@tobybarilbio.bsky.social and I are very excited to release MycoMobilome! A very extensive effort to discover, QC and annotate TEs across the fungal kingdom.

👉 Ready-to-use for your own genome with a simple tutorial!
👉 Metadata about TEs discovered in your genome!
👉 Contribute and get recognition!

I'm thrilled to announce that I’m opening my own research team in the Department of Genome Biology at I2BC @i2bcparissaclay.bsky.social ! #ATIP-Avenir
Very excited to start this new adventure! www.i2bc.paris-saclay.fr/equipe-intra...

These stinkbugs coat their eggs in fungi to protect them from parasitic wasps An unusual relationship could shed light on how insects choose their partners

Fungal #GenomeSize variation is largely driven by TEs & lineage-specific genome defenses. @tbadet.bsky.social & @danielcroll.bsky.social show that presence/absence of RIP mutation systems influences #genome architecture, identifying a likely novel defense mechanism @plosbiology.org 🧪 plos.io/4hcC5tx

BIG ANNOUNCEMENT📣: I haven’t been this excited to be part of something new in 15 years… Thrilled to reveal the passion project I’ve been working on for the past year and a half!🙀🥳 (thread 👇)

People arm in arm while drinking coffee and holding papers, with text: Why scientists should take more coffee breaks.

Here's a reminder on #InternationalCoffeeDay: It's OK to take a (coffee) break. ☕

"It’s ... helpful to have a venue to share the day-to-day ups and downs of life as a grad student," a #PhD student wrote in this 2019 #ScienceWorkingLife. https://scim.ag/4nvLTBb

The recombination frequency (cM/Mb) along chromosome 4 of A. thaliana (female meiosis). In full hybrids (grey), where polymorphism is distributed all along chromosomes, most crossovers occur in the regions surrounding the Centromere (Cen), and very few at chromosome ends (Tel: telomeres). In lines where polymorphism is restricted to chromosome ends (purple), the local recombination rate increases drastically, at the expense of the non-polymorphic regions (yellow).

🚨 First pre-print from my team !!

TL;DR: presence of polymorphism (sequence differences between the homologous chromosomes) can *increase* the local rate of recombination in Arabidopsis thaliana, turning cold regions of the genome hot (purple v. grey) !
