Researchers Discover Switching Protein Protects Plants from Too Much SunlightApril 28, 2021
A switching protein plays a role in protecting plants from too much sunlight, but how it exactly happens was not fully understood. Now, researchers from the Leiden Institute of Chemistry and VU Amsterdam led by chemist Anjali Pandit have discovered how the switching effect of the PsbS protein works.
The team discovered that the PsbS protein changes its shape when there is a surplus of sunlight. Using advanced nuclear magnetic resonance (NMR) and infrared laser techniques, they managed to show where essential structural changes take place in the protein. The results of their work are published in Nature Communications.
Pandit says that it is important to learn more about the mechanisms behind photosynthesis. "By tinkering with photosynthesis, for example by fine-tuning this protection mechanism against damage, we can improve crops." Earlier research shows that tobacco plants with increased PsbS production yield 15 percent more biomass. The next step is to find out how PsbS transmits a warning signal in the plant and how this leads to the adjustment of the photosynthesis reaction.
