摘要: The knowledge of the host diversity in Tuber genus, an economically important group ectomycorrhizal fungi, is crucial importance for efficient cultivation system establishment. Centuries field observations as well scientific researches provided information on associations formed by these interesting fungi. Besides this, some recent works indicate that mycelia may be associated not only with roots woody plants traditionally considered hosts but also root tissues herbaceous and kinds soil organic matter. At same time, species genus tend to form scarce ectomycorrhizas. These facts suggest exploit auxiliary sources nutrition a commensalistic, parasitic, or necrotrophic manner. This would make concept life cycle more complex than just source via A possible change symbiosis result increase diversity, compared based recently accepted.
