Marker Assisted Transfer of Two Powdery Mildew Resistance Genes PmTb7A.1 and PmTb7A.2 from Triticum boeoticum (Boiss.) to Triticum aestivum (L.)
Powdery mildew (PM), caused by Blumeria graminis f. sp. tritici, is one of the important wheat diseases, worldwide. Two PM resistance genes, designated as PmTb7A.1 and PmTb7A.2, were identified in T. boeoticum acc. pau5088 and mapped on chromosome 7AL approximately 48cM apart. Two resistance gene analogue (RGA)-STS markers Ta7AL-4556232 and 7AL-4426363 were identified to be linked to the PmTb7A...
متن کاملAssociation mapping for resistance to powdery mildew in oriental tobacco (Nicotiana tabaccum L.) germplasm
Powdery mildew caused by Erysiphe cichoracearum is an important fungal disease which threatens tobacco (Nicotiana tabacum L.) production. The objective of this study was to determine DNA markers linked to genomic regions associated with resistance to powdery mildew in tobacco through the association mapping approach. Seventy tobacco geno-types were fingerprinted using 26 simple se-quence repeat...
متن کاملApplication of Glycerol for Induced Powdery Mildew Resistance in Triticum aestivum L.
Previous work has demonstrated that glycerol-3-phosphate (G3P) and oleic acid (18:1) are two important signal molecules associated with plant resistance to fungi. In this article, we provide evidence that a 3% glycerol spray application 1-2 days before powdery mildew infection and subsequent applications once every 4 days was sufficient to stimulate the plant defense responses without causing a...
متن کاملFine Mapping of Two Wheat Powdery Mildew Resistance Genes Located at the Cluster.
Powdery mildew caused by (DC.) f. sp. () is a globally devastating foliar disease of wheat ( L.). More than a dozen genes against this disease, identified from wheat germplasms of different ploidy levels, have been mapped to the region surrounding the locus on the long arm of chromosome 7A, which forms a resistance ()-gene cluster. and from einkorn wheat ( L.) were two of the genes belonging to...
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...
