New discovery in how plants fight toxins (10/5/2007)

Although plants lack humans' T cells and other immune-function cells to signal and fight infection, scientists have known for more than 100 years that plants still somehow signal that they have been attacked in order to trigger a plantwide resistance. Now, researchers at the Boyce Thompson Institute for Plant Research (BTI) on the Cornell campus have identified the elusive signal in the process: methyl salicylate, an aspirin-like compound that alerts a plant's immune system to shift into high gear. ...> Full Article
