Transcriptome modification to the BBAA subgenomes of common wheat since allohexaploidization is largely irreversible

ABSTRACT: The three subgenomes (B, A and D) of common wheat (2n=6x=42) are largely intact, which makes extraction of the BBAA subgenomes as organismally independent genomes possible. Availability of such novel extracted tetraploid wheat (Extracted-tetra) provides a unique opportunity to study whether and to what extent the BBAA subgenomes of common wheat have been irreversibly modified, as well as its attendant biological consequences, during their evolutionary trajectory as allohexaploidy. We report here that the extracted-tetra is stable in karyotype but with severely deteriorated phenotypes. Microarray-based transcriptome analysis revealed a substantial portion of differentially expressed genes (down- or up-regulation) between extracted and natural tetraploid wheat, Triticum turgidum, which excee
