Japanese researchers find a clue to the evolution of chloroplasts Their research on a single-celled eukaryote called Rapaza viridis provides a clue to unraveling the evolution of chloroplasts, according to the group.

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

Graphical abstract showing conserved action of PsbS proteins to dissipate excess light energy as heat

Light protection...

Dewa et al. show that Streptophytic PsbS proteins act as regulators of energy-dependent quenching of Photosystem II, suggesting that this conserved function dates back to the common ancestor of streptophytes prior to land plant colonization

The authors of the two papers. Carlos O. Miller standing on the left, looking down upon a couple of glass beakers. Opposite him, from the back to the front, are Malcolm H. van Saltza, Francis Shigeo Okumura, Folke K. Skoog and Frank M. Strong. Below the photo are the headers of their two papers describing kinetin, the first cytokinin: “Kinetin, a cell division factor from desoxyribonucleic acid” by Carlos O. Miller, Folke K. Skoog, Malcolm H. van Saltza and Frank M. Strong, and “Structure and synthesis of kinetin” by Carlos O. Miller, Folke K. Skoog, Francis Shigeo Okumura, Malcolm H. van Saltza and Frank M. Strong. Both published in 1955 in the Journal of the American Chemical Society.
