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 🙌 www.biorxiv.org/cgi/content/...

Happy to share the key part of my PhD! In our latest preprint with Salma Akter, @emilyflashman.bsky.social & @beagiuntoli.bsky.social, we show that H₂S is involved in oxygen sensing in plants! How? Check it out!🌱✨ Many thanks to all the authors involved! www.biorxiv.org/content/10.1...

Hydrogen sulfide modulates plant hypoxic responses through the persulfidation of Plant Cysteine Oxidases

Hydrogen sulfide (H₂S) is a gaseous molecule historically regarded as toxic. Nevertheless, increasing evidence has brought to light important physiological roles in both animals and plants. In plants,...

Researchers develop sensors for the “charge” of biological cells

A team led by plant biotechnologist Prof Markus Schwarzländer has developed biosensors that can be used to measure the ratio of NADPH to NADP⁺ in living cells in real time for the first time.

Preprint alert, please share!! With our new study, we engineered an orthogonal hypoxia-responsive system in plants inspired by mammalian HIF protein degradation. We demonstrated that this system could control protein stability and activity, enabling modulation of Oxygen sensing outputs. Here's how:
