Subject:
Triticum turgidum; cultivars; Puccinia graminis; genetic resistance; alleles; loci; disease resistance; rust diseases
Abstract:
... Few durable resistance genes have provided long-term effective control of stem rust (casual pathogen Puccinia graminis Pers. f. sp. tritici Eriks and E. Henn.), a destructive disease of wheat (Triticum ssp.). The most prominent gene, Sr2, derived from the tetraploid wheat, ‘Yaroslav Emmer’ (Triticum turgidum L.), contributes to the protection of many hexaploid cultivars worldwide. Additional durab ...

Abstract:
... A glycopeptide elicitor prepared from germ tubes of the rust fungus Puccinia graminis Pers. f. sp. tritici Erikss. & Henn (Pgt),as well as chitin oligosaccharides, chitosan, and methyl jasmonate (MJ) stimulated lipoxygenase (LOX) activity (E.C. 1.13.11.12) in wheat (Triticum aestivum) leaves. Immunoblot analysis using anti-LOX antibodies revealed the induction of 92- and 103-kD LOX species after P ...

To study the effect of incubation time and temperature on the phenotypic expression of rpg4, five barley genotypes with this resistance gene were infected with pathotype QCCJ of Puccinia graminis f. sp. tritici at the seedling stage, then subjected to various times of incubation at either 18-19 degrees C or 27-28 degrees C. Genotypes with rpg4 exhibited low (0, 0;, and 1), mesothetic (e.g. 3-210;, ...

Abstract:
... Over 90% of the germ tubes of Puccinia graminis tritici (wheat stem rust) and Puccinia hordei (barley brown rust) differentiate appressoria on encountering stomata. There has been controversy as to the role of host topographical signals in the highly precise and efficient induction of these infection structures over stomata by cereal rusts. In the present study, polystyrene replicas of microfabric ...

Abstract:
... In 1995, stem rusts of wheat and barley [Puccinia graminis f. sp. tritici] and oat [P. graminis f. sp. avenae] were light in eastern Canada, and in western Canada were confined mainly to the Red River Valley of Manitoba. Maximum severities of 20% developed in lines of susceptible wheat in nurseries, and there were no infections in commercial wheat fields. In some late-sown barley fields in Manitob ...

Abstract:
... Stem rust race Pgt-QCCJ was first found in the Great Plains of the United States in 1989, collected primarily from barley. This race became a major part of the Puccinia graminis f. sp. tritici population, even though it is virulent to only a few hard red winter wheat cultivars in the central Great Plains and to barley in the northern Great Plains. It threatens barley production in the northern Gre ...

Abstract:
... Pathogenesis-related expression of the two antifungal hydrolases beta-1,3-glucanase (EC 3.2.1.39) and chitinase (EC 3.2.1.14) was studied in wheat (Triticum aestivum L.) as part of the defence response to stem rust (Puccinia graminis f.sp. tritici; Pgt), mediated by the semi-dominantly acting resistance genes Sr5 and Sr24. Complete resistance (infection type 0), mediated by the Sr5 gene in cultiva ...

Abstract:
... Wheat stem rust overwintered in southern Louisiana, southern Texas, southwestern Georgia, northeastern Arkansas, and southwestern South Carolina in the winter of 1994-95. Wheat stem rust caused negligible yield losses in wheat in the United States. Races Pgt-TPMK and QCCJ made up 39 and 31% of all isolates, respectively. Race TPMK comprised 67% of isolates from farm fields. Race Pgt-QCCJ was most ...
