Someone got Cas9-Turbo to work. It's like basically Y1H but with proteomics. It however requires transgenic plant expressing Cas9-Turbo and gRNAs, which is still cumbersome for many plants that are not Arabidopsis. #PlantSciences

This week in Olomouc, we came together for an informal meeting on Kinetochore and Centromere. We shared ideas, did science, and strengthened collaborations. Many thanks to all the researchers who joined us. It was a great way to close the year by sharing knowledge, projects, and future perspectives.

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. 👉 doi.org/10.1038/s41586-025-09779-1
