“…Although these interactions may be of great importance for C and nutrient cycling in soil, they are poorly studied, especially beyond relatively simple laboratory systems (Fitter and Garbaye 1994;Klironomos et al 1997;Hodge 2000; Barea et al 2002). In laboratory experiments both neutral and negative interactions between AM and ST fungal species have been found (McAllister et al 1994(McAllister et al , 1996Larsen et al 1998;Filion et al 1999;Green et al 1999). It has also been shown that AM fungi affect the community structure of ST fungi and bacteria (Linderman 1988;Andrade et al 1998;Vazquez et al 2000;Marschner et al 2001;Marschner and Baumann 2003).…”

Arbuscular mycorrhiza and Collembola interact in affecting community composition of saprotrophic microfungi

The functioning of the plant-mycorrhiza system depends on interactions with other organisms, including saprotrophic (ST) soil fungi. The interactions between mycorrhizal and ST fungi are likely affected by fungivorous soil animals, such as Collembola. In a two-factorial laboratory experiment lasting for 30 weeks we assessed the effects of an arbuscular mycorrhizal fungus (Glomus mosseae) and Collembola (Protaphorura fimata, Heteromurus nitidus and Folsomia candida) on the community composition of ST microfungi in soil planted with the invasive grass Cynodon dactylon. The presence of mycorrhiza substantially reduced total plant biomass and reduced N and P availability to the soil microflora, though these effects were less pronounced in the presence of Collembola. The density of Collembola was high (corresponding to about 2x10(5) individuals m-2) and was not affected by the presence of G. mosseae. In spite of the large amount of mycorrhizal mycelium in soil, it contributed little to Collembola nutrition. The presence of mycorrhiza strongly affected the community structure of ST soil fungi. In particular, mycorrhiza reduced the relative abundance of Trichoderma harzianum and Exophiala sp., but increased the abundance of Ramichloridium schulzeri and several sterile forms. However, the difference between fungal communities in mycorrhizal and non-mycorrhizal treatments was much more pronounced in the presence of Collembola. Presumably, the intense grazing by Collembola destabilized the ST fungal community, thereby making it more susceptible to the influence of G. mosseae. These results document for the first time that fungal feeding soil invertebrates can significantly affect the interactions between mycorrhizal fungi and ST soil microorganisms.

“…On the other hand, T. harzianum populations were generally reduced in the presence of AMF, except in the case of the co-inoculation with Glomus intraradices. This could be due to the modifications of root exudates or to substances released by the extramatrical mycelium (McAllister et al 1994;Filion et al 1999;Martínez et al 2004). Competition between T. harzianum and AMF in the first establishment stages, which could be maintained in time, has been also proposed to explain these findings (McAllister et al 1994;Green et al 1999).…”

“…This could be due to the modifications of root exudates or to substances released by the extramatrical mycelium (McAllister et al 1994;Filion et al 1999;Martínez et al 2004). Competition between T. harzianum and AMF in the first establishment stages, which could be maintained in time, has been also proposed to explain these findings (McAllister et al 1994;Green et al 1999). Competition for host photosynthates or sites, microbial changes in the rhizosphere due to the presence of AMF species, and induction of local and systemic defence responses have been proposed (Caron 1989; Azc on-Aguilar and Bago 1994).…”

“…For example, it has been reported that some Trichoderma strains may influence AMF activity (Calvet et al 1992(Calvet et al , 1993Brimner and Boland 2003;Martinez et al 2004;Martínez-Medina et al 2009). Volatile and soluble exudates produced by saprophytic fungi are involved in these effects (McAllister et al 1994(McAllister et al , 1995Fracchia et al 1998). Nevertheless, the results of research on the interactions between soil saprophytic and AMF differ widely, even when the same species of saprophytic fungi are involved.…”

“…McAllister et al (69) tested the effect of Trichoderma koningii and Fusarium so/ani on growth and mycorrhiza formation with maize. They found that T koningii, when applied together with G. mosseae, decreased mycorrhizal fungus colonization infection of the root whereas F. so/ani caused no significant effects in an experiment with maize.…”

Abstract:futeractions between arbuscular mycorrhizal (AM) fungi and other soil microorganisms (including bacteria, saprophytic microfungi, actinomycetes and some microarthropods) are described as well as the phenomena of the rhizosphere, mycorrhizosphere and mycosphere. Examples are given of how the growth of AM fungi and the formation of mycorrhizas are affected by the other soil organisms. All of these co-occuring positive and negative influences upon the interaction between AM fungi and plant roots are shown to underscore the complexity of the soil environment and difficulty in reaching general conclusions.
