“…The removal of Mg 2+ from hydroxide sheet is also a possible pathway in the formation of 2:1 clay from the weathering of chlorite. Oxalate produced by ECM is an active agent of mineral weathering because of its high complexing capability (Cromack Jr. et al 1979;Robert and Berthelin 1986;Lapeyrie 1988). In a related study, we have found that verrucose and angular ornamentations in Piloderma ECM mostly appear to be crystals of Caoxalate complexes (Arocena et al 2001).…”

“…For example, Laccaria laccata inoculated on pine seedlings was able to weather phlogopite to vermiculite (Leyval and Berthelin 1991), and Paxillus involutus and Rhizopogon luteolus fungi have been reported to release the NH 4 + ions trapped in the interlayer of vermiculite (Paris et al 1994). Paxillus involutus has also been shown to produce oxalic acid by using bicarbonate ions (Lapeyrie 1988) whereas Hysterangium crassum on Douglas-fir was found to extract Fe and Al from andesite by providing high amounts of oxalate for chelation (Cromack Jr. et al 1979). Munir et al (2001) indicated that wood-rotting basidiomycetes oxidize glucose to oxalate in order to generate energy.…”

[91][92][93][94][95][96][97][98][99][100][101][102]. Soil properties of rhizosphere zones in coniferous forests are influenced by the presence of ectomycorrhizae. To elucidate the role of ectomycorrhizae (ECM) on the alteration of chemical and mineralogical properties of soils, soil pH, total C and N, cation exchange capacity, and the contents of mica, chlorite, and kaolinite, 2:1 type expandable clays, and amorphous minerals were compared in two soils, soils influenced by ectomycorrhizal fungi (ECS) and non-ectomycorrhizosphere soils (N-ECM) of Picea glauca x engelmannii (Moench.) Voss. Specifically, the two ECS soils were dominated by (1) Piloderma spp. (ECS-A) and (2) Inocybe lacera-like and Hebeloma-like morphotypes or where Piloderma spp. colonization was <1% (ECS-B). Our results showed that pH was lower in ECS compared to N-ECM samples. Total C and N were significantly higher in ECS soils than N-ECM samples. Cation exchange capacity as well as exchangeable K + , and Na + were higher in ECS compared to N-ECM soils. X-ray diffraction analysis showed that the amount of 2:1 expanding clays (vermiculite and smectite) was higher in ECS than N-ECM samples and results suggest that there is an enhanced transformation of mica and chlorite to 2:1 type expandable clays in ECS samples when compared to N-ECM samples. The differences in chemical and mineralogical properties between ECS and N-ECM soils, in our study, support earlier studies that show ectomycorrhizal fungi can alter the properties of soils in the rhizosphere zone.

“…Fungal sheaths were 2.4 to 6.4% enriched compared to the root core. Other studies have confirmed that sporophores of ectomycorrhizal fungi are often more enriched in 15 N than sporophores of saprotrophic fungi, whereas sporophores of saprotrophic fungi are almost always enriched in 13 C compared to sporophores of ectomycorrhizal fungi (Hobbie et al, 1999;2002;Kohzu et al, 1999;2000;Taylor et al, 2003;Trudell et al, 2004). Lilleskov et al (2002) demonstrated that isotope signatures reflect ecophysiological functions.…”

-• The development of truffles in the soil is not well understood. It is not known if a direct transfer of carbohydrates takes place between the host tree and the developing ascocarps through ectomycorrhizal structures or whether sporophores become independent from their hosts after several weeks or months and are able to use dead host tissues or soil organic matter as carbon (C) and nitrogen (N) sources.• To study saprophytic or symbiotic capacities of truffle ascocarps the natural abundance of 15 N and 13 C in foliage, wood, fine roots, mycorrhizae, fungal sporophores and soil were determined in a truffle orchard.• The processes of carbon and nitrogen allocation remained unchanged during the entire period of ascocarp development of Tuber melanosporum. From 13 C and 15 N natural abundance measurements, T. melanosporum, T. brumale and T. rufum did not exhibit saprotophic strategy during ascocarp development, which is contradictory to common statements found in handbooks regarding truffle cultivation. • Le développement des truffes dans le sol n'est pas encore bien compris. Les connaissances actuelles ne nous permettent pas de savoir s'il existe un transfert direct de sucres entre l'arbre hôte et les ascocarpes en développement via les structures ectomycorhiziennes, ou si les ascocarpes utilisent le carbone et l'azote directement issu de la matière organique du sol.• Nous avons mesuré l'abondance naturelle du 15 N et du 13 C dans le sol, les feuilles, les mycorhizes, le bois et les carpophores d'une truffière naturelle à chêne vert afin de déterminer la stratégie de la nutrition carbonée des ascocarpes.• Les processus d'allocation du carbone et de l'azote restent identiques pendant toute la phase de développement des ascocarpes de Tuber melanosporum. De ces mesures d'abondance naturelle du 15 N et du 13 C, il apparaît que T. melanosporum, T. brumale et T. rufum ne développent pas de stratégie saprophytique pendant le développement des ascocarpes, ce qui est en contradiction avec les idées habituellement véhiculées par les manuels de trufficulture 13 C / 15 N / Tuber melanosporum / ascocarpes / développement

“…We therefore assume that the growth of the unidentified fungus was enhanced by small amounts (0.25, 0.5, and 0.75 mL) of oxalic acid and inhibited by higher concentrations (1.0 and 2.0 mL) of the agent. This is supported by observations that some fungal species produce small amounts of oxalic acids themselves (Lapeyrie 1988).…”
