Molecular mapping of segregation distortion loci in Aegilops tauschii.
Distorted segregation ratios of genetic markers are often observed in progeny of inter- and intraspecific hybrids and may result from competition among gametes or from abortion of the gamete or zygote. In this study, 194 markers mapped in an Aegilops tauschii F2 population were surveyed for distorted segregation ratios. Region(s) with skewed segregation ratios were detected on chromosomes 1D, 3...
متن کاملCharacterization of genetic variation among accessions of Aegilops tauschii
* Author for correspondence: Agronomy and Plant Breeding Department, Agricultural College, University of Tehran, Karaj, Iran. Tel: 02612246074, Fax: 02612227607, Email: [email protected]. Abstract. The application of AFLPs, and SSRs to examine genetic relationships in the 54 accessions of Aegilops tauschii from 5 countries was investigated. A total of 256 (234 polymorphic) and 224 (219 polymorp...
متن کاملCharacterization of the CCT family and analysis of gene expression in Aegilops tauschii
Flowering is crucial for reproductive success in flowering plant. The CCT domain-containing genes widely participate in the regulation of flowering process in various plant species. So far, the CCT family in common wheat is largely unknown. Here, we characterized the structure, organization, molecular evolution and expression of the CCT genes in Aegilops tauschii, which is the D genome donor of...
متن کاملEvaluation and characterization of high-molecular weight 1D glutenin subunits from Aegilops tauschii in synthetic hexaploid wheats
The high-molecular weight (HMW) glutenin subunits of bread wheat are major determinants of end-use quality. The objective of this study was to determine the 1Dx and 1Dy subunits present in 43 synthetic hexaploid wheat (SHW) lines derived by crossing durum ‘Langdon’ to 43 Aegilops tauschii accessions. Protein samples were initially electrophoresed multiple times on SDS-PAGE gels to arrange subun...
متن کاملCharacterization of novel LMW-GS genes at Glu-D3 locus on chromosome 1D in Aegilops tauschii.
The objectives of this study were to clarify the relationship between LMW-GS Glu-D3 gene of Ae. tauschii registered in GenBank and the six Glu-D3 genes including 12 allelic variants of common wheat characterized in our previous studies, and identify novel Glu-D3 genes and haplotypes from Ae. tauschii using gene specific PCR amplification. By searching the NCBI database, 13 LMW-GS genes/pseudoge...
