Plants must carefully strike a balance between harvesting sunlight to fuel photosynthesis and protecting themselves from light damage. Part of this balancing act is performed by antenna proteins that ...

For decades, science has understood the basics of photosynthesis, the process by which plants turn sunlight into food.

In addition to conspicuous large mesophyll chloroplasts, where most photosynthesis occurs, small epidermal chloroplasts have also been observed in plant leaves. However, the functional significance of ...

Scientists have identified three different signals that indicate damage to chloroplasts -- the photosynthetic factories of plant cells that give plants their green color -- but little is known about ...

By utilizing bacterial enzymes that cleave heme molecules at different sites, Research teams of the University of Tokyo and ...

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

Experimental seedlings in the laboratory. UC Davis plant biologists have discovered how chloroplasts, responsible for photosynthesis in green plants, also play a key role in plant immunity to ...

Under cold conditions, not only the mother plant but also the father plant can pass on its chloroplasts to the offspring. Scientists at the Max Planck Institute of Molecular Plant Physiology in ...

Chloroplasts may seem like docile farmers of light. But inside these microscopic plant and algal cell structures lurks the spirit of a warrior. When a pathogen attacks a plant, chloroplasts stop ...

A group of Japanese researchers has confirmed that Rapaza viridis, a single-celled eukaryote, sends proteins derived from its own genes to chloroplasts it takes from green algae to have them conduct ...

Studying sea slugs in the group Sacoglossa can mean being on the receiving end of some very imaginative emails. Sidney K. Pierce, of the University of South Florida, retired a few years ago. “But to ...
