Interactions of saprotrophic fungi with tree roots: can we observe the emergence of novel ectomycorrhizal fungi?

Popis výsledku v původním jazyce

In this issue of New Phytologist, Smith et al. (pp. 747–755) re-address the question about the mode of interaction between tree roots and saprotrophic fungi. Roots of ectomycorrhizal (EcM) coniferous trees are known to interact with a large suite of different fungi. These interactions are typified by distinct anatomical and morphological characteristics and are specific for each type of interaction. The presence of root pathogens is characterized by various morphological changes to infected roots and leads to the rapid dieback of small roots. Root interior colonization by dark septate endophytes (that are most likely commensalists utilizing host resources) is rather limited in size so that they can live asymptomatically with their hosts. The EcM symbiosis is characterized by a distinct root shape, fungal penetration between cortical cells (the so called Hartig net), formation of a hyphal mantle encasing root tips and mycelia extending into the surrounding soil (van der Heijden et al., 2015). Anatomo-morphological features of the EcM symbiosis reflect its role in functioning as the plant root protection against pathogens, as well as the exchange zone for carbohydrates and mineral nutrients between the host plant and the mycobiont. If similar structures are observed in healthy roots, it is improbable that they are formed by fungi that have endophytic or pathogenic lifestyles.
