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...

Photorespiration is linked to DNA methylation by formate as a one-carbon source - Nature Plants This study reveals that Arabidopsis reassimilates formate produced during photorespiration via the cytosolic folate cycle to fuel DNA methylation, forming a metabolic–epigenetic bridge that links elev...

Not all “wasted” carbon is lost: formate released during photorespiration can be reused to support DNA methylation. Our work reveals a metabolic link between CO₂ levels and epigenetic regulation in Arabidopsis.

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?

Plants use cell-surface and intracellular receptors that collaborate to detect pathogens🦠. We discovered that a key #ubiquitin recognition event recruits both receptor types into an unexpected dual receptor complex that boost the translation of defence proteins and establishes robust #PlantImmunity👇🏾
