How do new centromeres evolve while staying compatible with the division machinery?
Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore.

We mourn the passing of our Editor-in-Chief Steve Long.
His vision to establish one of the first journals dedicated to Global Change over 30 years ago was truly ahead of its time. Through GCB, researchers have demonstrated that biology and ecosystems are not simply victims of global change..

We’re excited to share our new work on how plants restore cytonuclear balance after whole-genome duplication. Using Arabidopsis auto- and allopolyploids, we uncover distinct, organelle-specific strategies in chloroplasts and mitochondria across generations.

Restoring cytonuclear harmony: Distinct strategies in Arabidopsis auto‐ and allopolyploids
Whole-genome duplication (WGD) disrupts cytonuclear balance by doubling nuclear content, requiring compensatory responses from organelles. In Arabidopsis auto- and allopolyploids, we found dynamic, o...
