After 12 years… In 2014, a wild idea was born: to follow female meiosis in Arabidopsis in real time. After many trials (including experiments with quirky mutants where female organs developed inside out, and a few other unconventional ideas), we switched gears to image the male side.

Preprint Alert! 🚨🧬 Not one, but two preprints! Meiotic orientation of kinetochore at meiosis is inforced by...[see below] www.biorxiv.org/content/10.1... and Unlocking meiotic crossovers next to plant centromere www.biorxiv.org/content/10.1... #meiosis4ever #everythingisconnected a thread👇

1/5 ✨Proud✨ to see our review with Katie Peichel as featured content in Trends_Ecol_Evo, with my beloved alpine lineages of Arabidopsis arenosa on the cover. Hope that you find it interesting! doi.org/10.1016/j.tree.2023.11.007

Check out the Views & News piece that Joiselle Fernandes and I wrote for @nature.com on the recent work from @amarques.bsky.social and colleagues about one of the most bizarre ways to do meiosis rdcu.be/euabu. Explained for non-experts!

"Treasure your exceptions":

Our latest work is out in @pnas.org! We have quantified and modeled the dynamics of early meiosis events, which can get really messy in polyploids (doubled number of chromosomes, double the trouble), but can also get fixed through adaptive evolution 🧵1/8. www.pnas.org/doi/10.1073/...

A beautiful reminder that the classification of allo- and autopolyploid is indeed more complex than whether they have hybrid or non-hybrid origin. Also, a beautiful reminder of how genome doubling can be a driver of agronomy-relevant innovations. Great paper! www.nature.com/articles/s41...
