Rye has one of the most efficient group of genes for aluminium (Al) tolerance among cultivated species of Triticeae. This tolerance is controlled by at least two indepewndent and dominant loci (Altl and Alt3) located on chromosomes 6RS and 4R. We used two pooled DNA samples, one of Al-tolerant individuals and another of Al-sensitive plants from one F2 that segregated for the Altl locus. We also used two pooled DNA samples, one with genotypes 11 and another with genotypes 22 for the Lapl locus (leucin aminopeptidase) from another F2 progeny that segregated for this locus, located on the 6RS chromosome arm. We identified serveral RAPD markers associated with the pooled Al-tolerant plants and also with one of the bulks for the Lapl locus. The RAPD fragments linked to Altl and Papl genes were transformed into SCAR markers to confirm their chromosomal location and linkage data. |
