I've got something to "TORC" about! 😅 After 4 years building this project at @biologyunifreiburg.bsky.social, I'm so excited to share that my first independent preprint is now online! ✨ I hope you like it: doi.org/10.64898/202... A short thread... 🧵 #PlantSci #PlantScience

1/7 New preprint: we found that Chlamydomonas carries a giant and unexpectedly elaborate chloroplast RNA polymerase with 12 previously unknown subunits, overturning the idea that the complexity of this organellar enzyme emerged during plant terrestrialization! www.biorxiv.org/content/10.6...

Super exciting work after many conference talks finally seeing the light. Congrats and kudos to all authors: www.biorxiv.org/content/10.6...
