Recently, in a non-technical journal (like Science News), there appeared an article stating that a stressed plant would emit a hormonal/chemical signal causing proximate plants to alter their chemistry defensively. What technical journal did this originally appear in, and is this valid?

I have also read about this but years ago. I believe it is well established that plants communicate with airborne semiochemicals. I do not know the journal but perhaps a librarian could help you hunt it down on a computer database, or try a forestry textbook.
