Involvement of fimbriae in fungal host-mycoparasite interaction

Quantification of substratum contact required for initiation of Colletotrichum graminicola appressoria

“…It is unclear how the germ tubes were able to sense the bottom of such narrow (0.5-0.6 lm wide) inter-pillar gaps since they did not generally grow into these voids as could be concluded from SEM. Several possibilities exist: sensing might, for example, involve the ECM or fungal fimbriae (Apoga and Jansson, 2000;Castle et al, 1996;Day and Gardiner, 1987;Rghei et al, 1992) extending into these regions. An alternative explanation is that involving the possible diffusion of cell metabolites away from the germ tube apex.…”

Visualization and characterization of the extracellular matrix of Bipolaris sorokiniana

“…Celerin et al (1996) claimed that fimbriae of Microbotryum violaceum were composed of fungal collagen. Fimbriae may function as the first interface in cell fusion processes such as mating and anastomosis (Castle, Stocco & Boulianne, 1996) and may also play an important role in pathogenesis, in particular as adhesion structures responsible for attaching the pathogen to its host (Rghei, Castle & Manocha, 1992).…”

Use of Molecular Cytology to Study the Structure and Biology of Phytopathogenic and Mycorrhizal Fungi

“…Antisera raised against fimbrial proteins react along the length of the fimbriae (Svircev et al, 1986) and show that the protein moiety is highly conserved amongst fungal species, cross-reacting with the shorter fibrils on the surface of ascomycetous yeasts (Gardiner et al, 1982). The Ustilago antiserum also cross-reacts with polypeptides of relative molecular weight 57-64 kDa forming fimbriae on the surface of Mortierella pusilla, Mortierella candelabrum, and Phascolomyces articulosus (Rghei et al, 1992). Binding of the Ustilago antiserum to the surface of these fungal hosts inhibits their recognition by the mycoparasite Piptocephalis virginiana.…”
