Eftersom frågan aktualiserats samlar jag några gamla trådar jag hittar här om växters kommunikation.
Lägg gärna in fler länkar, om ni hittar.
Växter kanske kommunicerar med ljudvågor?:
"“We have previously suggested that acoustic signals may offer such a mechanism for mediating plant-plant relationships,” they explained in their conclusion (PDF), “and proposed that such signals may be generated in plants by biochemical processes within the cell, where nanomechanical oscillations of various components in the cytoskeleton can produce a spectrum of vibrations.”"

Bl.a. denna länk:
"Researchers may have discovered a previously unknown form of plant chatter that allows parasitic species and their hosts to share an astonishing amount of genetic information. The finding is exciting not only because it opens up an intriguing new field of research, but it could also lead to the development of novel strategies to tackle parasitic weeds that threaten food crops. The study has been published in Science."
