So happy this is out as a preprint (for) now. Since measuring ATP is tricky, we used ATP biosensors in collab with @schwarzlanderlab.bsky.social to show that in chloroplasts without PGR5, NPQ and pmf are diminished, yet ATP levels unchanged. Balancing ATP/NADPH must be achieved by different means.
Our new preprint 🚨🌱☀️on flourescent biosensing of ATP levels in chloroplasts in vivo shows disequilibrium between proton motive force and ATP levels. We show PGR5 dependent cyclic electron transfer does not augment ATP/NADPH ratios @gustaf23.bsky.social 🙌

Today, Germany remembers the November pogroms of 1938.
87 years ago, Jews were targeted in a wave of orchestrated violence in Germany. Jewish shops and synagogues were destroyed. Many Jews were murdered.
These acts of terror paved the way for the Holocaust.

His vision to establish one of the first journals dedicated to Global Change over 30 years ago was truly ahead of its time. Through GCB, researchers have demonstrated that biology and ecosystems are not simply victims of global change..

Hi authors! Please remember to file a claim!
AI advocates have warned that if every author in the class action filed a claim, it would "financially ruin" the entire industry.
Authors celebrate “historic” settlement coming soon in Anthropic class action

As the world warms, plants in natural ecosystems and agricultural settings find ways to respond to the heat.
In a new special issue of Science, researchers examine how heat affects plants at multiple scales, from the molecular level to the biosphere. scim.ag/44cSw3Z
