An unconventional Rubisco small subunit underpins the CO2-concentrating organelle in land plants In many algae, photosynthesis is boosted by biophysical CO2-concentrating mechanisms, which pack the CO2-fixing enzyme Rubisco into liquid-like organelles called pyrenoids. Engineering C3 crops with a...

Our work on #hornwort #pyrenoids is finally out in @science.org! 🎉 We uncovered how hornworts pack their Rubisco into pyrenoids and successfully recreated them in Arabidopsis. A key step toward engineering more efficient photosynthesis in crops @btiscience.bsky.social www.science.org/doi/10.1126/...

Latest preprint from the lab!

Did you ver wonder whether the symbiotic function of DELLA is something ancestral in land plants ☘️?

@katharinamel1.bsky.social found out for you! 🔽

New paper from the lab. Important insights into the compartmentalisation of terpene biosynthesis in Marchantia oil body cells. #PlantScience #SynBio www.nature.com/articles/s42...

Congrats Katharina, nice work! 💪

1/ ✨ New preprint alert ✨

It is my pleasure to share:
"Stepwise evolution of the developmental and symbiotic functions of DELLA in land plants"

Here we investigated the role of the single GRAS transcription factor DELLA in #MyMarchantia

Graphical abstract that visually shows the workflow with photos of each step. The steps show the plant growth and bacterial growth steps: 1. Preparation of rhizobia and seedlings for spot inoculation. 2. Root zone marking and precise bacterial droplet application. 3. Incubation in EdU medium to label DNA replication. 4. Sample fixation and replicated DNA labelling 5. Tissue clearing and cell wall staining

Powerful new protocol from @kathschiessl.bsky.social's lab to trigger & visualise earliest stages of symbiotic root nodule formation in Medicago truncatula — no genetic reporters needed means broad species application!

Really happy to see this one out: www.sciencedirect.com/science/arti... Alibek's drive & great coll w/ friends @gekaragoz.bsky.social & E. Hallacli resulted in a cool story that starts with our beloved #Marchantia and ends with iPSC-derived neurons 🤩🤪 A short 🧵

#SchoBozKa 2026

It’s that time of year! #SchoBozKa in Downing College, Cambridge 🇬🇧

Running strong since 2017–Annual lab meeting of the teams of Sebastian Schornack, Lida Derevnina, Phil Carella, Jiorgos Kourelis and Sophien Kamoun.

This year’s guest is Steven Spoel, University of Edinburgh

📣 Our latest story just dropped on bioRxiv:: A structurally unique effector shared between Verticillium dahliae and Fusarium oxysporum is involved in cotton defoliation and virulence on other hosts www.biorxiv.org/content/10.6... 🧵

Finishing the week with some beautiful Marchantia - colonized by R. irregularis ❤️ #symbiosisrocks ☺️

Big news from our lab: we can now stably edit the genome of a parasitic plant! Transgene-free, genome-edited P. japonicum in one generation! This will transform how we study #parasiticplants and other hard-to-transform plants.

Multi-omics analyses of mutants for Marchantia polymorpha FERONIA and MARIS reveal a link between cell wall integrity and abscisic acid responses Abstract. At the core of cell wall integrity (CWI) mechanisms that enable plant cells to coordinate their growth with their cell wall status, lies the tran

📣 Our lab is seeking a postdoc to study mutation mechanisms in fungi using cutting-edge sequencing + computational biology. No active posting/grant right now, but we’re excited to host postdoc fellowship applicants in our comparative immunology team.
Interested? Reach out DM email. krasilevalab.org

Please share!
My group at @zmbp-tuebingen.bsky.social is offering a post-doctoral position (4 years). We look for a structural biologist with experience in Cryo-EM/Cryo-ET to investigate the mechanisms of host invasion by pathogenic fungi. Deadline February 28th!

We’re looking for a postdoc to investigate Pseudomonas viridiflava virulence across diverse plant lineages. The 3yr position will combine plant and microbial molecular biology to understand core processes of infection - email for more info & apply online @ www.jic.ac.uk/vacancies/po...

One of the most rarest and enigmatic bryophytes is now in the lab: Takakia lepidozioides. Thanks to the IMSC and Reski lab at Freiburg for maintaining them. #PlantScience

Thanks! 😊 all enabled by the very fun toys (or should I say facilities?) from @dromius.bsky.social at @slcuplants.bsky.social

Having fun with the microscope lately. Here’s one of my favourite artsy and slightly psychedelic shots of #Marchantia chloroplasts and a fluorescent membrane reporter. (z-stack maximum projection)

The 4th annual non-seed plant flash talk showcase extravaganza didn’t disappoint #nonseedUK25 🌱

Fantastic closing keynote by @rensingstefan.bsky.social. Thanks for joining us and telling us about all of the great @watertoland.bsky.social outputs 👍

Thanks to everyone who came along to the #nonseedUK25 meeting. Another fantastic day of non-seed science. Thanks to @philcarella.bsky.social and Kayla Robinson for looking after us all so well 👍

Non-seed science is accelerating forwards at a truly impressive rate. Thanks to @philcarella.bsky.social and Kayla Robinson for an awesome #nonseedUK25 meeting, and to @justingoodrich.bsky.social and @sandyheth.bsky.social for agreeing to organise #nonseedUK26 in Edinburgh - looking forward to it 👍
