Reference Assembly and Annotation of the Pyrenophora teres f. teres Isolate 0-1
Pyrenophora teres f. teres, the causal agent of net form net blotch (NFNB) of barley, is a destructive pathogen in barley-growing regions throughout the world. Typical yield losses due to NFNB range from 10 to 40%; however, complete loss has been observed on highly susceptible barley lines where environmental conditions favor the pathogen. Currently, genomic resources for this economically impo...
متن کاملCurrent 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 کاملDemethylase Inhibitor Fungicide Resistance in Pyrenophora teres f. sp. teres Associated with Target Site Modification and Inducible Overexpression of Cyp51
Pyrenophora teres f. sp. teres is the cause of net form of net blotch (NFNB), an economically important foliar disease in barley (Hordeum vulgare). Net and spot forms of net blotch are widely controlled using site-specific systemic fungicides. Although resistance to succinate dehydrogenase inhibitors and quinone outside inhibitors has been addressed before in net blotches, mechanisms controllin...
متن کاملCharacterizing the Pyrenophora teres f. maculata–Barley Interaction Using Pathogen Genetics
Pyrenophora teres f. maculata is the cause of the foliar disease spot form net blotch (SFNB) on barley. To evaluate pathogen genetics underlying the P. teres f. maculata-barley interaction, we developed a 105-progeny population by crossing two globally diverse isolates, one from North Dakota and the other from Western Australia. Progeny were phenotyped on a set of four barley genotypes showing ...
