Researchers recently investigated the evolution of grasses, one of the most economic and ecologically important plant families, by sequencing the chloroplast DNA of an early diverging grass genus, ...

Analysis: This statement is FALSE. Chloroplasts are primarily found in plants and algae. They are not present in animals, ...

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 ...

The impacts of the prokaryotic ancestry of chloroplasts extend to the occurrence of a bacterial ‘alarm’ hormone, or alarmone, in plants, which is triggered by nutrient deficiency or stress. A new ...

The chloroplast carries out photosynthesis in all multicellular plants and algae. A new study sheds light on the evolutionary origins of this organelle, potentially answering the question: what is the ...

Most chloroplast proteins are encoded in the cell nucleus, translated in the cytosol, and targeted to the organelle in a post-translational manner. Our understanding of how proteins are targeted to ...

All life on earth ultimately relies on energy from the sun, and photosynthesis is the vital link. Photosynthesis generates adenosine triphosphate (ATP), which is the universal molecular fuel in living ...

Plants use a single communication route when developing new chloroplasts Researchers in Japan and the U.K. have discovered new details of how young leaves build their first chloroplasts, the energy ...

As part of an investigation into the control of chloroplast replication the number and size of chloroplasts in mesophyll cells was examined in relation to the size of the cells. In first leaves of ...

Plant Physiology, Vol. 136, No. 4 (Dec., 2004), pp. 4048-4060 (13 pages) p-Hydroxybenzoic acid (pHBA) is the major monomer in liquid crystal polymers. In this study, the Escherichia coli ubiC gene ...

Optimal packing problems have inspired mathematicians for centuries. Biophysicists now add a layer to the question: How do chloroplasts arrange themselves optimally within cells, when the meaning of ...

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 ...
