Book Description

Changes in natural ecosystems can affect biodiversity on a global scale, which in turn affects global food production. Climate change develops under different environmental conditions such as high CO2 concentration, ultraviolet radiation, temperature, salinity, rainfall intensity, etc., causing an increase in the growth of new weeds and pathogens. All these factors alone and in complex can reduce growth, complicate photosynthesis, and reduce the physiological and biochemical responses of plants. On the other hand, studies in recent years have shown that the development of a dual strategy of breeding for stress tolerance and introducing stress tolerant plants into production systems to increase their resistance to various stresses is particularly relevant today. Therefore, research related to physiological, biochemical and molecular responses of plants is of paramount importance to authorize the effects of climate-induced stresses and the likely mechanisms of resistance and/or factors mitigating these stresses in crop plants. Climate change is a dynamic, multifaceted system of modifications to environmental conditions that include abiotic and biotic factors in the world. Therefore, rapid development of studies on the integration between physiological, biochemical and molecular responses that can admit a systems analysis of plants is important, and knowledge of molecular mechanisms will provide breeding programs with relevance to obtaining cultivars tolerant to abiotic stresses with increased productivity. Under this research topic, reviews, new methods and scientific articles will be selected for publication based on applications to agriculture under climate change. This research topic will cover the following themes: - Adaptive capacity of plants to withstand climate change - The role of biodiversity in sustainable agriculture - Manipulation of microclimate for plant productivity - Role of plant extracts in plant stress mitigation - Phytoremediation and bioremediation factors for crop improvement - Perspective of underutilized crops under climate change - Contribution of plant secondary metabolism to stress tolerance - Plant tissue culture and crop improvement - The role of nanotechnology for climate-resilient agriculture - Pre-breeding and germplasm characterization for the development of agronomically relevant crop traits

Book Description

Plants, unlike animals, are sessile. This demands that adverse changes in their environment are quickly recognized, distinguished and responded to with suitable reactions. Drought, heat, cold and salinity are among the major abiotic stresses that adversely affect plant growth and productivity. In general, abiotic stress often causes a series of morphological, physiological, biochemical and molecular changes that unfavorably affect plant growth, development and productivity. Drought, salinity, extreme temperatures (cold and heat) and oxidative stress are often interrelated; these conditions singularly or in combination induce cellular damage. To cope with abiotic stresses, of paramount significance is to understand plant responses to abiotic stresses that disturb the homeostatic equilibrium at cellular and molecular level in order to identify a common mechanism for multiple stress tolerance. This multi authored edited compilation attempts to put forth an all-inclusive biochemical and molecular picture in a systems approach wherein mechanism and adaptation aspects of abiotic stress are dealt with. The chief objective of the book hence is to deliver state of the art information for comprehending the effects of abiotic stress in plants at the cellular level.

Book Description

Abiotic stress adversely affects crop production worldwide, decreasing average yields for most of the crops to 50%. Among various abiotic stresses affecting agricultural production, drought stress is considered to be the main source of yield reduction around the globe. Due to an increasing world population, drought stress will lead to a serious food shortage by 2050. The situation may become worse due to predicated global climate change that may multiply the frequency and duration and severity of such abiotic stresses. Hence, there is an urgent need to improve our understanding on complex mechanisms of drought stress tolerance and to develop modern varieties that are more resilient to drought stress. Identification of the potential novel genes responsible for drought tolerance in crop plants will contribute to understanding the molecular mechanism of crop responses to drought stress. The discovery of novel genes, the analysis of their expression patterns in response to drought stress, and the determination of their potential functions in drought stress adaptation will provide the basis of effective engineering strategies to enhance crop drought stress tolerance. Although the in-depth water stress tolerance mechanisms is still unclear, it can be to some extent explained on the basis of ion homeostasis mediated by stress adaptation effectors, toxic radical scavenging, osmolyte biosynthesis, water transport, and long distance signaling response coordination. Importantly, complete elucidation of the physiological, biochemical, and molecular mechanisms for drought stress, perception, transduction, and tolerance is still a challenge to the plant biologists. The findings presented in volume 1 call attention to the physiological and biochemical modalities of drought stress that influence crop productivity, whereas volume 2 summarizes our current understanding on the molecular and genetic mechanisms of drought stress resistance in plants.

Book Description

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.

Book Description

Abiotic stresses have become an integral part of crop production. One or other persist either in soil, water or in atmosphere. The information in the areas of injury and tolerant mechanisms, variability for tolerance, breeding and biotechnology for improvement of crop plants against abiotic stresses are lying unorganized in different articles of journals and edited books. This information is presented in this book in organized way with up-to-date citations, which will provide comprehensive literatures of recent advances. More emphasis has been given to elaborate the injury and tolerance mechanisms, and development of improved genotypes against stress environments. This book also deals with the plants' symptoms of particular abiotic stress, reclamation of soil and crop/cropping pattern to over come the effect of adverse condition(s). Each has been laid out with systematic approaches to develop abiotic stress tolerant genotypes using biotechnological tools. Use of molecular markers in stress tolerance and development of transgenic also have been detailed. Air pollution and climate change are the hot topic of the days. Thus, the effect of air pollution and climate change on crop plants have been detailed in the final three s of this book. Under abiotic stress, plant produces a large quantity of free radicals (oxidants), which have been elaborated in a separate 'Oxidative Stress'. This book has been divided into seven major parts- physical stress (salt), water stresses (drought and waterlogging), temperature stresses (heat and cold), metal toxicities (aluminium, iron, cadmium, lead, nickel, chromium, copper, zinc etc) and non-metal toxicities (boron and arsenic), oxidative stress, and finally atmospheric stresses (air pollution, radiation and climate change). Hope, this book will be of greater use for the students and researchers, particularly Plant Breeders and Biotechnologists as well as the Botanists, to understand the injury and tolerance mechanisms, and subsequently improvement of crop genotypes for abiotic stresses.
