Excited to share our new preprint on BioRxiv!
A collaborative effort spanning many years and several labs to uncover what the germline chromosomes of Paramecium really look like. 🔗 www.biorxiv.org/content/10.1...
1/5
The tiny germline chromosomes of Paramecium aurelia have an exceptionally high recombination rate and are capped by a new class of Helitrons
Background. Paramecia belong to the ciliate phylum of unicellular eukaryotes characterized by nuclear dimorphism. A diploid germline micronucleus (MIC) transmits genetic information across sexual gene...

Glad to share our latest work showing that #drosophila epigenetic enzyme TET controls muscle development independently of its catalytic activity but prevents muscle aging in a catalytic-dependent manner!

How is epigenetic information inherited? We found that CDCA7 proteins are critical players in the inheritance of DNA methylation at CG sites in plants, and this is true both in the lab and in the wild. How does this work? 🧵👇
New paper! Work led by @p-bourguet.bsky.social and Frédéric Berger at the GMI of the @oeaw.bsky.social and @esasaki007.bsky.social identified how protein CDCA7 helps plants stably maintain epigenetic modifications across generations.

🚨 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) !

This is terrible news.
Clearly, a solution MUST be found!
Flybase is ESSENTIAL!!
An absolutely awful turn of events. I am heartbroken over the firing of the Flybase staff. Thanks to @claudia-lopez.bsky.social for covering this important story.
FlyBase, a Drosophila database, will lose a third of its team in early October because the Harvard grant that covered the employees’ salaries was canceled. Scientists warn that losing FlyBase could devastate fly research.
