(Submitter supplied) Centromeres typically contain repeat sequences, but centromere function does not necessarily depend on these sequences. In aneuploid wheat (Triticum aestivum) and wheat distant hybridization offspring, we found functional centromeres with dramatic changes to centromeric retrotransposon of wheat (CRW) sequences. CRW sequences were greatly reduced in the ditelosomic lines 1BS, 5DS, 5DL, and a wheat-Thinopyrum elongatum addition line. more...

(Submitter supplied) To investigate genome-wide maternal and paternal contributions to polyploid grain development, we produced and analyzed transcriptomes from zygote to mature stage embryos as well as two endosperm stages derived from reciprocal crosses between tetraploid and hexaploid wheats.

(Submitter supplied) Common wheat (T. aestivum) converged three subgenomes adapted to different environments. The combinatorial interaction between transcription factors (TFs) and regulatory elements (REs) defines a regulatory circuit that underlies subgenome convergence and divergence. Compared to the relatively conserved gene composition across subgenomes, the intergenic regions with abundant REs is drastically diversified by almost complete TE turnovers, raising major questions regarding how subgenome convergent and divergent regulation is encoded in the highly diversified intergenic regions, and the impact of TE evolution on regulatory conservation and innovation. more...
