🚀 Great to see @eurobioimaging.bsky.social highlight the innovative #EnderScope, a low-cost, open-source microscopy system expanding access to imaging! 🔬👏 Kudos to Jérôme Mutterer (IBMP microscopy platform). ▶️ www.eurobioimaging.eu/news/innovat...
Very excited to present our new project #BYGENEX, an @ERC_Research Advanced Grant! During the next five years we will be studying the genetic mechanisms that govern the phagocytosis of bacteria by protists @icmcsic.bsky.social
New article on #protist global distributions combining the #Mixoplankton and #metaPR2 databases with revised functional annotations led by @lusantof.bsky.social, Michaela E. Larsson, and Suzana Leles with Aditee Mitra and Emile Faure. Now available on Ocean Microbiology rdcu.be/fanlx

Docker containers are now available for the three PR2 applications: - pr2-database: reférence database - pr2-primers: primer database and analysis - metapr2: metabarcode database and visualization. This by far the easiest way to use these databases on your computer. hub.docker.com/repositories...
For those of you who are using metaPR2 extensively, a good alternative to installing the R package which can cause trouble because of dependencies, you can try the newly available docker container: hub.docker.com/repository/d...
Using Docker for work? We recommend signing in with your work email address.

Fantastic work done with a very large number of RCC strains.
🚨Our collaboration with @centriolelab.bsky.social & @gautamdey.bsky.social is out today in @cp-cell.bsky.social We show that #Expansion #Microscopy is a broad-spectrum modality for Euks, enabling 3D phenotypic maps rooted to phylogeny. #ProtistsOnSky #SciComm #SciSky www.cell.com/cell/fulltex...
Another piece of fascinating work done with RCC strains.
Exciting day for the lab: our 1rst paper is officially out in @currentbiology.bsky.social 🥳 Wonderful collaboration wt @gautamdey.bsky.social showing how Cryo-ExM achieves consistent immunostaining in diverse diatoms, from the lab and the natural environment 1/n #ProtistsOnSky tinyurl.com/2zxaund7
We have added more than 900 new GenBank sequences to the RCC database that are linked to the web page of the corresponding strains.
New version of PR2 that now includes the eKOI coi database recently published.
Version 5.1.1 of the PR2 database has been released. The major novelty is the inclusion of the recently published eKOI database (coi gene- doi.org/10.1093/data...) in the web interface. The 18S rRNA database is not changed so you can use 5.1.0 or 5.1.1 for metabarcode annotations
PR2 primers version 2.1.0 has been released. This does not include any new primer, but now the database uses the latest version of PR2 (5.1.1) to perform in silico analyses. Access here: app.pr2-primers.org
