Identification of alleles at the gliadin loci Gli-U1 and Gli-M b 1 in Aegilops biuncialis Vis.

Identification of alleles at the gliadin loci Gli-U1 and Gli-M b 1 in Aegilops biuncialis Vis. The diversity of alleles at the gliadin loci Gli-U1 and Gli-M b 1 was studied in the tetraploid species Aegilops biuncialis (UUMbMb). The collection of 41 Ae. biuncialis accessions and F2 seeds obtained from five crosses served as the material used in this study. Gliadins were separated by acid polyacrylamide gel electrophoresis. To determine genomic affiliation (U or Mb) of components of Ae. biuncialis gliadin pattern, accessions of Ae. umbellulata and Ae. comosa were analyzed. In Ae. biuncialis accessions, 14 alleles were identified at the locus Gli-U1 and 12 alleles, at the locus Gli-M b 1. The results testify to a high degree of allele diversity at major gliadin-coding loci of homeologous group 1 chromosomes of Ae. biuncialis. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The diversity of alleles at the gliadin loci Gli-U1 and Gli-M b 1 was studied in the tetraploid species Aegilops biuncialis (UUMbMb). The collection of 41 Ae. biuncialis accessions and F2 seeds obtained from five crosses served as the material used in this study. Gliadins were separated by acid polyacrylamide gel electrophoresis. To determine genomic affiliation (U or Mb) of components of Ae. biuncialis gliadin pattern, accessions of Ae. umbellulata and Ae. comosa were analyzed. In Ae. biuncialis accessions, 14 alleles were identified at the locus Gli-U1 and 12 alleles, at the locus Gli-M b 1. The results testify to a high degree of allele diversity at major gliadin-coding loci of homeologous group 1 chromosomes of Ae. biuncialis.
