Professor Gabriela S. Schlau-Cohen (center) and graduate students Raymundo Moya (left) and Wei Jia Chen worked with collaborators at the University of Verona, Italy, to develop a new understanding of the mechanisms by which plants reject excess energy they absorb from sunlight so it doesn’t harm key proteins. The insights gained could one day lead to critically needed increases in yields of biomass and crops. Photo: Stuart Darsch

Understanding how plants use sunlight

The sun is the main source of energy for almost every living thing on Earth. It gives a plant the light energy it needs...
Scientists capture photosynthesis in unprecedented detail

Scientists capture photosynthesis in unprecedented detail

Scientists at the Lawrence Berkeley National Laboratory have successfully captured a picture of steps in the reaction mechanisms in photosynthesis. To capture the image, scientists used SLAC’s...
Redox regulation in plants to control photosynthetic activity Reduction/oxidation reactions in plants that control the activity of photosynthetic proteins when light is present (unshaded) and when it is absent (shaded). Unlike the well-known reactions that occur in the light, the mechanism of regulation in the dark was poorly understood. This study demonstrates that energy is funneled from the proteins to TrxL2 to 2CP and finally to hydrogen peroxide, keeping photosynthesis on standby until light is available again.

How do the plants relax photosynthesis at night?

Photosynthesis is a process used by plants in which energy from sunlight is used to convert carbon dioxide and water into molecules needed for...

When the seed becomes plant, it has 48 hours to survive

Germination is the process of seeds developing into new plants. First, environmental conditions must trigger the seed to grow. Usually, this is determined by...
How plants use carbon affects their response to climate change

How plants use carbon affects their response to climate change

The photosynthesis process is well known. Plants inhale carbon dioxide and exhale oxygen. During inhalation, plants use some of the carbon for respiration whereas some...
After five days, rice plants with the extra phosphorylase peptide removed (right) are nearly double the size of normal rice plants (left).

Eradicating plant enzyme could result in faster growth, more food

A new study by three WSU researchers discovered that how phosphorylase, a chemical that plants and creatures both have, works with photosynthesis. Phosphorylase has been studied...

New Study Shines Light on Photosynthesis Process

A photosynthesis is an essential process for humans and plants as well. The photosynthesis process is used by plants and other organisms to convert...
