Identification of wheat gene Sr35 that confers resistance to Ug99 stem rust race group.
Wheat stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), is a devastating disease that can cause severe yield losses. A previously uncharacterized Pgt race, designated Ug99, has overcome most of the widely used resistance genes and is threatening major wheat production areas. Here, we demonstrate that the Sr35 gene from Triticum monococcum is a coiled-coil, nucleotide-binding, leucine...
متن کاملAdditions to the rust mycobiota of Iran
In the present study, two species of rosaceous rust fungi are reported from Iran. Ochropsora ariae is newly reported for Iranian rust mycobiota. This is the first report of a member of the genus Ochropsora from Iran. Kuehneola uredinis is reported for the second time from Iran since its first report in 1958 under the name K. albida. Pyrus boissieriana</em...

et al., 1981) and timothy (Phleum pratense L.; Braverman, 1966; Nielson and Dickson, 1958). In addition, Genetic resistance to stem rust (caused by Puccinia graminis several cultivars of perennial ryegrass (Lolium perenne Pers.:Pers. subsp. graminicola Z. Urban) could reduce the need for fungicides to control the disease in tall fescue [Lolium arundinaceum L.) with reduced susceptibility to ste...
متن کاملRust-sugar Cane Interaction - Possible Application of Serological Methods for Early Selection to Rust Disease
Antigens and antisera from in vitro cultures of Puccinia melanocephala Sydow, uredospores collected from the field and sugar cane varieties were obtained. Cross-reactions were detected between the fungi and plants by counterimmunoelectrophoresis, immunoelectrophoresis and indirect ELISA. The last technique detected more antigenic relationships with the susceptible plants. This result may be use...
متن کاملMolecular Cytogenetic Characterization of two Triticum–Secale–Thinopyrum Trigeneric Hybrids Exhibiting Superior Resistance to Fusarium Head Blight, Leaf Rust, and Stem Rust Race Ug99
Fusarium head blight (FHB), leaf rust, and stem rust are the most destructive fungal diseases in current world wheat production. The diploid wheatgrass, Thinopyrum elongatum (Host) Dewey (2n = 2x = 14, EE) is an excellent source of disease resistance genes. Two new Triticum-Secale-Thinopyrum trigeneric hybrids were derived from a cross between a hexaploid triticale (X Triticosecale Wittmack, 2n...
