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.)

On mange des OGM tous les jours depuis plusieurs décennies (les plantes obtenues par mutagénèse chimique ou radiative) et ça ne pose aucun problème

“The scientific Nobels announced this week underscore that point. All three awards — granted each year in physiology or medicine, physics and chemistry — honored achievements rooted in fundamental research…Decades of inquiry paved the way for the technology, treatments and toys of tomorrow.” 🎁

Thanking the reviewers

This is the work of a tremendous PhD student, Benoit Madec, who did everything in this study (genetics, molecular biology, all the bioinformatics analyses) He defended his PhD on Monday and is now Dr Madec! I am very proud of him and all the work he has accomplished!

🚨 First pre-print from my team !! TL;DR: presence of polymorphism (sequence differences between the homologous chromosomes) can *increase* the local rate of recombination in Arabidopsis thaliana, turning cold regions of the genome hot (purple v. grey) !
