🚨📢 Excited to share our back-to-back publications in @natcomms.nature.com! 🧬🌡️ In a fantastic collaboration between @casallab.bsky.social and @luciastrader.bsky.social, we’ve showed how plants "re-tune" the auxin pathway to regulate growth in response to warmth. 🌡️🌱 🧵 rdcu.be/fayYC, rdcu.be/fay0X

Ever wondered how the #cuticle, a hallmark of land plants, was established?

In our latest study, we show that the CUTIN SYNTHASE enzyme family was a key driver of this evolutionary innovation. #plantscience

Evolutionary biology: what an aquatic microorganism can tell us about our distant origins Over a period of two to three billion years, the only living beings on Earth were single-celled organisms. In what conditions did living organisms with multiple cells emerge? How did life become more ...

Choanoflagellates — our closest animal relatives — form multicellular colonies in two ways: cell division AND aggregation.

This previously unknown "mixed multicellularity" suggests our animal origins are more complex than thought.

Targeting redundant gene families: A multiplexed, tissue-specific CRISPR toolbox for Arabidopsis genetic screens Anfang et al. present a tissue-specific, multiplexed CRISPR toolbox for plants that uses paired sgRNAs and barcoded libraries to target redundant gene families. Applied to Arabidopsis nutrient transporters, it boosts editing efficiency and gene coverage, enabling spatially precise screens that uncover phenotypes hidden by functional redundancy.

"From industrial Past to Green Future" written around an ancient industry tower typical for the region together with a plant changing colours from blue to green is the motto of the German Society for Plant Sciences international Conference, the Botanik-Tagung, 2026 in Bochum Germany, that brings together plant scientists from several scientific disciplines. The logo highlights the structural change of the Ruhr area, from coal mining + heavy industries to the increasingly important issues of climate protection, sustainability + preservation of biodiversity, with plant sciences at the forefront of this transformation.

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.

Fig. 1 (shortened, full legend in paper): Simplified scheme showing biosynthesis of major plant lipids in plants. Acetyl-CoA carboxylase (ACC) and fatty acid synthase (FAS) complexes are critical enzymes in fatty acid (FA) biosynthesis. In plants, FAS is a multiprotein complex comprising various enzymes responsible for acyl transfer, carbon chain elongation, and reaction termination. The initial condensation reaction is facilitated by β-ketoacyl-ACP synthase III (KASIII), while the six subsequent condensation steps are carried out by KASI, resulting in the production of C16:0. This product is elongated to C18:0 by the action of KASII. The C18:0 is then desaturated to C18:1, a process mediated by the stearoyl-acyl carrier protein (ACP) desaturase encoded by SSI2.

🧪🌾News - How do trees know when winter has really begun?

New research from the Bhalerao group in @natcomms.nature.com shows that trees don’t just count cold hours - they also use brief warm spells early in winter.
