A Mycosphaerella species as the Ascogenous state of Septoria tritici Rob. and Desm.

Discovery of a functional Mycosphaerella teleomorph in the presumed asexual barley pathogen Septoria passerinii

“…S. tritici, the anamorph of M. graminicola, was first reported in 1842. The teleomorph was discovered in 1894, but it was not linked to S. tritici until 1972 (Sanderson, 1972). Once this link was made, the emphasis of research efforts extended from epidemiological studies (Royle and Shaw, 1986;Shaw and Royle, 1993) to studies on population genetics (McDonald et al, 1995(McDonald et al, , 1999 and host-pathogen interactions (Kema et al, 1996a(Kema et al, ,b, 2000.…”

Weather Conditions Associated with the Release and Dispersal of Zymoseptoria tritici Spores in the Argentine Pampas Region

“…For AV identification, only two-cell, elliptical, hyaline spores of 9-16 (18) × 2.5-4.5 휇m [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] were considered; the viability of the airborne spores was determined by recording their germination and formation of secondary conidia directly on Vaseline.…”

“…Pseudothecia mature during winter and remain viable into early spring. Only 30 min of moistening stubble is necessary for ascospore release and dispersal [7]. Hunter et al [8] suggested that airborne ascospore plays the major role in epidemiology during the growing season and, together with splash dispersal spores, both have implications for the forecasting of the disease.…”

Isolation and Characterization of the Mating-Type Idiomorphs from the Wheat Septoria Leaf Blotch Fungus Mycosphaerella graminicola

“…The loculoascomycete Mycosphaerella graminicola (Fuckel) J. Schrö t. in Cohn causes septoria tritici leaf blotch, which is the major wheat disease in northwestern Europe. The asexual form, Septoria tritici, was described more than 150 years ago, whereas the teleomorph was identified in the early 1970s (Sanderson, 1972). Since then, ascospores have been found to be the most important drivers of the onset of septoria tritici leaf blotch epidemics in major production areas around the world (Shaw and Royle, 1989).…”
