Plant death may reveal genetic mechanisms underlying cell self-destruction

Hybrid plants, which produced by crossing two different types of parents, often die in conditions in which both parents would survive. Certain hybrid tobacco plants, for example, thrive at 36 degrees Celsius, but die at 28 degrees Celsius, which is the temperature at which both parents would thrive. Researchers have begun to unravel the molecular mechanisms by which hybrid tobacco plant cells meet their demise.

Protein associated with many diseases fully visualized for first time

For the first time, researchers have learned at the molecular level how the P2X7 protein receptor – which is associated with inflammation, coronary artery disease, cancer, multiple sclerosis and more – works. The findings could one day inspire new drugs to treat numerous medical conditions.
