🚨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🎉

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...

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!

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.

A theoretical gene regulatory network, featuring 10 genes connected randomly.

Very happy to announce the publication of our latest work by my former student Sylvain Pouzet in @journal-evo.bsky.social: "Gene network topology drives the mutational landscape of gene expression".

Avoidable false PSMC population size peaks occur across numerous studies Hilgers et al. detect and solve a common artifact in PSMC and related methods for historical population size inference. Analyses of real and simulated genomes show that ill-set default parameters fals...

‼️These #PSMC #peaks are #artifacts‼️

Seen #PSMC results like this🤔?
They are caused by ill-set parameters, #very #common, and #easy #to #solve!

Turnover of retroelements and satellite DNA drives centromere reorganization over short evolutionary timescales in Drosophila Centromeres reside in rapidly evolving, repeat-rich genomic regions, despite their essential function in chromosome segregation. This study of centromere evolution over short evolutionary timescales i...

Our new paper on the rapid evolution of centromeres in Drosophila is out! 🚀 Discover how transposable elements and satellite DNAs shape centromere dynamics and drive karyotype evolution over short timescales. @amlarracuente.bsky.social 🌟 Check it out here: journals.plos.org/plosbiology/...

Hoping to extend it more after the winter holidays, as I'm just finishing up teaching the undergrad version of class.
