Transcriptome Shock Invokes Disruption of Parental Expression-Conserved Genes in Tetraploid Wheat

ABSTRACT: Allopolyploidy, entailing whole genome duplication (WGD) of merged divergent genomes of different species, often instigates transcriptome shock, whereby both total gene expression level and homeolog expression partitioning can be disrupted and remodeled. Little is known about the extent to which the parental expression-conserved genes will be disrupted/remodeled by allopolyploidization, nor the evolutionary relevancy of shock-induced expression repatterning. Here, by microarray-based gene expression profiling and gene-specific cDNA-pyrosequencing, we assessed transgenerational transcriptome shock in a synthetic allotetraploid wheat (AT2) with karyotype and basic morphology mimicking those of natural tetraploid wheat, Triticum turgidum. We show that the transcriptome shock in AT2 is excepti
