Carbohydrate oxidation by the wheat smut fungus, Tilletia caries.
Extensive genetic studies (1) and limited nutritional investigations (2, 3) have been accomplished for the wheat smut organism, Tilletia caries, but information is lacking concerning its metabolism and enzyme systems. A more systematic approach to control might be realized by a fuller understanding of the nutrition and metabolism of the smut fungus. Studies designed to elucidate the pathway of ...
متن کاملKP4 to control Ustilago tritici in wheat: Enhanced greenhouse resistance to loose smut and changes in transcript abundance of pathogen related genes in infected KP4 plants
Ustilago tritici causes loose smut, which is a seed-borne fungal disease of wheat, and responsible for yield losses up to 40%. Loose smut is a threat to seed production in developing countries where small scale farmers use their own harvest as seed material. The killer protein 4 (KP4) is a virally encoded toxin from Ustilago maydis and inhibits growth of susceptible races of fungi from the Usti...
متن کاملThe Effect of Exogenous Phytohormones on Resistance of Wheat Calluses to Tilletia caries (D.C.) Tul. & C. Tul
The influence of exogenic hormones (indole-3-acetic acid (IAA), abscisic acid (ABA) and kinetin) on defense reaction of wheat (Triticum aestivum L.) calli to the bunt agent Tilletia caries (D.C.) Tul. & C. Tul. was studied. ABA and kinetin induced the oxalate oxidase activity, increased the Н2О2 level, decreased germination of fungi teliospores and induced on calli the occurrence of dense sites...
متن کاملA Dominant Gene for Resistance to Wheat Streak Mosaic Virus in Winter Wheat Line CO960293-2
Wheat streak mosaic (WSM), caused by Wheat streak mosaic virus (WSMV), is a devastating disease in wheat (Triticum aestivum L.) in the Great Plains of North America. Use of resistance is an effective and environmentally sound method to control the disease. In this study, six wheat genotypes were compared for their responses to WSMV infection under growth chamber conditions. The three resistant ...
متن کاملInheritance of Resistance to Bunt, Tilletia Tritici, in Sherman and Oro Wheat Hybrids.
In previous publications, the inheritance of resistance to bunt, TiCZetia tritici (Bjerk) Wint., in hybrids with eight resistant varieties of wheat, has been reported. The resistance of Martin (BRIGGS 1926), White Odessa (BRIGGS 1930b), Banner Berkeley (BRIGGS 1931), and Odessa (BRIGGS 193213) wheat varieties has been shown to result from the same dominant factor in each case. This factor has b...
