Stanford, CA—Sugars are an essential source of energy for microrganisms, animals, and humans. They are produced by plants, which convert energy from sunlight into chemical energy in the form of sugars through photosynthesis. These sugars are taken up into cells, no matter whether these are bacteria, yeast, human cells, or plant cells, by proteins that create sugar-specific pores in the membrane that surrounds a cell. These transport...

Stanford, CA—Everyone’s heard of the birds and the bees. But that old expression leaves out the flowers that are being fertilized. The fertilization process for flowering plants is particularly complex and requires extensive communication between the male and female reproductive cells. New research from an international team from Stanford, Regensburg, Heidelberg, and Munich, and including Carnegie’s Wolf Frommer, David...

Stanford, CA—Soil is a microscopic maze of nooks and crannies that hosts a wide array of life. Plants explore this environment by developing a complex branched network of roots that tap into scarce resources such as water and nutrients. How roots sense which regions of soil contain water and what effect this moisture has on the architecture of the root system has been unclear. New research from a team led by Carnegie’s José...

Stanford, CA— A team of researchers studying a flowering plant has zeroed in on the way cells manage external signals about prevailing conditions, a capability that is essential for cells to survive in a fluctuating environment. Researchers at UC Berkeley, the Plant Gene Expression Center, UC San Francisco, and the Carnegie Institution for Science identified a novel mechanism by which the strength of such an external signal is reduced, or...

Stanford, CA—All living cells are held together by membranes, which provide a barrier to the transport of nutrients. They are also the communication platform connecting the outside world to the cell’s interior control centers. Thousands of proteins reside in these cell membranes and control the flow of select chemicals, which move across the barrier and mediate the flux of nutrients and information. Almost all of these pathways work...
