TL;DR: An in-depth investigation on transgenerational chromosomal variation in resynthesized allohexaploid wheats that are identical in genome constitution to common wheat finds that whole-chromosome aneuploidy occurred ubiquitously in early generations of wheat allo hexaploids although at highly variable frequencies (20–100%).

TL;DR: The results suggest that the open chromatin signature-based enhancer prediction system developed in Arabidopsis may serve as a universal system for enhancer identification in plants.

TL;DR: It is hypothesized that in cold-stored tubers, the bivalent H3K4me3-H3K27me3 mark represents a distinct chromatin environment with greater accessibility, which may facilitate the access of regulatory proteins required for gene upregulation or downregulation in response to cold stress.

TL;DR: The results suggest that rampant genetic instability associated with nascent allohexaploidization in wheat likely represents incidental and anomalous phenomena that are confined to by-product individuals inconsequential to the establishment of the newly formed plants toward speciation of T. aestivum.

TL;DR: Microarray-based genome-wide gene expression analysis on two newly synthesized allohexaploid wheat lines with chromosomal stability and a genome constitution analogous to that of the present-day common wheat shows that two patterns of global alteration in gene expression are conditioned by allo hexaploidsization in wheat.
