F values of genets within a group were not <80%. In general, the genets within a similarity group located close to each other. The results of multiple different but highly related genets in a small area suggest that the population of S. grevillei in this stand is not spread and maintained by clonal mycelium extension but is reproduced by spore dispersal.

TL;DR: Any in vitro studies undertaken on compatibility and specificity in ectomycorrhizal associations should omit carbohydrate from the medium or use an aseptically synthesized donor host as the source of fungal inoculum.
Abstract: The effect of the presence of an exogenous carbon source in the synthesis medium on compatible and incompatible interactions between Suillus grevillei (Klotzsch) Sing. and a number of ectomycorrhizal hosts has been studied at the ultrastructural level. Comparisons are made with the results of the previous study in which carbohydrate was omitted. Observations suggest that the availability of an external source of carbon to the fungus upsets the balance of the symbiosis in favour of the fungal partner, even in compatible interactions, causing changes in the host cell wall and at the host-fungus interface. The rate and degree of colonization of the root surface is also influenced by the presence of carbohydrate in the synthesis medium. These results suggest that any in vitro studies undertaken on compatibility and specificity in ectomycorrhizal associations should omit carbohydrate from the medium or use an aseptically synthesized donor host as the source of fungal inoculum.

TL;DR: Evidence is examined for tree species- mycorrhizal specificity, and the mechanisms involved (e.g., signal compounds) and what is known about the effects of these associations and interactions with other soil organisms on the quality and quantity of C flow into the myCorrhizosphere (the area under the influence of mycor rhizal root tips), including spatial and seasonal variations are explored.
Abstract: Mycorrhizal associations are ubiquitous and form a substantial component of the microbial biomass in forest ecosystems. Some 10,000 species of ectomycorrhizal fungi are currently recognized, some of which are host specific and will only associate with a single tree species, for example, Suillus grevillei with larch. Mycorrhizae are a strong sink for plant C; differences in mycorrhizal anatomy, particularly the presence and extent of emanating hyphae, can affect the amount of plant C allocated to these assemblages and results in qualitative and spatial variations in soil nutrient availability and acquisition. Mycorrhizal morphology affects not only spatial distribution of C in forests, but also differences in the longevity of these diverse structures have important consequences for C sequestration in soil. Through new genomic techniques we are beginning to understand the mechanisms involved in the specificity and selection of ectomycorrhizal associations, though much less is known about arbuscular mycorrhizal associations. In this review we examine evidence for tree species- mycorrhizal specificity, the mechanisms involved (e.g. signal compounds). We also explore what is known about the effects of these associations and interactions with other soil organisms on the quality and quantity of C flow into the mycorrhizosphere (the area under the influence of mycorrhizal root tips), including spatial and seasonal variations. The enormity of the mycorrhizosphere biome in forests and its potential to sequester substantial C belowground points to the vital knowledge gap on the dynamics of the different mycorrhizal functional groups in diverse forests.
