Molecular and Functional Analysis of Resistance Expansion and Suppression for Alleles of the Powdery Mildew Resistance Gene Pm3 in Wheat
| 5 Abstract Developing high yielding and high quality varieties with broad-spectrum and durable disease resistance is the ultimate goal of crop breeding. Resistance (R) genes encoding proteins with nucleotide-binding site (NBS) and leucine-rich repeat (LRR) domains provide high levels of resistance, but this type of R genes usually only confers resistance to a subset of pathogen races. In addi...
متن کاملGenetic Diversity of the Pm3 Powdery Mildew Resistance Alleles in Wheat Gene Bank Accessions as Assessed by Molecular Markers
Genetic resources of crop plants are essential for crop breeding. They are conserved in gene banks in form of a large numbers of accessions. These accessions harbor allelic variants of agronomically important genes and molecular tools allow a rapid assessment of this allelic diversity. Here, we have screened a collection of 1005 wheat gene bank accessions for powdery mildew resistance and a mol...
متن کاملAllelic 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 کاملEfficiency of resistance genes in wheat to powdery mildew in some centers of disease incidence in Iran
Wheat powdery mildew caused by fungal pathogen Blumeria graminis f.sp. tritici is a destructive wheat disease, occurring in regions with cool and humid climates. In order to investigate the changes in pathogenicity of the disease and to identify the effective genetic source of resistance, a total of 29 wheat genotypes with different resistance major genes (Pm) were studied in two hotspots of Go...
