Allium porrum, Zea mays, Trifolium repens, and Nicofiana tabacum plants were chosen as representatives of monocots and dicots with different wall structures. Analyses were performed on root tissues in the presence and absence of arbuscular mycorrhizal fungi. A differential localization of the two cell wall epitopes was found between tissues and between species: for example, in leek, CCRC-M1 labeled epidermal and hypodermal cells, whereas CCRC-M7 labeled cortical cells only. Clover walls were labeled by both McAbs, whereas maize and tobacco were only labeled by CCRC-M7. In the presence of the arbuscular mycorrhizal fungi, labeling was additionally found in an apoplastic compartment typical of the symbiosis (the interface) occurring around the intracellular hyphae. Epitopes binding both McAbs were found in the interfacial material, and their distribution mirrored the pattern found in the host cell wall. These findings demonstrate that the composition of the interface zone in a fungus-plant symbiosis reflects the composition of the wall of the host cell.</dcterms:abstract> <dc:contributor>Hahn, Michael G.</dc:contributor> <dc:format>application/pdf</dc:format> <dc:language>deu</dc:language> <dcterms:issued>1996</dcterms:issued> <dc:creator>Hahn, Michael G.</dc:creator> <dc:creator>Faccio, Antonella</dc:creator> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> </rdf:Description> </rdf:RDF>
