Ion Channels and Plant Stress Responses

This book aims to provide a range of perspectives on an area that is very topical at present in plant biology: the role of ion channels in plant stress responses. Functions of cation and anion channels in the sensing and encoding of major biotic and abiot

Preface

Plants live in a constantly changing environment from which they cannot physically escape. Plants therefore need signalling and response mechanisms to adapt to new local conditions. The efficacy of such mechanisms underlies the plant performance during stress and therefore also impacts greatly on agricultural productivity. Modulation of ion channel activity not only provides a means for rapid signal generation but also allows adjustment of cellular physiology. For example, Ca2+ permeable ion channels can transduce environmental stimuli into Ca2+-encoded messages which can modify the gene expression. Furthermore, ion channel activity is essential to control cellular ion homeostasis that impacts on plant responses to drought, salinity, pathogens, nutrient deficiency, heavy metals, xenobiotics and other stresses. This volume focuses on the crucial roles of different types of ion channel in plant stress responses. Functions of ion channels are discussed in the context of mechanisms to relay external and endogenou
