Bacteria are amazing! The abundant Dps protein binds and protects DNA in stationary-phase cells with minimal effect on chromosome accessibility, dynamics, and organization. Now in NAR doi.org/10.1093/nar/...; I'm really proud of our multidisciplinary team led by Lauren, Lindsay, and Xiaofeng, et al.

🎉🥳👏Congratulations to Olivier and to the consortium. Excellent results will come to light soon in the #GenomeBiologyI2BC Department.
I am very proud to announce that our team has received an ERC synergy grant from @erc.europa.eu. A wonderful recognition of a truly collaborative effort with friends (Julius Lukes, Leos Valasek and Mark Osborn). Excited to begin this journey at @i2bcparissaclay.bsky.social @cnrs.fr
The newly announced ERC Synergy Grant includes research on:

✴️ genetic drug design
✴️ the Big Bang's first microseconds
✴️ crowd movement
✴️ nature-society interactions

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) !
