Genetic differentiation in Pyrenophora teres populations measured with AFLP markers
Mycological Research, 2007The genetic structure and occurrence of mating types and forms of Pyrenophora teres, the causal agent of net blotch on barley, was studied among 278 isolates collected from the northern hemisphere and from Australia. Genetic differentiation was high (F(CT) 0.238, P=0.002) between P. teres f.

The barley net blotch pathogen Pyrenophora teres occurs in two forms, evident as spot (P. teres f. maculata) or net (P. teres f. teres) type symptoms. The two forms can be difficult to differentiate based on disease symptoms or spore morphology. Here we report nine simple sequence repeat markers that reveal differences between the two forms, providing ...

Initial characterisation of phytotoxic proteins isolated from Pyrenophora teres
Physiological and Molecular Plant Pathology, 2008Pyrenophora teres, the causal agent of net blotch of barley (Hordeum vulgare L.), induces distinctive long dark brown lesions (the net form) or dark brown spots (the spot form), both with surrounding chlorosis. Proteins isolated from P. teres f. teres (the net form) and P. teres f. maculata (the spot form) induce host-specific necrosis.

Quantitative Resistance toPyrenophora teresf.teresin Barley
Phytopathology, 1992Resistance to the net blotch pathogen Pyrenophora teres f. teres was studied in seven barley genotypes using four criteria: 1) infection response (size and type of lesion), 2) area under the disease progress curve (AUDPC), 3) terminal severity (TS), and 4) apparent infection rate (r). The susceptible check, Kombar, and resistant check, Tifang, differed

Pathotype Diversity ofPyrenophora teresf.tereson Barley
Phytopathology, 1992From 91 isolates collected in California, 13 pathotypes of Pyrenophora teres f. teres, the causal organism of net blotch of barley, were identified on 22 differential barley genotypes. Pathotype 3-10-15-19-21 (numbers correspond to the differential barley hosts that exhibit a high infection response [HIR] to this pathotype) was most prevalent ...

Analysis of Pyrenophora Teres (Died.) Drechs. Population from Slovakia
1997Pyrenophora teres (Died.) Drechs. is the causal agent of net blotch of barley that has become in the last ten years one of the most widespread barley leaf mycoses in Slovakia due to the absence of resistent cultivars in present local assortment. From the viewpoint of new biological material creation with resistance to this facultative parasite the ...
