      • A molecular mechanism for Wnt ligand-specific signaling

        The Wnt decoding capacities of vertebrate cells and the functional diversification of Wnt family members are elucidated.

      • The transcriptional landscape of polyploid wheat

        Expression profiling of homoeologs (pairs of genes united by polyploidy) across tissues reveals expression asymmetry along wheat chromosomes.

      • Shifting the limits in wheat research and breeding using a fully annotated reference genome

        The 21 annotated chromosomes of bread wheat provide a foundation for innovation in research and breeding.

COVER Spikes of bread wheat (Triticum aestivum), a hybrid of three distinct genomes. Scientists have recently completed sequencing of a high-quality reference wheat genome and identified how the three ancestral genomes work at a genetic level to form a staple of human nutrition.
