Allelic series of four powdery mildew resistance genes at the Pm3 locus in hexaploid bread wheat.
At the Pm3 locus in hexaploid wheat (Triticum aestivum), 10 alleles conferring race-specific resistance to powdery mildew (Blumeria graminis f. sp. tritici) are known. A cluster of genes encoding coiled-coil-nucleotide-binding site-leucine-rich repeat proteins spans the Pm3 locus on wheat chromosome 1A, and one member of this gene family has recently been identified as the Pm3b resistance gene....

متن کاملmlo‐based powdery mildew resistance in hexaploid bread wheat generated by a non‐transgenic TILLING approach
Wheat is one of the most widely grown cereal crops in the world and is an important food grain source for humans. However, wheat yields can be reduced by many abiotic and biotic stress factors, including powdery mildew disease caused by Blumeria graminis f.sp. tritici (Bgt). Generating resistant varieties is thus a major effort in plant breeding. Here, we took advantage of the non-transgenic Ta...
متن کاملSimultaneous Transfer of Leaf Rust and Powdery Mildew Resistance Genes from Hexaploid Triticale Cultivar Sorento into Bread Wheat
Wheat powdery mildew, caused by Blumeria graminis f. sp. tritici, and wheat leaf rust, caused by Puccinia triticina Eriks, are two important diseases that severely threaten wheat production. Sorento, a hexaploid triticale cultivar from Poland, shows high resistance to the wheat powdery mildew isolate E09 and the leaf rust isolate PHT in Beijing, China. To introduce resistance genes into common ...
متن کاملPowdery mildew resistance genes in wheat: verification of STS markers.
Five accessions of Aegilops speltoides and 67 European wheat cultivars (winter and spring) originating from the Czech Republic, Germany, Poland, Russia, Slovakia, United Kingdom, and 4 non-European wheat cultivars from Brazil and the USA were examined with molecular Sequence Tagged Site (STS) markers for resistance genes to powdery mildew: Pm 1, Pm 2, Pm 3 and Pm 13. All markers gave clear, rep...
