Distribution and haplotype diversity of WKS resistance genes in wild emmer wheat natural populations
Levels of genetic diversity and population genetic structure of a collection of 230 accessions of seven tetraploid Triticum turgidum L. subspecies were investigated using six morphological, nine seed storage protein loci, 26 SSRs and 970 DArT markers. The genetic diversity of the morphological traits and seed storage proteins was always lower in the durum wheat compared to the wild and domestic...
Head blight of wheat (FHB, scab) caused by Fusarium spp. is a severe fungal disease problem worldwide. Apart from yield and grain quality losses, the contamination of the harvest with toxic fungal metabolites, known as mycotoxins, is of serious impact. In spite of the fact that several sources for resistance against FHB have been found and utilized in hexaploid wheat, virtually no resistant tet...
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is one of the most important wheat diseases in the world. In this study, a single dominant powdery mildew resistance gene MlIW172 was identified in the IW172 wild emmer accession and mapped to the distal region of chromosome arm 7AL (bin7AL-16-0.86-0.90) via molecular marker analysis. MlIW172 was closely linked with the RFLP probe Xpsr...
Whole-genome scans with large number of genetic markers provide the opportunity to investigate local adaptation in natural populations and identify candidate genes under positive selection. In the present study, adaptation genetic differentiation associated with solar radiation was investigated using 695 polymorphic SNP markers in wild emmer wheat originated in a micro-site at Yehudiyya, Israel...
