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 ...

Plants of different species can swap chloroplasts, the little cellular factories that capture energy from sunlight, when stems graft together. The surprising discovery may explain why evolutionary ...

The ability of plants to convert sunlight into food is an enviable superpower. Now, researchers have shown they can get animal cells to do the same thing. Photosynthesis in plants and algae is ...

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 ...

Cyanobacteria are among the oldest life forms, and appear to be the forerunners of green chloroplasts in plant cells. They do not possess a true cell nucleus, but their genetic substance is made up of ...

A new discovery of a type of autophagy could lead to new methods for controlling aging in plants, report scientists. Researchers at Tohoku University have identified a previously uncharacterized type ...

Energy production in nature is the responsibility of chloroplasts and mitochondria and is crucial for fabricating sustainable, synthetic cells in the lab. Mitochondria are not only "the powerhouses of ...

An ultrastructural approach was used to study the effects of light and dark starvation on chloroplasts symbiotic in the mollusc Elysia viridis. Starvation for 27 days in a 16 h light/8 h dark ...

In a world first that challenges what we thought we knew about biology, scientists have successfully engineered animal cells that can photosynthesize. The breakthrough promises to revolutionize ...

Researchers in Japan have achieved a milestone in cellular biology by embedding chloroplasts from algae into hamster cells, creating photosynthetic animal cells that survive and continue ...

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 ...

For more than a billion years, plants have had an internal dialogue, and we are just beginning to learn the words. The unusual conversation occurs between two compartments within plant cells—the ...
