We’re excited to share a new CRISPR-Cas12 genome editing system, highly efficient across multiple brown algae species!

Brown algae transformation has been challenging despite many thoughtful approaches over the years.

We hope this one is kelpful 🌿😅

A roadmap to developing unified streptophyte algal model systems Carrillo-Carrasco and colleagues highlight the importance of the establishment of streptophyte algal model systems and the community efforts towards this goal.

We've tried to gather and unite the streptophyte algae community all around the world to join forces and develop tools and methods for these critters. Learn more about it on @currentbiology.bsky.social!
With @jandevries.bsky.social, @dolfweijers.bsky.social, and (many) others!

Conservation of chromatin states and their association with transcription factors in land plants The complexity of varied modifications of chromatin composition is integrated in archetypal combinations called chromatin states that predict the local potential for transcription. The degree of conse...

New Pre-print! A long-standing question for transcription factor biology is how their chromatin context dependency works in plants. In this collaboration with Fred Berger lab, we present some new ideas not only in Arabidopsis but also in Marchantia. www.biorxiv.org/content/10.1...

Conservation and divergence of UVR8-COP1/SPA-HY5 signaling in UV-B responses of Marchantia polymorpha Ultraviolet-B radiation (UV-B) poses a major challenge to all forms of plant life. The liverwort Marchantia polymorpha (Marchantia) serves as a key model organism to study signaling pathways and to in...

New preprint! 😁 We uncover how early land plants evolved UV-B tolerance by dissecting the UVR8 pathway in Marchantia polymorpha. Conserved yet rewired—evolutionary plasticity revealed. 👉 www.biorxiv.org/content/10.1... #PlantScience #UVB #Evolution

Really cool start of a week of conference yesterday at #OMGN2025. I learned so much about oomycetes and got to present our some of our work studying its interaction with Marchantia. Looking forward a free morning in Cologne and to #2025ISMPMI starting later today!

Franklin W. Stahl, 95, Dies; Helped Create a ‘Beautiful’ DNA Experiment

As an undergraduate who loved physical chemistry and was just starting biology, I thought the Meselson-Stahl experiment was the coolest thing ever. It was so simple in its application of physical theory and experiment to prove a biological truth that it was perfect. www.nytimes.com/2025/07/07/s...

Some bryophytes from 🇨🇱! 🤩

Most plant-friendly fungi are a mystery to scientists Most fungi that partner with plants are known only from trace DNA sequences left in soil.

Tom Parker @hutton.ac.uk and I wrote for @theconversation.com discussing why it’s important to find out what’s out there in terms of mycorrhizal fungi following a the revent review in @currentbiology.bsky.social by the @spun.earth team. Read it here: theconversation.com/most-plant-f...

regrettably, it looks really good

Spent last week at the microscope 🔬✨, and seeing arbuscular mycorrhizal fungi up close for the first time—hyphae, arbuscules, vesicles—was absolutely mind-blowing. Small but mighty partners of plant roots 🌿. Sharing a few of my favourite shots.
