Sensory Biology Of Plants

Plants provide a source of survival for all life on this planet. They are able to capture solar energy and convert it into food, feed, wood and medicines. Though sessile in nature, over many millions of years, plants have diversified and evolved from lower to higher life forms, spreading from sea level to mountains, and adapting to different ecozones. They have learnt to cope with challenging environmental conditions and various abiotic and biotic factors. Plants have also developed systems for monitoring the changing environment and efficiently utilizing resources for growth, flowering and reproduction, as well as mechanisms to counter the impact of pests and diseases and to communicate with other biological systems, like microbes and insects. This book discusses the "awareness" of plants and their ability to gather information through the perception of environmental cues, such as light, gravity, water, nutrients, touch and sound, and stresses. It also explores plants' biochemical and molecular "computing" of the information to adjust their physiology and development to the advantage of the species. Further, it examines how plants communicate between their different organs and with other organisms, as well as the concepts of plant cognition, experience and memory, from both scientific and philosophical perspectives. Lastly, it addresses the phenomenon of death in plants. The epilogue presents an artist's view of the beauty of the natural world, especially plant "architecture". The book provides historical perspectives, comparisons with animal systems where needed, and general biochemical and molecular concepts and themes. Each chapter is selfcontained, but also includes cross talk with other chapters to offer an integrated view of plant life and allow readers to appreciate and admire the functioning of plant life from within and without. The book is a tribute by the Editor to his students, colleagues and co-workers and to those in whose labs he has worked.

This book brings together the scientific knowledge of the various cognitive skills studied in plants through a physiological approach. The importance of the theme makes this an indispensable book for students, teachers and other professionals in the biological sciences, agrarian sciences and some segments of the behavioral sciences. In addition to providing information on new discoveries in plant science, this book offers a basis for the development of new plant cultivation technology and broadens the horizons of scientific investigation in various areas of research. Using different knowledge bases, the book explains how plants perceive themselves and the environment, how they communicate internally and externally, as well as how they modify their behavior in consonance with the changes that occur in endogenous and environmental stimuli. Behavioral changes, in turn, are the basis of approaches to addressing the thematic field of memory and intelligence. It is a work filled with intriguing aspects of plant behavior, such as the sensory mechanisms of plants’ perception of sound, touch, smells, temperature, O2, O3, CO2, atmospheric pressure, NaCl, nutrients, electric and magnetic fields, water and relative humidity. In addition to those inanimate elements, the book also discusses the mechanisms of plant-plant, plant-microorganism and plant-animal perception, recognition and communication.

Our image of plants is changing dramatically away from passive entities merely subject to environmental forces and organisms that are designed solely for the accumulation of photosynthate. Plants are revealing themselves to be dynamic and highly sensitive organisms that actively and competitively forage for limited resources, both above and below ground, organisms that accurately gauge their circumstances, use sophisticated cost-benefit analysis, and take clear actions to mitigate and control diverse environmental threats. Moreover, plants are also capable of complex recognition of self and non-self and are territorial in behavior. They are as sophisticated in behavior as animals but their potential has been masked because it operates on time scales many orders of magnitude less than those of animals. Plants are sessile organisms. As such, the only alternative to a rapidly changing environment is rapid adaptation. This book will focus on all these new and exciting aspects of plant biology.

"Enough absorbing science to concede that plants continue to inspire and amaze us." —The Wall Street Journal How does a Venus flytrap know when to snap shut? Can it feel an insect's tiny, spindly legs? And how do cherry blossoms know when to bloom? Can they remember the weather? For centuries we have marveled at plant diversity and form—from Charles Darwin's early fascination with stems to Seymour Krelborn's distorted doting in Little Shop of Horrors. But now, in What a Plant Knows, the renowned biologist Daniel Chamovitz presents an intriguing and scrupulous look at how plants themselves experience the world—from the colors they see to the schedules they keep. Highlighting the latest research in genetics and more, he takes us into the inner lives of plants and draws parallels with the human senses to reveal that we have much more in common with sunflowers and oak trees than we may realize. Chamovitz shows how plants know up from down, how they know when a neighbor has been infested by a group of hungry beetles, and whether they appreciate the Led Zeppelin you've been playing for them or if they're more partial to the melodic riffs of Bach. Covering touch, sound, smell, sight, and even memory, Chamovitz encourages us to consider whether plants might even be aware. A rare inside look at what life is really like for the grass we walk on, the flowers we sniff, and the trees we climb, What a Plant Knows offers us a greater understanding of botany and science and our place in nature.

Thoroughly updated from root to leaf, this revised edition of the groundbreaking What a Plant Knows includes new revelations for lovers of all that is vegetal and verdant. Plants can hear—and taste things, too! The renowned biologist Daniel Chamovitz builds on the original edition to present an intriguing look at how plants themselves experience the world—from the colors they see to the schedules they keep, and now, what they do in fact hear and how they are able to taste. A rare inside look at what life is really like for the grass we walk on, the flowers we sniff, and the trees we climb, What a Plant Knows offers a greater understanding of their place in nature.

Studies on molecular biology of pathogens, infection process and disease resistance, have provided information essentially required to understand the vulnerable stages at which the pathogens can be tackled effectively and to adopt novel strategies to incorporate disease resistance genes from diverse sources and /or to induce resistance of cultivars with desirable agronomic attributes using biotic or abiotic agents. The nature of interaction between the gene products of the pathogen and plant appears to determine the outcome of the interaction resulting in either disease progression or suppression. Transgenic plants with engineered genes show promise for effective exploitation of this approach for practical application. Research efforts during the recent years to sequence the whole genomes of the pathogens and plants may lead to development of better ways of manipulating disease resistance mechanisms enabling the grower to achieve higher production levels and the consumer to enjoy safer food and agricultural products. Experimental protocols included in appropriate chapters will be useful for researchers and graduate students.

Our view of plants is changing dramatically. Rather than being only slowly responding organisms, their signaling is often very fast and signals, both of endogenous and exogenous origin, spread throughout plant bodies rapidly. Higher plants coordinate and integrate their tissues and organs via sophisticated sensory systems, which sensitively screen both internal and external factors, feeding them information through both chemical and electrical systemic long-distance communication channels. This revolution in our understanding of higher plants started some twenty years ago with the discovery of systemin and rapid advances continue to be made. This volume captures the current ‘state of the art’ of this exciting topic in plant sciences.
