Abstract

Molecular genetic characterization of the Wx-B1e allele identified by the authors of the study in the common wheat cultivar Korotyshka was performed. The 804-bp Wx-B1e fragment was cloned and sequenced. Comparison of the sequence obtained with that for the wild-type allele of common wheat (Wx-B1a) demonstrated that Wx-B1e carried the 34-bp insertion, 8-bp deletion, and 23 nucleotide substitutions. BLAST analysis revealed the highest homology with the nucleotide sequences of Wx genes from Triticum spelta and Triticum durum. The amplification variants of four Wx-B1 molecular markers, applied worldwide for testing the collections for different Wx allelic variants, are demonstrated.
