Harmonious, integrated functioning of the whole plant system requires that its various cells, tissues and organs should be able to communicate with each other, transferring a range of information on environmental conditions, physiological and microbial stresses etc. In this volume of Advances in Botanical Research incorporating Advances in Plant Pathology three articles are concerned with different aspects of plant signalling. McDonald and Davis consider how shoot systems respond to drying and N-deficient soil, in terms of their stomatal behaviour and growth, via the transmission of root-derived chemical signals. Malone considers the major hypotheses that have been proposed with particular attention being given to hydraulic pressure signals and the hydraulic dispersal of chemical signals. At a different, intracellular level of communication, a wide variety of second messengers couple extracellular stimuli to a characteristic physiological response. Webb et al. Consider progress made in establishing similar roles for calcium in plant signalling in the context of the mammalian paradigms. The effects of UV-B radiation on plants have been extensively investigated in recent years. Jordan considers progress in understanding the chain of events from perception of UV-B to signal transduction and consequent changes in gene expression and regulation. Smith and Smith assess the various hypotheses erected over the years to explain structure and function of the host-parasite interface formed by vesticular-arbuscular (VA) mycorrhizas, an important and widespread mutualistic symbioses of a wide range of higher and some lower plants.

Annual Plant Reviews, Volume 14 It is difficult to over-state the importance of plant pigments in biology. Chlorophylls are arguably the most important organic compounds on earth, as they are required for photosynthesis. Carotenoids are also necessary for the survival of both plants and mammals, through their roles in photosynthesis and nutrition, respectively. The other plant pigment groups, such as flavonoids and betalains, have important roles in both the biology of plants and the organisms with which plants interact. This book provides an overview of pigment chemistry and biology, together with an up-to-date account of the biosynthesis of pigments and the modification of their production using biotechnology. The chapters cover a wide scope of pigmentation research - from the importance of structural diversity in generating the range of colours seen in plants, through to improving human health properties of crops by increasing pigment levels in transgenic plants. The volume is directed at researchers and professionals in plant biochemistry, molecular biology and genetics.

Radiation Measurement in Photobiology deals with the measurement of optical radiation and its application in photobiology. Optical radiation detectors as well as the calibration of light sources and detectors are discussed, together with techniques for spectroradiometry and broadband radiometry. Action spectroscopy and ultraviolet radiation dosimetry are also considered. Comprised of nine chapters, this volume begins with an introduction to the basic principles of light measurement, followed by a survey of optical radiation detectors based on physical principles and the problems associated with calibration. The next three chapters deal with important applications and extensions of these radiant measurements, including a short review of biological and medical users of lasers. The final three chapters on specialized studies and developments illustrate the wide diversity that exists in photobiology. These cover ultraviolet radiation dosimetry using polymer films, computer modeling of terrestrial ultraviolet radiation, and the "diffusion optics" in biological media. This book should be of interest to photobiologists.

This book is a general guide to radio tracking and activity monitoring with pulsed-signal radio tags. The most elementary tags are used to find the animal so that it can be watched, captured or monitored in other ways. Tags can also have their pulses modulated by a variety of simple sensor sub-circuits to telemeter temperature, posture, movement, compass orientation and other aspects of animal activity. The text follows a sequence designed to guide the novice user through all aspects of radio tagging from the planning of a project and the choice of equipment, through field techniques to data analysis. There are details on tag construction and mounting both externally and by implantation. This book will be invaluable to scientists in all branches of ecology and wildlife research, both in showing ways in which radio tagging can be of use and in giving practical details on how to use this technology.
