The book will describe the xylem structure of different plant groups, and will put the findings in a physiological and ecological context. For instance, when differences in vessel diameter are featured, then there will be an explanation why this matters for water transport efficiency and safety from cavitation. The focus is on the hydraulic function of xylem, although mechanical support and storage will also be covered. Featured plant groups include ferns (which only have primary xylem), conifers (tracheid-based xylem), lianas (extremely wide and long vessels), drought-adapted shrubs as well as the model systems poplar and grapevine. The book chapters will draw on the expertise and cutting edge research of a diversified group of internationally known researchers working in different anatomical and physiological sub-disciplines. Over the last two decades, much progress has been made in understanding how xylem structure relates to plant function. Implications for other timely topics such as drought-induced forest dieback or the regulation of plant biomass production will be discussed.

This is the first volume to provide comprehensive coverage of the biology of water use efficiency at molecular, cellular, whole plant and community levels. While several works have included the phenomenon of water use efficiency, and others have concentrated on an agronomic framework, this book represents the first detailed treatment with a biological focus.

The volume sets out the definitions applicable to water use efficiency, the fundamental physiology and biochemistry governing the efficiency of carbon" vs "water loss, the environmental regulation of this process and the detailed physiological basis by which the plant exerts control over such efficiency. It is aimed at researchers and professionals in plant physiology, biochemistry, molecular biology, developmental biology and agriculture. It will also inform those involved in formulating research and development policy in this topic around the world.

The aim of this monograph is to highlight various mechanisms followed by plants to overcome the high light stress and photoinhibition, and also the plant responses to low light levels. Emphasis has been on the regulation of light harvesting process, the avoidance phenomena at leaf and chloroplast levels and the strategy followed by certa in solar tracking plants in maximizing the light interception without photoinhibitory damage, leading to improvement of diurnal photosynthetic rate. Plant adjustment to light variations over a long term, through the acclimation process brought about by changes in gene function and specific reconstruction of chloroplast has also been discussed. Although the emphasis has been on higher plant systems, green algae and cyanobacterial examples are used wherever appropriate. This book will be a useful reference to advanced postgraduate students, research scientists and teachers interested in the area of photosynthesis research.

Coupled with biomechanical data, organic geochemistry and cladistic analyses utilizing abundant genetic data, scientific studies are revealing new facets of how plants have evolved over time.

Eucalyptus, a genus of over 800 species, is a multiproduct crop par excellence. Not only is it grown for timber, pulp and fuelwood but, as the Aborigines discovered thousands of years ago, it has numerous medicinal and aromatic properties. Since the first commercial distillation of eucalyptus oil 150 years ago, a vast array of eucalyptus-based products has entered the marketplace, mainly for pharmaceutical, fragrance and flavour use.
This book provides an invaluable reference for all those with an interest in Eucalyptus - in academia and industry alike, for researchers as well as producers, processors, importers and end users - but there are also issues discussed and lessons learnt which extend to medicinal and aromatic plants generally.

Plants depend for their survival on physiological mechanisms with which to combat adverse environmental conditions, such as pathogen attack, wounding, drought, cold, freezig, salt, UV, intense light, hevy metals, and SO2. Many of these cause excess production of active oxygen species in plant cells. Plants in turn have evolved complex defence systems against such oxidative stress. The study of these mechanisms has become a fast-moving, topical firld of importance to many biologists studying the effect of the environment on living organisms.
Written and edited by world-leading scientists, Oxidative Stress in Plants reviews the current knowledge of the mechanisms by which various biotic and abiotic environmental stress conditions produce oxygen eadicals. The biochemistry and molecular biology of both non-enzymatic (Vitamin C; Glutathione) and enzymatic systems which eliminate active oxygen species are considered in detail. In addition, the book discusses evidence that active oxygen species and antioxidants act as signals which trigger defence reactions.

Current trends in population growth hint that global food production is unlikely to gratify future demands under predicted climate change scenarios unless the rates of crop improvement are accelerated. Crop production faces numerous challenges, due to changing environmental conditions and evolving needs for new plant-derived materials. These challenges come at a time when the plant sciences are witnessing remarkable progress in understanding fundamental processes of plant growth and development. Drought, heat, cold and salinity are among the major abiotic stresses that often cause a series of morphological, physiological, biochemical and molecular alterations which adversely affect plant growth, development andproductivity, consequently posing a serious challenge for sustainable food production in large parts of the world, particularly in emerging countries. This emphasizes the urgency of finding better ways to translate new advances in plant science into concrete successes in agricultural production. To overcome the pessimistic influence of abiotic stresses and to maintain the food security in the face of these challenges, new, improved and tolerant crop varieties, contemporary breeding techniques, and cavernous understanding of the mechanisms that counteract detrimental climate changes are indubitably needed to sustain the requisite food supply. In this context, "Improvement of Crops in the Era of Climatic Changes, Volume 1 "provides a state-of-the-art guide to recent developments that aid in the understanding of plant responses to abiotic stresses and lead to new horizons vis-a-vis prime strategies for translating current researchinto applied solutions to create strong yields and overall crop improvement under such unfavourable environments.

Written by a diversegroup of internationally famed scholars, "Improvement of Crops in the Era of Climatic Changes, Volume 1" is a brief yet all-inclusive resource that is immensely advantageous for researchers, students, environmentalists, soil scientists, professionals, and many others in the quest of advancement in this flourishing field of research."

The past decade has seen major advances in the cloning of genes encoding enzymes of plant secondary metabolism.

The chapters cover five major topics: 1. Role of secondary metabolites in evolution; 2. Evolutionary origins of polyketides and terpenes; 3. Roles of oxidative reactions in the evolution of secondary metabolism; 4. Evolutionary origin of substitution reactions: acylation, glycosylation and methylation; and 5. Biochemistry and molecular biology of brassinosteroids.

This book presents a comprehensive and coherent picture of how molecules diffuse across a liquid that is, on average, only two molecules thick. It begins by characterizing bilayers structurally, using X-ray diffraction, and then mechanically by measuring elastic moduli and mechanisms of failure. Emphasis is placed on the stability and mechanical properties of plant membranes that are subject to very large osmotic and thermal stresses. Using this information, the transport of molecules of increasing complexity across bilayers is analyzed.

This text is intended for plant physiologists, molecular biologists, biochemists, biotechnologists, geneticists, horticulturalists, agromnomists and botanists, and upper-level undergraduate and graduate students in these disciplines. It integrates advances in the diverse and rapidly-expanding field of seed science, from ecological and demographic aspects of seed production, dispersal and germination, to the molecular biology of seed development. The book offers a broad, multidisciplinary approach that covers both theoretical and applied knowledge.
