That's what the title of an article in Discover Magazine (Vol 23, No. 4) proclaims. The evidence is mounting revealing that plants can actually give cries for help, invitations and even warnings to other plants in the local area. These communications are held through odor molocules that float right past the human nose. To give an example, A common crop pest Heliothis Virescens begins to feed on a tobaco plant. Chemicals in the caterpillar's saliva prompt the plant to release airbord chemical cues. Those signals in turn summon Cardiochiles nigiceps, a parasitic wasp that prefers to lay its eggs in H. virescens. Now that's COOL! The world around us is very connected indeed.
