Excited to share our latest preprint. Arabidopsis thaliana has been the leading model for plant genetics - but most of what we know comes from growth chambers.
Can this model also help us understand how climate shapes plants in the wild and reveal gene functions under real environmental variability?

#SchoBozKa 2026

Exciting meeting laying ahead. Very grateful to @dromius.bsky.social for enabling me to join this years Schobozka meeting again and meet tons of amazing scientists. And look at this stunning location.

The mechanical properties of Arabidopsis thaliana roots adapt dynamically during development and to stress Brillouin microscopy reveals in vivo dynamics of mechanical properties during plant development and response to stress.

Our work now on its final version. We mapped the mechanical properties of roots at tissue and single cell levels using Brillouin microscopy and molecular rotors. Additional mutants and stress measurements from what we previously showed in the preprint are included.

The actin cytoskeleton is required to maintain plant cell division orientation against cellular geometry Actin guides plant cell division, shaping tissues in ways that defy geometric constraints.

What a treat to see the work from Camila Goldy @camilagoldy.bsky.social et al., @rdplab.bsky.social @ensdelyon.bsky.social now published 🫶

I am very excited to share my simultaneous triple staining method for monocot roots. This method is not only faster but also utilizes a smaller volume of stain than traditional methods and minimizes mechanical tissue damage.

Nikolas and I just published our insights on CLEs in plant–bio interactions. Too short to cover everything, but we hope it gets you also excited about these peptides. Thanks to @newphyt.bsky.social for the opportunity

Definitely worth listening to. David, together with the SLCU outreach community, did a really cool outreach project at the time.

Thank you to @marioncmueller.bsky.social and @huckelhovenr.bsky.social for involving me. I had fun working on the figure and learned lots as well. Congratulations to everyone 🥂

Looks amazing Darius!

A multi-plant transcriptomic atlas reveals conserved and lineage specific defense architectures in response to Botrytis cinerea Generalist pathogens pose a challenge to plant immunity by infecting diverse hosts while harboring extensive intraspecific genetic variation. Whether evolutionary distant plant lineages rely on a shar...

Ever wondered if diverse plant species respond similarly when infected by the same exact pathogen? Infect different asterids and rosids with the same Botrytis genotypes and teh short answer, quite differently.

Beautiful pictures! No bird expert but yes, the small one is a robin. We call them „Rotkehlchen“ (something like „red throat“).

Have you ever heard that women have more chances than men of getting grants or positions in academia? Of course you have, and here are my personal views on this. With the shocking revelation that no, it is NOT TRUE ! (1/n)

At the end of 2024 I did a chronological round up of all the #plantscience in @science.org that year.
So how did 2025 pan out? This year, I’m grouping papers thematically instead of chronologically so read on to find out what exciting plant science came out over the last 12 months. (1/22)

The small GTPase MaROP10 interacts with MaRIC6 to regulate rhizobial infection in Melilotus albus The symbiotic nitrogen fixation process between legume roots and rhizobia initiates at the root hairs. Rhizobia initially colonize the tip of the root hairs and induce its curling to become entrapped. However, the specific molecular mechanisms underlying root hair deformation and curling in response to rhizobial infection remain unclear. In this study, transcriptome analysis of wild-type JiMa389 and nodulation-deficient mutant jima61 of Melilotus albus, the Rho-like small GTPase MaROP10. Our results show that MaROP10 functions as an interacts with the Nod factor receptor NFR5 to regulate rhizobia-induced root hair deformation and infection thread formation during the early stages of rhizobial infection. To elucidate the mechanism of MaROP10, we further identified its downstream potential effector protein, MaRIC6, which positively regulates root hair deformation and infection thread formation. Taken together, MaROP10 likely integrates signals from the symbiotic receptor NFR5 to regulate downstream signaling pathways through its effector MaRIC6, thereby coordinating root hair deformation and infection thread development during the early stages of rhizobial infection.

‘Borrowed time’: crop pests and food losses supercharged by climate crisis Heating means pests breeding and spreading faster, warn scientists, with simplified current food system already vulnerable

The key global crops, wheat, rice and maize, are expected to see the losses to pests increase by about 46%, 19% and 31% respectively when global heating reaches 2C 👇 www.theguardian.com/global-devel...

Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.

Exciting opportunity! Can recommend working with Phil, amazing scientist with a great sense of humor as a bonus.

Check out amazing confocal images by @alexguyon.bsky.social, former member of @dromius.bsky.social lab and now postdoc in Maria Harrison’s group. He managed to image haustoria from a pathogen and arbuscules from a symbiont in the same cell! 🤩

Congratulations @steidele.bsky.social 🥳 check out Tina’s new preprint for key transcription factors being involved in barley Fusarium head blight and/or drought responses.
