“…When B. graminis conidia germinate, the PGT penetrates the host epidermal cell (Kunoh et al, 1977(Kunoh et al, , 1979Kunoh, 1982), resulting in formation of papilla in the host cell immediately under the site of penetration (Kunoh et al, 1977). Suzuki et al (1998) have shown that B. graminis germlings secrete carboxymethyl cellulases and exo-␤-glucanases during germination.…”

“…Kunoh et al (1977) showed that conidia of B. graminis have a unique germination pattern whereby they form at least two germ tubes. A short, non-appressodal germ tube always emerged about 2 h before the appressorial germ tube, and the two types of germ tube were readily distinguished soon after emergence (Kunoh et al, 1977). The first remained short (ca.…”

Meguro, A., Fujita, K., Kunoh, H., Carver, T. L. W., Nicholson, R. L. (2001). Release of the extracellular matrix from conidia of Blumeria graminis in relation to germination.? Mycoscience, 42, 201-209.The release of extracellular matrix (ECM) and the emergence of germ tubes from conidia ofBlumeria graminis were studied by light microscopy and micromanipulation. More prompt and frequent ECM release was confirmed on an artificial hydrophobic substratum than on an artificial hydrophilic substratum. Conidia initially incubated on the hydrophilic substratum were transferred by micromanipulation to either the hydrophobic or the hydrophilic substrata. Immediately after transfer onto the hydrophobic substratum, 75% of conidia released ECM, whereas only 16% did so upon transfer to the hydrophilic substratum. Conidia transferred onto the hydrophobic substratum produced a primary germ tube (PGT) more promptly and frequently than those transferred to the hydrophilic substratum. Thus, conidia recognize and respond to substratum hydrophobicity perhaps immediately after contact. When inoculated onto either isolated barley cuticle or the hydrophobic artificial substratum, 2/3 of the conidia produced a PGT from their polar regions. By contrast, on the hydrophilic substratum 2/3 of conidia did so from the side region. These results show that substratum hydrophobicity affects the location of PGT emergence from conidia. Furthermore, the study indicates that very rapid recognition of surface hydrophobicity by conidia promotes ECM release and this in turn may influence the location of PGT emergence.Peer reviewe
