What to know about Genomics

An international research team led by the IPK Leibniz Institute has published a high-quality reference genome sequence for rye in Nature Communications. The study provides a more complete mapping of centromeres and identifies genetic diversity in the 1RS chromosome arm that could be utilized to improve wheat breeding.

What happened

Rye reference genome uncovers diversity that could strengthen wheat breeding Robert Egan Senior Editor Rye is not only a hardy and high-yielding crop, but also possesses a valuable gene pool for wheat breeding.

Why it matters

An international research team led by the IPK Leibniz Institute has significantly improved the foundations for research and breeding by publishing a high-quality reference genome sequence.

Common ground

For the first time, the sequence includes the complete centromeres of all seven chromosome pairs.
