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.
