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 ...

Plants fix 258 billion tons of CO 2 in their chloroplasts through photosynthesis every year. For these cell organelles to work properly, they require certain minerals—particularly ions of the metals ...

When plant cells are infected with pathogens, networks of tiny tubes called stromules grow from the chloroplasts to the cell's nucleus and trigger programmed cell death and innate immune responses.

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 ...

The signal recognition particle (SRP) has evolved in chloroplasts to include new components, new ways of recognizing targeting substrates and new capabilities that prevent aggregation of ...
