<3 reproductive (in)compatibilities. Currently postdoc-ing on self-incompatibility in Brassicacae, in Lille. Past loves: Wolbachia in mosquitoes, fungi. 🌈🇵🇸

We show that:
- recombination rather than mutation is at the ❤️ of CI patterns diversity
- most toxins are truncated and play no role in CI
- there is polymorphism outside of toxin-antitoxin binding regions which likely results from horizontal gene transfer AND influences CI patterns.

I forgot to mention it here, my last PhD chapter (Wolbachia in Culex) is now published in @molbioevol.bsky.social
I think it's a cool study, give it a try 😌
Includes: wPip cid repertoires from all around the world (Nanopore seq. of PCR products), crosses, stability + toxicity tests in cell lines.
Recombination, Truncation and Horizontal Transfer Shape the Diversity of Wolbachia-induced Cytoplasmic Incompatibility Patterns
Abstract. Wolbachia are endosymbiotic bacteria inducing various reproductive manipulations of which cytoplasmic incompatibility is the most common. Cytopla

A common type of ant in Europe breaks a fundamental rule in biology: its queens can produce male offspring that are a whole different species

‘Almost unimaginable’: these ants are different species but share a mother
Ant queens of one species clone ants of another to create hybrid workers that do their bidding.

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...
