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 🙌

Tethering ferredoxin-NADP+ reductase to photosystem I promotes photosynthetic cyclic electron transfer The location of the key photosynthetic enzyme FNR impacts the partitioning of photosynthetic electrons between the linear and cyclic electron transport pat

Finally! After a lot of hard work our paper on tethering FNR to PSI in Chlamy is out in @theplantcell.bsky.social

A family of NADPH/NADP+ biosensors reveals in vivo dynamics of central redox metabolism across eukaryotes - Nature Communications This article presents NAPstars, a family of genetically-encoded biosensors that enable real-time monitoring of NADP redox dynamics across species. The sensors reveal robust NADP redox regulation, cell...
