Achieving zero hunger and food security is a top priority in the United Nations Development Goals (UNDGs). In an era characterized by high population growth and increasing pressure on agricultural systems, efficiency in the use of natural resources has become central to sustainable agricultural practices. Fundamentally speaking, eco-efficiency is about maximizing agricultural outputs, in terms of quantity and quality, using less land, water, nutrients, energy, labor, or capital. The concept of eco-efficiency involves both the ecological and economic aspects of sustainable agriculture. It is therefore essential to understand the interaction of ecosystem constituents within the extensive agricultural landscape, as well as farmers'economic needs.This book examines the latest eco-efficient practices used in agro-systems. Drawing upon research and examples from around the world, it offers an up-to-date overview, together with insights into directly applicable approaches for poly-cropping systems and landscape-scale management to improve the stability of agricultural production systems, helping achieve food security. The book will be of interest to educators, researchers, climate change scientists, capacity builders and policymakers alike. It can also be used as additional reading material for undergraduate and graduate courses on agriculture, forestry, soil science, and the environmental sciences.

This book discusses central concepts and theories in cell biology from the ancient past to the 21st century, based on the premise that understanding the works of scientists like Hooke, Hofmeister, Caspary, Strasburger, Sachs, Schleiden, Schwann, Mendel, Nemec, McClintock, etc. in the context of the latest advances in plant cell biology will help provide valuable new insights.Plants have been an object of study since the roots of the Greek, Chinese and Indian cultures. Since the term “cell” was first coined by Robert Hooke, 350 years ago in Micrographia, the study of plant cell biology has moved ahead at a tremendous pace. The field of cell biology owes its genesis to physics, which through microscopy has been a vital source for piquing scientists'interest in the biology of the cell. Today, with the technical advances we have made in the field of optics, it is even possible to observe life on a nanoscale. From Hooke's observations of cells and his inadvertent discovery of the cell wall, we have since moved forward to engineering plants with modified cell walls. Studies on the chloroplast have also gone from Julius von Sachs'experiments with chloroplast, to using chloroplast engineering to deliver higher crop yields. Similarly, advances in fluorescent microscopy have made it far easier to observe organelles like chloroplast (once studied by Sachs) or actin (observed by Bohumil Nemec). If physics in the form of cell biology has been responsible for one half of this historical development, biochemistry has surely been the other.

This book focuses on the fundamentals of plant physiology for undergraduate and graduate students. It consists of 34 chapters divided into five major units. Unit I discusses the unique mechanisms of water and ion transport, while Unit II describes the various metabolic events essential for plant development that result from plants'ability to capture photons from sunlight, to convert inorganic forms of nutrition to organic forms and to synthesize high energy molecules, such as ATP. Light signal perception and transduction works in perfect coordination with a wide variety of plant growth regulators in regulating various plant developmental processes, and these aspects are explored in Unit III. Unit IV investigates plants'various structural and biochemical adaptive mechanisms to enable them to survive under a wide variety of abiotic stress conditions (salt, temperature, flooding, drought), pathogen and herbivore attack (biotic interactions). Lastly, Unit V addresses the large number of secondary metabolites produced by plants that are medicinally important for mankind and their applications in biotechnology and agriculture. Each topic is supported by illustrations, tables and information boxes, and a glossary of important terms in plant physiology is provided at the end.

This book provides important insights into the operating principles of plants by highlighting the relationship between structure and function. It describes the quantitative determination of structural and mechanical parameters, such as the material properties of a tissue, in correlation with specific features, such as the ability of the tissue to conduct water or withstand bending forces, which will allow advanced analysis in plant biomechanics. This knowledge enables researchers to understand the developmental changes that occur in plant organs over their life span and under the influence of environmental factors. The authors provide an overview of the state of the art of plant structure and function and how they relate to the mechanical behavior of the organism, such as the ability of plants to grow against the gravity vector or to withstand the forces of wind. They also show the sophisticated strategies employed by plants to effect organ movement and morphogenesisin the absence of muscles or cellular migration. As such, this book not only appeals to scientists currently working in plant sciences and biophysics, but also inspires future generations to pursue their own research in this area.

Glutathione (γ-glutamyl-cysteinyl-glycine) is a ubiquitously distributed sulfurcontaining antioxidant molecule that plays key roles in the regulation of plant growth, development, and abiotic and biotic stress tolerance. It is one of the most powerful low-molecular-weight thiols, which rapidly accumulates in plant cells under stress. Recent in-depth studies on glutathione homeostasis (biosynthesis, degradation, compartmentalization, transport, and redox turnover) and the roles of glutathione in cell proliferation and environmental stress tolerance have provided new insights for plant biologists to conduct research aimed at deciphering the mechanisms associated with glutathione-mediated plant growth and stress responses, as well as to develop stress-tolerant crop plants. Glutathione has also been suggested to be a potential regulator of epigenetic modifications, playing important roles in the regulation of genes involved in the responses of plants to changing environments. The dynamic relationship between reduced glutathione (GSH) and reactive oxygen species (ROS) has been well documented, and glutathione has been shown to participate in several cell signaling and metabolic processes, involving the synthesis of protein, the transport of amino acids, DNA repair, the control of cell division, and programmed cell death. Two genes, gamma-glutamylcysteine synthetase (GSH1) and glutathione synthetase (GSH2), are involved in GSH synthesis, and genetic manipulation of these genes can modulate cellular glutathione levels. Any fluctuations in cellular GSH and oxidized glutathione (GSSG) levels have profound effects on plant growth and development, as glutathione is associated with the regulation of the cell cycle, redox signaling, enzymatic activities, defense gene expression, systemic acquired resistance, xenobiotic detoxification, and biological nitrogen fixation. Being a major constituent of the glyoxalase system and ascorbate-glutathione cycle, GSH helps to control multiple abiotic and biotic stress signaling pathways through the regulation of ROS and methylglyoxal (MG) levels. In addition, glutathione metabolism has the potential to be genetically or biochemically manipulated to develop stress-tolerant and nutritionally improved crop plants. Although significant progress has been made in investigating the multiple roles of glutathione in abiotic and biotic stress tolerance, many aspects of glutathione-mediated stress responses require additional research.The main objective of this volume is to explore the diverse roles of glutathione in plants by providing basic, comprehensive, and in-depth molecular information for advanced students, scholars, teachers, and scientists interested in or already engaged in research that involves glutathione. Finally, this book will be a valuable resource for future glutathione-related research and can be considered as a textbook for graduate students and as a reference book for frontline researchers working on glutathione metabolism in relation to plant growth, development, stress responses, and stress tolerance.

This book explores various nanotechnology applications and their effect on the food industry, innovation and environmental issues.

Ascorbic acid (AsA), vitamin C, is one of the most abundant water-soluble antioxidant in plants and animals. In plants AsA serves as a major redox buffer and regulates various physiological processes controlling growth, development, and stress tolerance. Recent studies on AsA homeostasis have broadened our understanding of these physiological events. At the mechanistic level, AsA has been shown to participate in numerous metabolic and cell signaling processes, and the dynamic relationship between AsA and reactive oxygen species (ROS) has been well documented. Being a major component of the ascorbate-glutathione (AsA-GSH) cycle, AsA helps to modulate oxidative stress in plants by controlling ROS detoxification alone and in co-operation with glutathione. In contrast to the single pathway responsible for AsA biosynthesis in animals, plants utilize multiple pathways to synthesize AsA, perhaps reflecting the importance of this molecule to plant health. Any fluctuations, increases or decreases, in cellular AsA levels can have profound effects on plant growth and development, as AsA is associated with the regulation of the cell cycle, redox signaling, enzyme function and defense gene expression. Although there has been significant progress made investigating the multiple roles AsA plays in stress tolerance, many aspects of AsA-mediated physiological responses require additional research if AsA metabolism is to be manipulated to enhance stress-tolerance. This book summarizes the roles of AsA that are directly or indirectly involved in the metabolic processes and physiological functions of plants. Key topics include AsA biosynthesis and metabolism, compartmentation and transport, AsA-mediated ROS detoxification, as well as AsA signaling functions in plant growth, development and responses to environmental stresses. The main objective of this volume is therefore to supply comprehensive and up-to-date information for students, scholars and scientists interested in or currentlyengaged in AsA research.

Comment les plantes poussent-elles? Le nombre d'or est-il omniprésent dans leur architecture? Leurs structures sont-elles fractales? Ont-elles un langage? Une grammaire? Il y a du vrai dans ces questions, mais il faut aller plus loin. Il faut identifier, modéliser et simuler le rôle des organes d'une plante dans sa croissance et leur fonctionnement.La modélisation des plantes fait l'objet de recherches à l'interface de disciplines biologiques (botanique, agronomie, génétique, écophysiologie) des mathématiques appliquées et de l'informatique. Elle permet de créer les modèles de développement de l'architecture des plantes, mais aussi les modèles de production végétale, expression de la croissance des organes.Les auteurs de cet ouvrage nous exposent les fondements biologiques, mathématiques et informatiques qui permettent d'exprimer le fonctionnement des bourgeons, la production photosynthétique de la biomasse et sa répartition dans les organes d'une plante. La simulation de la croissance des plantes devient alors possible sous la forme de modèles dynamiques et sa représentation, sous la forme d'images de synthèse. Ces modèles autorisent de multiples applications. De nombreuses plantes sont présentées (herbacées, arbustes et arbres) ; leur modélisation a une visée pratique en agriculture, en gestion des ressources naturelles et de l'environnement et en représentation des paysages.Rédigé par des botanistes, des agronomes, des mathématiciens et des informaticiens, cet ouvrage collectif est le fruit de quarante années de recherches conduites par Philippe de Reffye et ses collègues, avec des collaborations scientifiques en France, en Hollande, en Chine et en Afrique. Il s'adresse aux chercheurs, enseignants et étudiants en biologie, en agronomie et en sciences de la vie, aux architectes paysagistes, écologues, qui s'intéressent à la croissance des plantes, à leur modélisation et à leur représentation. Il s'adresse aussi à toutes les communautés des sciences exactes (mathématiciens, informaticiens, physiciens) intéressées par la simulation du vivant. Une version plus synthétique de ce livre est disponible sous le titre Architecture des plantes et production végétale. Les apports de la modélisation mathématique ; elle rend compte des principaux fondements de la modélisation des plantes, pour mieux la connaître. DOI : https://doi.org/10.19182/quae/00001

Jasmonic acid (JA) is an essential phytohormone for plant development and stress response. It not only acts as the regulatory molecule in root elongation, germination, pollen production, fruit ripening and plant senescence, but also acts as the signaling compound activating plant defenses against pathogens, herbivory, wounding and abiotic stress. This book discusses the biosynthesis, functions and the role jasmonic acid has in plant development.

This book focuses on early germination, one of maize germplasm most important strategies for adapting to drought-induced stress. Some genotypes have the ability to adapt by either reducing water losses or by increasing water uptake. Drought tolerance is also an adaptive strategy that enables crop plants to maintain their normal physiological processes and deliver higher economical yield despite drought stress. Several processes are involved in conferring drought tolerance in maize: the accumulation of osmolytes or antioxidants, plant growth regulators, stress proteins and water channel proteins, transcription factors and signal transduction pathways. Drought is one of the most detrimental forms of abiotic stress around the world and seriously limits the productivity of agricultural crops. Maize, one of the leading cereal crops in the world, is sensitive to drought stress. Maize harvests are affected by drought stress at different growth stages in different regions. Numerous events in the life of maize crops can be affected by drought stress: germination potential, seedling growth, seedling stand establishment, overall growth and development, pollen and silk development, anthesis silking interval, pollination, and embryo, endosperm and kernel development. Though every maize genotype has the ability to avoid or withstand drought stress, there is a concrete need to improve the level of adaptability to drought stress to address the global issue of food security. The most common biological strategies for improving drought stress resistance include screening available maize germplasm for drought tolerance, conventional breeding strategies, and marker-assisted and genomic-assisted breeding and development of transgenic maize. As a comprehensive understanding of the effects of drought stress, adaptive strategies and potential breeding tools is the prerequisite for any sound breeding plan, this brief addresses these aspects.

Programmed cell death (PCD) is a genetically encoded, active process which results in the death of individual cells, tissues, or whole organs. PCD plays an essential role in plant development and defense, and occurs throughout a plant's lifecycle from the death of the embryonic suspensor to leaf and floral organ senescence. In plant biology, PCD is a relatively new research area, however, as its fundamental importance is further recognized, publications in the area are beginning to increase significantly. The field currently has few foundational reference books and there is a critical need for books that summarizes recent findings in this important area. This book contains chapters written by several of the world's leading researchers in PCD. This book will be invaluable for PhD or graduate students, or for scientists and researchers entering the field. Established researchers will also find this timely work useful as an up-to-date overview of this fascinating research area.

Salicylic acid (SA) and methyl jasmonate (MJ) signaling is associated with phospholipids and the enzymes that metabolize them. However, despite the many studies conducted, the role of SA or MJ signaling via phospholipids in plant responses is not yet fully understood. The signaling pathways of SA and MJ have been evaluated in plant cell suspensions, and it was observed that these compounds regulate enzymatic activities to generate a rapid cellular response. This book discusses the immune responses induced by salicylic acid and jasmonic acids against plant parasites; the induction by SA of in vitro thermotolerance during thermotherapy; aalicylic acid, methyl jasmonate and phospholipid signaling in suspension cells; the self-association of salicylic acid derivatives in aqueous solutions studied by methods of absorption and fluorescence; and the role of exogenous salicylic acid applications for salt tolerance in tomato plants.

Plant hormones playa crucial role in controlling the way in which plants grow and develop. While metabolism provides the power and building blocks for plant life it is the hormones that regulate the speed of growth of the individual parts and integrate these parts to produce the form that we recognize as a plant. In addition, they playa controlling role in the processes of reproduction. This book is a description of these natural chemicals: how they are synthesized and metabolized; how they work; how we measure them; and a description of some of the roles they play in regulating plant growth and development. This is not a conference proceedings but a selected collection of newly written, integrated, illustrated reviews describing our knowledge of plant hormones and the experimental work which is the foundation of this knowledge. The information in these pages is directed at advanced students and professionals in the plant sciences: botanists, biochemists, molecular biologists, or those in the horticultural, agricultural and forestry sciences. It is intended that the book should serve as a text and guide to the literature for graduate level courses in the plant hormones, or as a part of courses in plant or comparative development. Scientists in other disciplines who wish to know more about the plant hormones and their role in plants should also find this volume invaluable It is hoped that anyone with a reasonable scientific background can find valuable information in this book expounded in an understandable fashion.
