A saturated SNP linkage map for the orange wheat blossom midge resistance gene Sm1.

SNP markers were developed for the OWBM resistance gene Sm1 that will be useful for MAS. The wheat Sm1 region is collinear with an inverted syntenic interval in B. distachyon.

Genetic analyses of BaMMV/BaYMV resistance in barley accession HOR4224 result in the identification of an allele of the translation initiation factor 4e (Hv-eIF4E) exclusively effective against Barley mild mosaic virus (BaMMV).

Based on a strategy combining extensive segregation analyses and tests for allelism with allele-specific re-sequencing an Hv-eIF4E allele exclusively effective against BaMMV was identified and closely linked markers for BaYMV resistance were developed. Soil-borne barley yellow mosaic disease is one of the most important diseases of winter barley. In extensive screenings for resistance, accession 'HOR4224' being resistant to three strains of Barley mild mosaic virus (BaMMV-ASL1, BaMMV-Sil, and BaMMV-Teik) and two strains of Barley yellow mosaic virus (BaYMV-1 and BaYMV-2) was identified.

Genomics-based high-resolution mapping of the BaMMV/BaYMV resistance gene rym11 in barley (Hordeum vulgare L.).

Soil-borne barley yellow mosaic virus disease, caused by different strains of Barley yellow mosaic virus (BaYMV) and Barley mild mosaic virus (BaMMV), is one of the most important diseases of winter barley (Hordeum vulgare L.) in Europe and East Asia. The recessive resistance gene rym11 located in the centromeric region of chromosome 4HL is effective against all so far known strains of BaMMV and BaYMV in Germany.

Genetic analyses of the host-pathogen system Turnip yellows virus (TuYV)-rapeseed (Brassica napus L.) and development of molecular markers for TuYV-resistance.

The aphid transmitted Turnip yellows virus (TuYV) has become a serious pathogen in many rapeseed (Brassica napus L.) growing areas. Three-years' field trials were carried out to get detailed information on the genetics of TuYV resistance derived from the resynthesised B.

Development of the single nucleotide polymorphism marker of the wheat Lr1 leaf rust resistance gene.

The range of publicly available data on plant nucleotide sequences opens a new possibility in the design of SNP assays. The purpose of this study was to identify point mutations in genomic sequences closely linked to the Lr1 leaf rust resistance gene, and to develop SNP markers based on primer extension (SNuPE) facilitating efficient marker-based selection procedures, e.g.
