“…T. timopheevii for the identification of introgression segment on chromosome 2B of wheat variety LongReach Lancer [56] . Cytological methods were widely used for the detection of timopheevii introgression signals in the wheat [57] , [58] . Wild emmer accessions were previously classified into wild race I ( T. turgidum ssp.…”

“…tauschii germplasm [46][47][48]. In addition, the majority of gene introgressions of agronomically important traits from wild related species occurred in the chromosomes of the D-genome and the presence of D chromosomes increases the success of distant interspecific and intergeneric introgressions [49][50][51][52][53][54][55]. To increase the efficiency of introgressions from the D-genome, an intensive study of its molecular genetic structure using the NGS approaches is carried out in order to map and develop markers for genes of agronomical important traits [33,56].…”

The low diversity of the D-subgenome of bread wheat requires the involvement of new alleles for breeding. In grasses, the allelic state of Growth Regulating Factor (GRF) gene is correlated with nitrogen uptake. In this study, we characterized the sequence of TaGRF-2D and assessed its diversity in bread wheat and goatgrass Aegilops tauschii (genome DD). In silico analysis was performed for reference sequence searching, primer pairs design and sequence assembly. The gene sequence was obtained using Illumina and Sanger sequencing. The complete sequences of TaGRF-2D were obtained for 18 varieties of wheat. The polymorphism in the presence/absence of two GCAGCC repeats in 5' UTR was revealed and the GRF-2D-SSR marker was developed. Our results showed that the alleles 5' UTR-250 and 5' UTR-238 were present in wheat varieties, 5' UTR-250 was presented in the majority of wheat varieties. In Ae. tauschii ssp. strangulata (likely donor of the D-subgenome of polyploid wheat), most accessions carried the 5' UTR-250 allele, whilst most Ae. tauschii ssp. tauschii have 5' UTR-244. The developed GRF-2D-SSR marker can be used to study the genetic diversity of wheat and Ae. tauschii.
