The identification of the very conserved CTF18, SGO2 and SPF2 as suppressors of centromere-proximal crossovers highlights the importance of cohesin turnover in this process and opens up new possibilities for plant breeding. rdcu.be/fvHfe
The deSUMOylase SPF2 and the cohesin regulators SGO2 and CTF18 suppress crossovers near centromeresNature Plants - Gamboa et al. identified three proteins that restrict meiotic crossovers near centromeres. This finding suggests that cohesion regulation plays a role in this suppression and...rdcu.beand guess what, some did! The cohesion regulators CTF18 and SGO2, and the deSUMOylase SPF2 actively limit centromere proximal crossover. Their mutation allows both the formation of crossover where they were completely absent in the wild-type, and enhance their frequency where they were rare!

We recently described some mutants with modified kinetochre orientation at meiosis, associated with reduced cohesins, and likely modified chromatin looping close to centromeres. www.cell.com/current-biol...
Cohesin and its regulation promote monopolar kinetochore orientation at meiosis I in ArabidopsisSingh et al. used a forward genetic screen in Arabidopsis to identify ten proteins
that promote monopolar kinetochore orientation during meiosis I. Cohesin subunits
and cohesin regulators, CENP-C, and...www.cell.com

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.
