Affinity purification in Arabidopsis identified all key subunits of the outer kinetochore KMN complex. Functional analyses revealed a striking conservation of its composition and organisation across kingdoms, underscoring its deep evolutionary origin.

www.nature.com/articles/s42... Latest from the lab. The conclusion is in the title! Basically, we found that the KMN complex (outer kinetochore) is fully conserved between plants and fungi/animals, showing deep origin. (reminder, you are closer to a mushroom than a mushroom is to a plant.)
