Polyploidy is the major mechanism of speciation in flowering plants. All genomes of ancient species that are the progenitors of extant plant species experienced polyploidization. Three consecutive stages of polyploidization, i.e., ancient polyploidization, tetra-, and hexaploidization, resulted in the emergence of modern allohexaploid bread wheat Triticum aestivum L. with the BBAADD genome. Polyploidization and subsequent stabilization of the polyploid genome of T. aestivum led, on one hand, to cytological diploidization and, on the other hand, to structural and functional asymmetry of its three subgenomes. In recent years, there has been a sharp increase in the data accumulation on the origin and structure of the bread wheat genomes a result of analysis of genomes and transcripomes of natural and synthetic wheats using modern mapping and sequencing methods. This review provides up-to-date information on the peculiarities of the T. aestivum genome reorganization, which affected its structure and functioning.
