The ema was characterized with antibodies against components of the plant cell wall; the ema contained hydroxyproline-rich glycoproteins and arabinogalactans/arabinogalactan proteins, both at a higher concentration close to the ehm. Haustoria with large vacuoles had the ema encased by additional layers. An electron-translucent inner layer deposited on top of the ema contained arabinogalactans/arabinogalactan proteins, hydroxyprolinerich glycoproteins, and callose. The inner layer was surrounded by an electron-translucent middle layer with numerous dark inclusions, rich in pectin and fucose bound to xyloglucans. Finally, a more electron-dense outer layer containing arabinogalactans/arabinogalactan proteins and hydroxyproline-rich glycoproteins encased the whole structure. These polysaccharides, with the exception of callose and un-esterified pectin, 'were also found in the plant Golgi apparatus. The polysaccharides were synthesized in the trans Golgi cisternae and secreted into the host-parasite interface. The secretory events seem to be coupled to endocytosis since numerous coated pits were found on the ehm too. The pits were elongated, sometimes formed tubules and the coat reacted with an antibody against plant clathrin. Our results suggest intensive membrane recycling around haustoria, together with the secretion of cell wall material, which in the case of more or less vacuolated haustoria seems to be responsible for encasement.</dcterms:abstract> <dcterms:title>Sequential deposition of plant glycoproteins and polysaccharides at the host-parasite interface of Uromyces vignae and Vigna sinensis</dcterms:title> <dc:creator>Stark-Urnau, Martina</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:29:35Z</dcterms:available> </rdf:Description> </rdf:RDF>
