What could be better than seeing a former member of your lab elected to the US National Academy of Sciences @nasonline.org? Huge congrats to Kirsten Bomblies @ethz.ch! Here are the two of us with @thanvisrikant.bsky.social , who was first a PhD student in my lab & then a postdoc with Kirsten.

An early Christmas present from our team for all of the tomato 🍅 & recombination fans: Chromosome-scale Solanum pennellii and Solanum cheesmaniae genome assemblies reveal structural variants, repeat content and recombination barriers of the tomato clade biorxiv.org/content/10.648…

Merry Xmas from the department of Chromosome Biology!

Two researchers at UC Davis have been awarded a VinFuture Prize in recognition of their work developing self-cloning crops, a breakthrough for sustainable agriculture. Read more: ucdav.is/4oJ41Hx

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) !

I feel incredibly privileged to share this study on Fanconi anaemia, based on a small but important cohort. This work describes the genetics and clinical outcomes of patients in Australia and New Zealand with a diagnosis of FA. www.sciencedirect.com/science/arti...

This is a great opportunity to start an independent group in one of the best research environments you could think of!
