Marcus kinetics control singlet and triplet oxygen evolving from superoxide - Nature

The release of triplet or singlet oxygen is governed by individual Marcus normal and inverted region behaviour.

“Biological systems know how to defend themselves from singlet oxygen. Whether we are doing basic chemistry or developing batteries, we must take inspiration from biology,” says Soumyadip Mondal, the study’s first author.

Researchers from the group of Stefan Freunberger at ISTA show that the pH inside mitochondria, the ‘powerhouse of the cell,’ might hold the answer.

While some reactive oxygen species (ROS) play essential roles in cell signaling, the particularly harmful singlet oxygen wreaks havoc inside cells and batteries. But what exactly causes this ‘bad’ oxygen to evolve, and how can it be tuned?

📢 New paper: a combination of a new isotope labelling with solution-NMR, allowing to assign methyl groups even in large proteins -- we've tested it with our favourite ~130 kDa enzyme and a 70 kDa receptor.

Think of it like a snowball rolling down a hill, growing larger as it picks up more snow. Similarly, auxin enhances its own transport along the root’s lower side, guided by gravity to ensure the root delves deeper into the soil.

Institute of Science and Technology Austria (ISTA) @istaresearch.bsky.social · 6d

The new study, led by Postdoc Lesia Rodriguez and PhD student Lukas Fiedler, provides new insight into these events. They found that auxin accumulation activates a cell-surface module that stabilizes auxin transport, creating a positive feedback loop.

When roots lie horizontally, gravity pulls amyloplasts to the lower side of the columella cells, which triggers a signaling cascade and accumulates the hormone auxin at the lower root side, prompting the root to bend downward.

At the heart of gravity sensing are columella cells at the root tip. These contain amyloplasts, special compartments packed with heavy starch particles.

The video shows positive gravitropism—roots growing downward with the Earth’s gravitational pull—and negative gravitropism—shoots growing upward against gravity.

This growth guidance is called “gravitropism” and was first proposed to involve the plant hormone auxin in 1927. Even though almost 100 years have passed, many molecular mysteries of gravitropism remain unsolved.
