Ferredoxin is a pivotal iron–sulphur protein that functions as an electron carrier in the photosynthetic electron transport chain. Within chloroplasts, photosystem I reduces ferredoxin, which in turn ...

A research team has revealed the molecular steps that led to the emergence of this plant-specific vacuolar transport system. Their work shows that the acquisition of this pathway was driven by the ...

Photosynthesis -- mainly carried out by plants -- is based on a remarkably efficient energy conversion process. To generate chemical energy, sunlight must first be captured and transported further.

This protein storage function is unique to plant vacuoles and does not occur in other organisms. During evolution, plants developed a dedicated mechanism to transport large quantities of proteins into ...
