Genetic mapping of Pyrenophora teres f. teres genes conferring avirulence on barley
Fungal Genetics and Biology, 2007A Pyrenophora teres f. teres cross between isolates 0-1 and 15A was used to evaluate the genetics of avirulence associated with barley lines Canadian Lake Shore (CLS), Tifang, and Prato. 15A is avirulent on Tifang and CLS, but virulent on Prato. Conversely, 0-1 is avirulent on Prato, but virulent on Tifang and CLS.

Genetic analysis of virulence in the Pyrenophora teres f. teres population BB25 × FGOH04Ptt-21
Fungal Genetics and Biology, 2017Pyrenophora teres f. teres is the causal agent of net form net blotch (NFNB) of barley. In order to map the genetics of avirulence/virulence in P. teres f. teres, a fungal population was developed using P. teres f. teres isolates BB25 (Denmark) and FGOH04Ptt-21 (North Dakota, USA) due to these two isolates differing in virulence on several common ...

POPULATION STRUCTURE OF THE BARLEY PATHOGEN PYRENOPHORA TERES f. TERES IN LITHUANIA
Journal of Plant Pathology, 2012The amplified fragment length polymorphism (AFLP) technique was used to study the genetic structure of Pyrenophora teres, the causal agent of barley net blotch disease. Samples were collected from five locations in Lithuania in 2008. All 145 isolates had unique AFLP patterns.

Assessment of resistance in barley to Pyrenophora teres and Pyrenophora japonica
Crop Protection, 1992Abstract Nine barley cultivars (cvs) were evaluated for their reactions to two leaf spot fungi, Pyrenophora teres and Pyrenophora japonica . The type of lesions occurring on headed plants after inoculation was a reliable indicator of susceptibility or resistance of cvs to net blotch and spot-type net blotch in the field.

Infection by Pyrenophora teres f. teres (Ptt) or P. teres f. maculata (Ptm), the causal agents of the net and spot forms of net blotch of barley, respectively, can result in significant yield losses. The genetic structure of a collection of 128 Ptt and 92 Ptm isolates from the western Canadian provinces of Alberta (55 Ptt, 27 Ptm), Saskatchewan (58 Ptt,

Fungal growth, proteinaceous toxins and virulence of Pyrenophora teres f. teres on barley
Australasian Plant Pathology, 2014Pyrenophora teres f. teres (Ptt) causes net form net blotch (NFNB), an important disease of barley, but isolates of Ptt vary in their ability to cause symptoms on susceptible cultivars. Ptt isolates with different virulence were used to compare conidial germination and fungal growth on the barley cultivar ‘Sloop’.

Non radioactive Differential Display Reverse Transcription- PCR (DDRT-PCR) was used to screen molecular variants at expression level in Pyrenophora graminea and Pyrenophora teres, grown in vitro with glucose or plant cell walls as carbon sources. Several differential transcripts from both species were identified, either constitutive or induced by ...

Pyrenophora teres, an agent causing wheat leaf spot
Microbiology, 2010In 2007-2008, the barley net blotch agent Pyrenophora teres was found to infect spring wheat in northwestern Russia, causing symptoms similar to wheat tan spot caused by P. tritici-repentis. The frequency of occurrence of P. teres on spring wheat cultivars was 12-29%. P. teres isolates were more virulent to some wheat cultivars than P. tritici-repentis

Pyrenophora Teres’ de Patojenik Varyasyon
2015Pyrenophora teres’ in neden olduğu ağ benek hastalığı dünyada olduğu gibi ülkemizde de arpa hastalıkları arasında kaliteyi ve verimi etkileyen önemli bir hastalıktır. Hastalığa sebep olan patojenin iki tipi bulunmaktadır. Pyrenophora teres Drechs. f. teres Smedeg. ağ tipi belirtilere, P.teres. f. maculata Smedeg. nokta tipi belirtilere neden olmaktadır.

Characterization of virulence in Pyrenophora teres f. maculata
2021Net blotches are common foliar diseases of barley caused by the fungus Pyrenophora teres. There are two forms of net blotch. The net form net blotch (NFNB), caused by P. teres f. teres (Ptt) and the spot form net blotch (SFNB), caused by P. teres f. maculata (Ptm). Spot form net blotch is a major foliar disease of barley worldwide. In Australia, annual
