[Chromosomal localization of the speltoidy gene, introgressed into bread wheat from Aegilops speltoides Tausch., and its interaction with the Q gene of Triticum spelta L].

Abstract excerpt

The differences between bread wheat (Triticum aestivum L.) and spelt (Triticum spelta L.) in the shape of the spike and threshing character are determined by the allelic status of one major Q gene, mapped to the long arm of chromosome 5A. This gene is a member of the APETALA2 family of transcription factors and plays an important role in domestication of wheat. In the present study, using monosomic analysis, we...
