Breakthrough discovery in mitochondrial regulation

Researchers from Osaka University identify a system known as the "GET pathway" as essential for efficient regulation of the numbers of energy-producing mitochondria

Decoding how plants survive drought

National University of Singapore biologists have revealed how plants suppress the formation of stomata, the microscopic pores on their surface, to limit water loss during drought conditions.

Phosphorylation

Phosphorylation is the addition of a phosphate (PO43-) group to a protein or other organic molecule. Phosphorylation activates or deactivates many protein enzymes.

Protein phosphorylation in particular plays a significant role in a wide range of cellular processes. Its prominent role in biochemistry is the subject of a very large body of research (as of March 2009, the Medline database returns nearly 160,000 articles on the subject, largely on protein phosphorylation).
