Fungi in ectomycorrhizal associations of silver fir ( Abies alba Miller) in Central Italy

Ectomycorrhizal fungal communities of silver-fir seedlings regenerating in fir stands and larch forecrops

“…On the other hand, C. geophilum is a common, dominating fungal component of the ectomycorrhizas of many tree species (Aučina et al 2011;Teste et al 2009), silver-fir including (Cremer et al 2009;Ważny 2014). Even though the investigation was conducted in A. alba natural range, we did not observe L. salmonicolor, known to be specific to A. alba, which has been already documented in the Carpathians (Ważny 2014), the Apennines (Comandini et al 1998(Comandini et al , 2001, and Tuscany (Laganà et al 2002). This is the first report concerning ECM of A. alba seedlings regenerating in larch forecrops using molecular approaches.…”

“…A similar ECM morphotype richness (48) was found on mature silver-fir trees in Apennines (Italy) by Comandini et al (2001). On seedlings from the same locality, these authors (Comandini et al 1998) Hijii (1999, 2004) revealed 37 morphotypes from Abies firma seedlings (SI = 142). The relative abundance of fir symbionts documented in fir stands in our previous study and presented here was comparable, the relative abundance of fir symbionts documented in pine (Ważny 2014), and larch forecrops was completely different.…”

Ectomycorrhizal communities associated with silver fir seedlings (Abies alba Mill.) differ largely in mature silver fir stands and in Scots pine forecrops

“…ECM fungi colonize new seedlings and protect them against root disease ensuring healthy seedling growth (Marx 1969) and are involved in the process of regeneration of the plants and sustainability of ecosystems; this increases seedling survival of the silver fir (Perry et al 1989). The current knowledge of silver fir symbionts is predominantly based on morphological and anatomical descriptions of ectomycorrhizas (Agerer 1987(Agerer -2007Berndt et al 1990;Comandini et al 1998Comandini et al , 2001De Román et al 2005;Dominik 1961;Farfał 2008;Kowalski 1982Kowalski , 2008Kowalski et al 1996;Pachlewski 1955;Stępniewska and Rębisz 2004) and fungal fruiting bodies (Laganà et al 1999(Laganà et al , 2002. Few molecular investigations of the ECM symbionts that associate with silver fir seedlings appear in the literature (Cremer et al 2009;Eberhardt et al 2000;Smutek et al 2010;Ważny 2011).…”

Uniting Tricholoma sulphureum and T. bufonium

“…In the last few years, we have undertaken a study of the hitherto little-known ectomycorrhizas of silver fir (Abies alba) (Comandini, Pacioni & Rinaldi 1998, 2001, Eberhardt et al 2000, an ecologically important tree found in many mountainous regions of central and southern Europe. During our investigations, we distinguished and characterised more than 60 ectomycorrhizal morphotypes on silver fir, the vast majority of which had never been described before and were formed by unidentified mycobionts (Comandini et al 2001).…”
