ABSTRACT A major gene for resistance to wheat powdery mildew (Blumeria graminis f. sp. tritici = Erysiphe graminis f. sp. tritici) has been successfully transferred into hexaploid common wheat (Triticum aestivum, 2n = 6x = 42, AABBDD) from wild einkorn wheat (Triticum monococcum subsp. aegilopoides, 2n = 2x = 14, AA). NC96BGTA5 is a germ plasm line with the pedigree Saluda x 3/PI427662. The res...
Identification of Glucitol (Sorbitol) and Ribitol in a Rust Fungus, Puccinia graminis f. sp. tritici
Stem rust is a disease of wheat caused by basidiomycete Puccinia graminis f. sp. tritici (Pgt). Emergence new populations the pathogen and their spread over world calls for growing cultivars with lasting resistance. Knowledge resistance gene composition in local fields together knowledge global movements races crucial. Present study focused on using molecular markers to detect eight genes 58 en...
When air-dry urediospores of the wheat stem rust, Puccinia graminis f. sp. tritici, are exposed to temperatures below freezing, their germinability is markedly reduced, even after prolonged thawing at room temperature. Germinability is fully restored by a brief heat-shock or by vapor phase hydration. We have found that this "cold dormancy" cannot be reversed once the spores contact liquid water...
