Carbohydrate and Lipid Metabolism During Germination of Uredospores of Puccinia graminis tritici.
Uredospores of Puccinia graminis (Pers.) tritici (Eriks. and Henn.) were uniformly labeled with (14)C by permitting the host (Triticum aestivum L.) to carry out photosynthesis in (14)CO(2) during the process of spore production by the obligate parasite. The use of (14)C labeled spores provided advantages in a study of the utilization of endogenous substrates at frequent intervals with small amo...
متن کاملGenetics of resistance to race TTKSK of Puccinia graminis f. sp. tritici in Triticum monococcum.
Race TTKSK (or Ug99) of Puccinia graminis f. sp. tritici possesses virulence to several stem rust resistance genes commonly present in wheat cultivars grown worldwide. New variants detected in the race TTKSK lineage further broadened the virulence spectrum. The identification of sources of genetic resistance to race TTKSK and its relatives is necessary to enable the development and deployment o...

متن کاملThe Nature of Cold - induced Dormancy in Urediospores of Puccinia graminis tritici Received for publication
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...
متن کاملGenetic Mapping of Stem Rust Resistance to Puccinia graminis f. sp. tritici Race TRTTF in the Canadian Wheat Cultivar Harvest.
Stem rust, caused by Puccinia graminis f. sp. tritici, is a destructive disease of wheat that can be controlled by deploying effective stem rust resistance (Sr) genes. Highly virulent races of P. graminis f. sp. tritici in Africa have been detected and characterized. These include race TRTTF and the Ug99 group of races such as TTKSK. Several Canadian and U.S. spring wheat cultivars, including t...
