Plants are sessile, highly sensitive organisms that actively compete for environmental resources both above and below the ground. They assess their surroundings, estimate how much energy they need for particular goals, and then realise the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between ˜self' and ˜non-self'. They process and evaluate information and then modify their behaviour accordingly. These highly diverse competences are made possible by parallel sign(alling)-mediated communication processes within the plant body (intraorganismic), between the same, related and different species (interorganismic), and between plants and non-plant organisms (transorganismic). Intraorganismic communication involves sign-mediated interactions within cells (intracellular) and between cells (intercellular). This is crucial in coordinating growth and development, shape and dynamics. Such communication must function both on the local level and between widely separated plant parts. This allows plants to coordinate appropriate response behaviours in a differentiated manner, depending on their current developmental status and physiological influences. Lastly, this volume documents how plant ecosphere inhabitants communicate with each other to coordinate their behavioural patterns, as well as the role of viruses in these highly dynamic interactional networks.

Lipid rafts-discrete regions in cell membranes that are rich in cholesterol and sphingolipids-are emerging not only as pivotal command and control centers for cellular signaling processes, but also as central to a wide array of human diseases, including immune disorders, diabetes, cardiovascular disease, and Alzheimer's disease. In Membrane Microdomain Signaling: Lipid Rafts in Biology and Medicine, multidisciplinary experts offer cutting-edge reviews of our current understanding of these membrane microdomains and their physiological and pathological roles. Here, readers will discover how lipid rafts change in cells over time and how they respond to various environmental signals, how cholesterol modulates the signaling function of lipid rafts, and how lipid rafts, the extracellular matrix, and the cell cytoskeleton structurally interact. Also described are the role of lipid rafts in learning, memory, and cancer, and as portals for endocytic uptake of an anticancer- and apoptotic alkyl-lysophospholipid. The authors also present emerging evidence that lipid rafts play critical roles in signaling pathways and the regulation of synaptic function in the nervous system, and that alterations in lipid raft metabolism are implicated in the pathogenesis of neurodegenerative disorders. They also describe techniques for the isolation of lipid rafts, the analysis of the lipid and protein components of lipid rafts, the imaging of lipid rafts in living cells, and the analysis of signal transduction in lipid rafts. Comprehensive and insightful, Membrane Microdomain Signaling: Lipid Rafts in Biology and Medicine offers researchers a multidisciplinary review of the latest basic, translational, and clinical research that promises to transform our understanding microdomain signaling mechanisms.

Plant neurobiology is a newly emerging field of plant sciences. It covers signalling and communication at all levels of biological organization – from molecules up to ecological communities. In this book, plants are presented as intelligent and social organisms with complex forms of communication and information processing. Authors from diverse backgrounds such as molecular and cellular biology, electrophysiology, as well as ecology treat the most important aspects of plant communication, including the plant immune system, abilities of plants to recognize self, signal transduction, receptors, plant neurotransmitters and plant neurophysiology. Further, plants are able to recognize the identity of herbivores and organize the defence responses accordingly. The similarities in animal and plant neuronal/immune systems are discussed too. All these hidden aspects of plant life and behaviour will stimulate further intense investigations in order to understand the communicative plants in their whole complexity.
