Current Virulence of Pyrenophora teres on Barley in Western Australia
Net blotch, caused by Pyrenophora teres Drechs. (anamorph: Drechslera teres (Sacc.) Shoemaker), is a prominent foliar disease of barley (Hordeum vulgare L. emend. Bowden) in Western Australia (19,46), as well as elsewhere in the world (13,28,31,34,39,41). Two types of leaf symptoms are associated with the net blotch disease: the net type, caused by P. teres f. teres, which causes horizontal and...
متن کاملGenetic mapping of Pyrenophora teres f. teres genes conferring avirulence on barley.
A 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. Avirulence:virulence on Tifang and CLS segregated 1:1, whereas avirulence:virule...
متن کاملEfficiency of IRAP and ITS-RFLP marker systems in accessing genetic variation of Pyrenophora graminea
The usefulness of IRAP (inter-retrotransposon amplified polymorphism) and ITS-RFLP (restriction of PCR-amplified internal transcribed spacers of the rDNA) markers in the analysis of 39 Pyrenophora graminea isolates was determined. Each marker system could discriminate between all of the isolates in detecting polymorphism, albeit with variable efficiency. IRAP and ITS-RFLP produced 85% and 77% p...
متن کاملVirulence Phenotyping and Molecular Characterization of a New Virulence Type of Pyrenophora tritici-repentis the Causal Agent of Tan Spot
Pyrenophoratritici-repentis is the causal agent of tan spot. According to their ability to produce necrosis and/or chlorosis on a set of four differential bread wheats, the isolates of this fungus are currently grouped into eight races. When durum wheat genotypes were added to the differential set, a new virulence type was identified in Algeria. The isolates showing this virulence pattern are u...
متن کاملDetection and Phylogenetic Characterization of Virulence Genes of Escherichia coli Associated with Canine Urinary Tract Infections in India
BACKGROUND: Escherichia coli (E.coli) is one of the most common and important causative bacterium of urinary tract infections (UTIs) in both dogs and humans. OBJECTIVES: This study aimed to identify virulence genes and a phylogenetic group of E. coli isolated from the urine of dogs suffering from UTIs. METHODS: <em...
