The theory of pivotal-differential evolution states that one genome of polyploid wheats remains stable (i.e., pivotal) during evolution, while the other genome or genomes may become modified (i.e., differential). A proposed mechanism for apparent modification of the differential genome is that different polyploid species with only one genome in common may exchange genetic material. An alternative explanation is that, the differential genomes are variable due to variability imparted by diploid progenitors. In this study, we analyzed a set of sympatric and allopatric accessions of tetraploid wheats of genomic constitution UM and UC. The U genome of these species is from Triticum umbellulatum. and is considered to be the pivotal genome. The M ...
