A new study from the University of Helsinki reveals how plant mitochondria draw molecular oxygen away from chloroplasts, an ...

The Plant Cell, Vol. 20, No. 9 (Sep., 2008), pp. 2460-2470 (11 pages) Chloroplasts arose from a free-living cyanobacterial endosymbiont and divide by binary fission. Division involves the assembly and ...

Purdue University scientists have discovered a key mechanism that regulates how plants develop chloroplasts, essential structures responsible for the photosynthesis that sustains life on Earth by ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 103, No. 28 (Jul. 11, 2006), pp. 10817-10822 (6 pages) The biogenesis of the photosynthetic thylakoid membranes ...

Researchers identified a large novel protein complex in the inner chloroplast membrane that functions as a motor to import proteins into the chloroplast. Components of the complex evolved from a ...

A study uncovers a new role for ion transporters: they participate in gene regulation in chloroplasts. A study led by LMU plant biologist Hans-Henning Kunz uncovers a new role for ion transporters: ...

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 ...

A recent study by Chinese scientists has revealed the intricate molecular machinery driving energy exchange within chloroplasts, shedding light on a key event in the evolution of plant life. Led by ...

A research group led by Osaka University identifies a new type of protein from the red algae Cyanidioschyzon merolae associated with the import of chloroplast protein precursors and the mechanism of ...

The sun is the ultimate source of energy for virtually all organisms. Photosynthetic cells are able to use solar energy to synthesize energy-rich food molecules and to produce oxygen.

Photosynthesis is an ingenious catalytic system, allowing plants and algae to use the energy from sunlight to convert carbon dioxide into the carbohydrates they need for their cells’ metabolism—a ...
