Plant communication

Author:      unterman
Text:        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?

Text:        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.
