Ectomycorrhizal communities in a Tuber aestivum Vittad. orchard in Poland

Cultivation of the Burgundy truffle, Tuber aestivum Vittad., has become a new agricultural alternative in Poland. For rural economies, the concept of landscaping is often considerably more beneficial than conventional agriculture and promotes reforestation, as well as land-use stability. Considering examples from France, Italy, Hungary and Spain, truffle cultivation stimulates economic and social development of small, rural communities. Because there is no long tradition of truffle orchards in Poland, knowledge regarding the environmental factors regulating the formation of fruiting bodies of T. aestivum is limited. Thus, knowledge concerning ectomycorrhizal communities of T. aestivum host species is crucial to ensuring successful Burgundy truffle production. We investigated the persistence of T. aestivum ectomycorrhizae on roots of hazel (Corylus avellana L.) and oak (Quercus robur L.) and checked the host-species influence on community structure of ectomycorrhizal fungi. The study was conducted in an experimental plantation located in eastern Poland and established in 2008. We demonstrated that the number of fungal taxa was not significantly different between oak and hazel. However, the species composition differed between these two host trees. During the three-year study, we observed that species richness did not increase with the age of the plantation.

“…Belfiori et al (2012) found that the diversity of ectomycorrhizal species is lower in cultivated plantations than in natural habitats, higher in Tuber brumale -colonized plants than that of T. melanosporum -colonized plants (Belfiori et al 2012), and higher in productive plantations than in the nonproductive ones (De Miguel et al 2014). In the T. magnatum natural habitats, the most abundant fungal species belong to Thelephoraceae, followed by Sebacinaceae, Inocybaceae, and Russulaceae (Murat et al 2005; Leonardi et al 2013). In fact, Thelephoraceae are frequently found in mature truffle orchards, but the Hebeloma, Laccaria, and Russula species seem to associate with unproductive grounds (De Miguel et al 2014).…”

Macrofungi refers to all fungi that produce visible fruiting bodies. These fungi are evolutionarily and ecologically very divergent. Evolutionarily, they belong to two main phyla, Ascomycota and Basidiomycota, and many of them have relatives that cannot form visible fruiting bodies. Ecologically, macrofungi can be associated with dead organic matter, plants, and animals. Here we review our current understanding of population structure and biogeography of macrofungi associated with animals. Their interactions, functions, and patterns of coevolution are described and discussed. Our focus is on studies using molecular markers. Our analyses suggest that the types of fungi–animal associations play an important role in the structure of these animal-associated fungal populations.

“…Previous studies of this habitat have focused on the ECM fungal communities on roots (Murat et al, 2005;Bertini et al, 2006). Recently, the abundance and frequency of ECM species of four natural truffle grounds distributed along the Italian peninsula have been studied (Leonardi et al, 2013). In this study the authors examined more than 8000 root tips but T. magnatum ECM were never found, even in T. magnatum productive points.…”

Plant communities guarantee the functionality of terrestrial ecosystems, but they, in turn, depend on the microorganisms with which they are associated, especially those living in soil and roots. They provide most of the nitrogen and phosphorus taken up by plants, in temperate and boreal forests (Van der Heijden et al., 2008). Conservative estimates indicate that about 20,000 species of plants are completely dependent on soil symbiotic microorganisms for growth and survival, indicating the importance of soil microbes as regulators of plant richness on Earth (Van der Heijden et al., 2008).Among the various types of symbioses, the ectomycorrhizas (ECMs), which affect mainly the forest formations of temperate areas, are usually produced by fungal species capable of forming fruiting bodies (FBs) (Vogt et al., 1992). In the past, the structure of ectomycorrhizal (ECM) fungal communities was studied by FB surveys; this was then replaced by or coupled with root tip morphological analyses (Pacioni et al., 2001;Ashkannejhad and Horton, 2006). Molecular tools have been introduced and perfected over the past decades (Gardes et al., 1991;Gardes and Bruns, 1993), allowing for the identification, at least as a DNA sequence, of cryptic or nonfruiting ECM taxa. Molecular identification of ECMs is becoming the most common approach to study ECM communities in simplex and complex ecological systems (Mühlmann et al., 2008, Urban et al., 2008. Molecular characterization of ECMs coupled with FB surveying was also applied in several cases to study ECM communities. This double approach, in primary successional settings, makes ECM assemblages simple and gives a good correspondence between above and below ground ECM fungal communities (Nara et al., 2003); the ECM community is, in fact, dominated by a limited set of species that, after initial colonization, readily form sporocarps to disperse their spores to surrounding areas to widen their distribution (Nara, 2008). In contrast, in mature natural stands, there is a pervasive disconnection between aboveand below-ground ECM fungal communities (Gardes and Bruns, 1996). Smith et al. (2007) suggest that, in order to reach a complete overlap between FB and ECM fungal
