Plant Communication from an Ecological Perspective

Exploring plant communication within an ecological context, this volume aims to enhance the understanding of the interactions between plants and other organisms. A broader perspective of the field is presented here, and represents a valuable reference work on the current state of research.

Since the concept of allelopathy was introduced almost 100 years ago, research has led to an understanding that plants are involved in complex communicative interactions. They use a battery of different signals that convey plant-relevant information within plant individuals as well as between plants of the same species or different species. The 13 chapters of this volume discuss all these topics from an ecological perspective. Communication between plants allows them to share physiological and ecological information relevant for their survival and ?tness. It is obvious that in these very early days of ecological plant communication research we are illuminating only the 'tip of iceberg' of the communicative nature of higher plants. Nevertheless, knowledge on the identity and informative value of volatiles used by plants for communication is increasing with breath-taking speed. Among the most spectacular examples are sit- tions where plant emitters warn neighbours about a danger, increasing their innate immunity, or when herbivore-attacked plants attract the enemies of the herbivores ('cry for help' and 'plant bodyguards' concepts). It is becoming obvious that plants use not only volatile signals but also diverse water soluble molecules, in the case of plant roots, to safeguard their evolutionary success and accomplish self/non-self kin rec- nition. Importantly, as with all the examples of biocommunication, irrespective of whether signals and signs are transmitted via physical or chemical pathways, plant communication is a rule-governed and sign-mediated process.

This book shows the complexity of plant signaling and behavior in an ecological context and is intended to increase our understanding of it. It reflects the multifaceted interactions between plants and other organisms that affect their growth and development. In addition it puts emphasis on the effects of plant signaling and behavior on other trophic levels. This field of research is growing and developing rapidly, and new findings are regularly reported. Thus, this book provides a broader view of the field and represents a valuable reference work on the current state of research.
