I read an article earlier that if a plant gets infected with a 
diesease(or virus) then they will let of gases in the air to warn 
other plants. The other plants will recieve the signal and it will 
increase their immune system and it will be immune to that diesease. 
Is this true, and is it possible to conduct a science fair project 
through this? If it is possible please tell me how. Thanks for your 
time.
