Opis:
The aim of presented work was to identify of PCR amplifiedDNAfragments differentiating aluminium tolerant and sensitive forms of rye and to locate the markers on rye chromosomes. For identification of markers, the PCR system with semi-specific primers targeting intron-exon sequences of plant genes was applied. The modified method of bulked segregant analysis was used. The pooled DNAs of two or three F2 segregating populations were screened together with DNA of their parental inbred lines. Potential marker of tolerance gene was located on rye chromosomes using wheat/rye (Chinese Spring/Blanco) additional lines. The specific probes obtained from DNA fragments differentiating sensitive and tolerant forms of rye were hybridized to PCR amplified DNA fragments of sensitive and tolerant forms of rye and the set of wheat/rye addition lines. Independently of the method of digoxygenin labelling (primer extension or Taq polymerase reaction), the probes obtained showed similar hybridization patterns. The results of hybridisation of 21 probes prepared from 12 DNA fragments confirmed connection of selected DNA fragments with to aluminium tolerance or sensitivity. Most of these DNA fragments originated from tolerant forms of rye. Using this method it was possible to locate eight DNA fragments on rye chromosomes. Three DNA fragments hybridised to chromosome 4R, two DNA fragments to chromosome 6R and single DNA fragments to chromosomes 1R, 2R and 3R. Four DNA fragments indicating clear relationship with character studied were not located on particular chromosomes using this set of wheat/rye addition lines. Hybridisation of probes prepared from four DNA fragments revealed length polymorphism. Probes prepared from two DNA fragments were characterised as dominant markers. In other cases the type of marker (dominant/codominat) was not fully documented.

Opis:
Twelve DNA fragments amplified on templates of Triticum urartu, Aegilops speltoides and Aegilops squarrosa were separated, reamplified and used as digoxigenin-labelled probes. The species and genome specificity of probes was evaluated by Southern dot-blot hybridisation to Triticum durum, the donors of wheat genomes, rye and rye with introgressed wheat chromosome fragments. In comparison to labelled genomic DNA of T. durum, the probes obtained by labelling PCR-amplified fragments exhibited higher specificity to wheat genomes. Under the applied hybridisation conditions all probes showed different degree of cross-hybridisation to rye DNA. Some probes indicated quantitative difference in their specificity to wheat genomes, but generally the intensity of hybridisation to the genomes A, S and D was independent of the origin of an amplified fragment. Selected probes, used in dot-blot hybridisation system together with genomic DNA of T. durum, may increase the sensitivity of screening wheat chromosomal fragments introgressed to rye.
