Phytosemiotics is a branch of biosemiotics that studies the sign processes in plants, or more broadly, the vegetative semiosis. Vegetative semiosis is a type of sign processes that occurs at cellular and tissue level, including cellular recognition, plant perception, plant signal transduction, intercellular communication, immunological processes, etc.
The term 'phytosemiotics' has been introduced by Martin Krampen in 1981.
