Genetic diversity for the alleles of gliadin-coding loci was studied with 465 durum wheat accessions from 42 countries. A total of 108 alleles were identified for four loci; 60 alleles were described for the first time. Broad diversity of rare gliadin-coding alleles was observed. The highest genetic diversity was characteristic of durum wheat accessions from the Middle East, Trans-Caucasia, the Pyrenean Peninsula, and the Balkans. Two genetically isolated ancient branches of durum wheat were isolated. A "southern" branch included mostly accessions from the Mediterranean region, the Middle East, and Trans-Caucasia. A "northern" branch included Russian and Ukrainian durum wheat accessions and varieties obtained on their basis. An additional group included durum wheat accessions that had been obtained in several past decades on the basis of the material of international breeding centers (CIMMYT and ICARDA) and had low genetic diversity. © Pleiades Publishing, Inc., 2010.

Based on legume genome syntheny, the nucleotide sequence of Srlk gene, key role of which in response to salt stress was demonstrated for the model species Medicago truncatula, was identified in the major forage and siderate crop alfalfa (Medicago sativa). In twelve alfalfa samples originating from regions with contrasting growing conditions, 19 SNPs were revealed in the Srlk gene. For two nonsynonymous SNPs, molecular markers were designed that could be further used to analyze the association between Srlk gene nucleotide polymorphism and the variability in salt stress tolerance among alfalfa cultivars. © 2014 Pleiades Publishing, Inc.
