🚨Our latest work on selfish centromeres is published @currentbiology.bsky.social 🐭🧬We found that the spindle checkpoint contributes to non-Mendelian segregation! Huge congrats to our lab manager, Zaak Walton, who led the project🎉

Our new paper is out!
We observed a loss of function in mating compatibility for HD genes for the first time in basidiomycete fungi, and new evolutionary strata in the absence of sexually antagonistic selection!

Repeated loss of function at HD mating-type genes and of recombination in anther-smut fungi - Nature Communications
Basidiomycete fungi typically have two mating-type loci located on different chromosomes. Here, Lucotte et al. report the convergent loss-of-function of mating-type genes across several species of phy...

New paper out in @jxbotany.bsky.social! 🌱🌾
We found that mixing different wheat varieties can decrease belowground competition at early growth stages, especially under resource limited conditions.
