Plant stresses are serious threats to the sustainability of crop yields accounting for more crop productivity losses than any other factor in rainfed agriculture. Post-harvest losses mean surplus crops do not reach market, affecting the livelihoods of farming families, and too often these families are left with no other option than to eat contaminated stored food. These constraints impact the food security of these farming families as well as the communities and countries in which they live. This book is the demonstration of a clear synergistic effect of stresses, an effect that was unexpectedly as important as either stress applied alone. This book will add to our current knowledge of abiotic stress response in plants and will provide the groundwork necessary to build future strategies for crop enhancement. The fundamental principles that underpin all biotechnology are explained and a full range of examples discussed to show how these principles are applied; from starting substrate to final product. It will be beneficial to both plant breeders and molecular biologists, because it combines the topics of physiology, tolerance genes, and breeding methods. When these topics are presented together, it is easy to compare all aspects of tolerance mechanisms and breeding methods for abiotic stresses. These comparisons are useful to understand which pathways or which genes are important for rendering more tolerance to a certain abiotic stress, and to bring forward new ideas for improving the tolerance. Features •Cover both plant biotic and abiotic stresses •Important factors in managing crops for water stress conditions •Substantially increase the sustainable productivity of smallholder farmers in developing countries •Genetic and biochemical approaches – if those approaches constitute a substantial improvement on current practices.

This book, Biotic Stress Management in Rice: Molecular Approaches, addresses biotic stress of rice and its management through molecular approaches. It focuses on the biotechnological aspects of rice with the aim of reducing the fungicide and insecticides and ultimately ensuring safety of rice as a food as well as the environment. Rice is an important crop in much of the Asia-Pacific region, and there are a number of threats to rice production, including fungal, viral, and bacterial diseases and insect pests, both in temperate and tropical countries, which can cause the significant economic loss. Remarkable efforts are being made by scientists and breeders to raise rice productivity and safety by modifying and manipulating rice plants to survive under different types of stresses. The book provides an understanding of the genetic basis of resistance and susceptibility and goes on to present studies directed to understand the host-plant interaction in rice that have given rise to specialized breeding programs for resistance to diseases and insect-pests. In addition to these advancements in molecular breeding, marker-assisted selection and transgenic approaches open new ways to increase resistance in rice for better production under several biotic stresses. This book covers the most recent advancements and research strategies of molecular breeding, transgenic approaches, and other tools for effective biotic stress management in rice. This book should find a prominent place on the shelves of new plant breeders, biotechnologists, plant pathologists and entomologists working in academic and commercial rice research programs, and in the libraries of research establishments.

The broad host range pathogenic bacterium Agrobacterium tumefaciens has been widely studied as a model system to understand horizontal gene flow, secretion of effector proteins into host cells, and plant-pathogen interactions. Agrobacterium-mediated plant transformation also is the major method for generating transgenic plants for research and biotechnology purposes. Agrobacterium species have the natural ability to conduct interkingdom genetic transfer from bacteria to eukaryotes, including most plant species, yeast, fungi, and even animal cells. In nature, A. tumefaciens causes crown gall disease resulting from expression in plants of auxin and cytokinin biosynthesis genes encoded by the transferred (T-) DNA. Gene transfer from A. tumefaciens to host cells requires virulence (vir) genes that reside on the resident tumor-inducing (Ti) plasmid. In addition to T-DNA, several Virulence (Vir) effector proteins are also translocated to host cells through a bacterial type IV secretion system. These proteins aid in T-DNA trafficking through the host cell cytoplasm, nuclear targeting, and T-DNA integration. Genes within native T-DNAs can be replaced by any gene of interest, making Agrobacterium species important tools for plant research and genetic engineering. In this research topic, we provided updated information on several important areas of Agrobacterium biology and its use for biotechnology purposes.

Plants have to manage a series of environmental stresses throughout their entire lifespan. Among these, abiotic stress is the most detrimental; one that is responsible for nearly 50% of crop yield reduction and appears to be a potential threat to global food security in coming decades. Plant growth and development reduces drastically due to adverse effects of abiotic stresses. It has been estimated that crop can exhibit only 30% of their genetic potentiality under abiotic stress condition. So, this is a fundamental need to understand the stress responses to facilitate breeders to develop stress resistant and stress tolerant cultivars along with good management practices to withstand abiotic stresses. Also, a holistic approach to understanding the molecular and biochemical interactions of plants is important to implement the knowledge of resistance mechanisms under abiotic stresses. Agronomic practices like selecting cultivars that is tolerant to wide range of climatic condition, planting date, irrigation scheduling, fertilizer management could be some of the effective short-term adaptive tools to fight against abiotic stresses. In addition, “system biology” and “omics approaches” in recent studies offer a long-term opportunity at the molecular level in dealing with abiotic stresses. The genetic approach, for example, selection and identification of major conditioning genes by linkage mapping and quantitative trait loci (QTL), production of mutant genes and transgenic introduction of novel genes, has imparted some tolerant characteristics in crop varieties from their wild ancestors. Recently research has revealed the interactions between micro-RNAs (miRNAs) and plant stress responses exposed to salinity, freezing stress and dehydration. Accordingly transgenic approaches to generate stress-tolerant plant are one of the most interesting researches to date. This book presents the recent development of agronomic and molecular approaches in conferring plant abiotic stress tolerance in an organized way. The present volume will be of great interest among research students and teaching community, and can also be used as reference material by professional researchers.

Understanding biotic stress and plant yield allows for the practical development of economic decision making, an instrumental part of Integrated Pest Management. And further, the impact of biotic injury on plant yield bears directly on the basic biological questions of population dynamics, life history strategies, community structure, plant-stressor coevolution, and ecosystem nutrient cycling. Biotic Stress and Yield Loss is a comprehensive review of the latest conclusions of yield loss in entomology, weed science, and plant pathology, combining state-of-the-art theory with successful applications. This book is unique in that it is the first to cover all biotic stressors, insects, weeds, and plant pathogens, and their impact on plant yield and fitness. It focuses on current knowledge of yield and fitness loss in both natural and agricultural ecosystems and on a physiologically based approach to provide a common basis for considering and discussing biotic stress. By considering biotic stress within the context of plant ecophysiology, Biotic Stress and Yield Loss attempts to elevate knowledge of biotic stress to the same level as abiotic stress and makes an argument for integrating the two types of stress.

Plants under abiotic stress are those suffering from drought, extreme temperatures, flood and other natural—but non-living—factors. Abiotic stress is responsible for reduced yields in several major crops, and climate change is focusing research in this area. To minimize cellular damage cause by such stresses, plants have evolved complex, well-coordinated adaptive responses that operate at the transcriptional level. Understanding these processes is key to manipulating plant performance to withstand stress. This book deals with the role of gene silencing in the adaptation of plants to these stresses, and documents the molecular regulatory systems for the abiotic response.
