The surface of ectomycorrhizal roots and the interaction with ectomycorrhizal fungi

Abstract:

Most of the trees in the temperate and alpine regions live in symbiosis with root fungi forming ectomycorrhizas. Ectomycorrhizas (ECM) display a very specified cellular organization.A fungal sheath covers the root surface and the hyphae invade intercellularly between the root cortical cells establishing the so-called Hartig net. The hyphal sheath is formed in a species-specific manner (Agerer 1998), but the architecture of the Hartig net is similar in all the ectomycorrhizas, independent of plant and fungal species (Blasius et al. 1986, Kottke and Oberwinkler 1987, 1989). Establishing the Hartig net, hyphal growth undergoes important changes. The hyphae invade as multi-branched, fan-like lobes in intimate juxtaposition, starting at the root surface and finally covering the root cortical cells in a dense mono-layer. © Springer-Verlag Berlin Heidelberg 2004, 2008.
