Long-distance transport of siRNAs with functional roles in pollen development - Nature Plants This study shows that many small RNAs in Capsella rubella pollen originate from maternal tissues. These mobile small RNAs support proper pollen development, revealing that non-cell-autonomous small RN...

New paper in @natplants.nature.com finds that #siRNAs can act as long-distance communication signals from maternal to male tissue in #Capsella with functional role in #pollen development.

AGO5 restricts virus vertical transmission in plant gametophytes The propagation of a viral infection from a host parent to its progeny is known as vertical transmission, or seed transmission in plants. It allows viral infections to rapidly spread locally via polle...

Preprint alert! It is my great pleasure to announce the first manuscript from the lab, a story that started @gmivienna.bsky.social and was mainly accomplished by the intrepid @gesahoffmann.bsky.social at @mpi-mp-potsdam.bsky.social. A brief thread with our findings

Targeted genetic manipulation and yeast-like evolutionary genomics in the green alga Auxenochlorella Auxenochlorella, green algae shaped by evolutionary forces acting on vegetative diploids, are amenable to discovery research and bioengineering via efficie

Excited to introduce Auxenochlorella as a new algal reference organism for fundamental plant science and bioengineering. A paper in two parts: a genetic toolkit for site-specific genomic manipulation, paired with the most unusual genome I’ve ever worked on

A wonderful collaboration with @ericadinatale.bsky.social, @cssmartinho.bsky.social, @rorycraig.bsky.social, and Susana Coelho! 🎉

So happy to see my first first-author paper published! 🎈
A short thread on how Ectocarpus and its TE secrets have kept me busy lately:

The Tübingen & Amsterdam crews have landed in Barcelona for #ESEB2025! Cooling off with helados before the science (and festivities) begin🍦

So excited to be at #ESEB2025 presenting poster 221 today!☀️

Check out our chromosome-level genome of Bostrychia, a red alga from the complex Ceramiales order, revealing massive genome expansion by giant Plavaka DNA transposons, the evolution of expanded gene families and UV sex chromosomes!

Transposable elements in brown algae? 🌊
Yes, they’re full of surprises ✨

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!

The art of arranging marine algae into designs, bouquets, and even sometimes intricate little scenes, was surprisingly popular in the 19th century. See an album of such pictures by a woman named Eliza A. Jordson here: https://publicdomainreview.org/collection/album-of-seaweed-pictures-1848

A wonderful summary of our recent work in @currentbiology.bsky.social . It’s an honour for it to have been written by such respected researchers in the field. Thank you @multicellgenome.bsky.social & team! 🤩

Congrats, well deserved!!

90% of you probably don’t need to read this.
But maybe some of you are curious & 10% will feel seen. Or a little less alone. This isn’t about seeking sympathy.
It’s about sharing something hard to say out loud;
partly to heal, partly in case someone needs to hear it too. (1/3)
