Left: A blue light pulse of 0.1 seconds triggers a calcium signal (red) in guard cells, which is followed by an anion current (black). Right: The influx of calcium into the cell promotes the release ...

Using optogenetics, researchers have detected a new acid sensor in plant cells that is addressing a cell-internal calcium store. When plants are infected by pathogens, suffer from a lack of water or ...

UNIVERSITY PARK, Pa. — A new computational pipeline for analyzing three-dimensional imaging data can help biologists more accurately and quickly see how the cells in a plant’s leaves respond to the ...

Researchers have identified a 'guard mechanism' for a protein which attacks microbes in infected cells, opening the possibility of new treatments for Toxoplasma, Chlamydia, Tuberculosis and even ...
