Salinity Tolerance in Plants: Mechanisms and Regulation of Ion Transport by Vadim Volkov,Mary J. Beilby Pdf

Life presumably arose in the primeval oceans with similar or even greater salinity than the present ocean, so the ancient cells were designed to withstand salinity. However, the immediate ancestors of land plants most likely lived in fresh, or slightly brackish, water. The fresh/brackish water origins might explain why many land plants, including some cereals, can withstand moderate salinity, but only 1 – 2 % of all the higher plant species were able to re-discover their saline origins again and survive at increased salinities close to that of seawater. From a practical side, salinity is among the major threats to agriculture, having been one of the reasons for the demise of the ancient Mesopotamian Sumer civilisation and in the present time causing huge annual economic losses of over 10 billion USD. The effects of salinity on plants include osmotic stress, disruption of membrane ion transport, direct toxicity of high cytoplasmic concentrations of sodium and chloride on cellular processes and induced oxidative stress. Ion transport is the crucial starting point that determines salinity tolerance in plants. Transport via membranes is mediated mostly by the ion channels and transporters, which ensure selective passage of specific ions. The molecular and structural diversity of these ion channels and transporters is amazing. Obtaining the detailed descriptions of distinct ion channels and transporters present in halophytes, marine algae and salt-tolerant fungi and then progressing to the cellular and the whole organism mechanisms, is one of the logical ways to understand high salinity tolerance. Transfer of the genes from halophytes to agricultural crops is a means to increase salt tolerance of the crops. The theoretical scientific approaches involve protein chemistry, structure-function relations of membrane proteins, synthetic biology, systems biology and physiology of stress and ion homeostasis. At the time of compiling this e-book many aspects of ion transport under salinity stress are not yet well understood. The e-book has attracted researchers in ion transport and salinity tolerance. We have combined our efforts to achieve a wider, more detailed understanding of salt tolerance in plants mediated by ion transport, to understand present and future ways to modify and manipulate ion transport and salinity tolerance and also to find natural limits for the modifications.

Salinity Responses and Tolerance in Plants, Volume 1 by Vinay Kumar,Shabir Hussain Wani,Penna Suprasanna,Lam-Son Phan Tran Pdf

Soil salinity is a key abiotic-stress and poses serious threats to crop yields and quality of produce. Owing to the underlying complexity, conventional breeding programs have met with limited success. Even genetic engineering approaches, via transferring/overexpressing a single ‘direct action gene’ per event did not yield optimal results. Nevertheless, the biotechnological advents in last decade coupled with the availability of genomic sequences of major crops and model plants have opened new vistas for understanding salinity-responses and improving salinity tolerance in important glycophytic crops. Our goal is to summarize these findings for those who wish to understand and target the molecular mechanisms for producing salt-tolerant and high-yielding crops. Through this 2-volume book series, we critically assess the potential venues for imparting salt stress tolerance to major crops in the post-genomic era. Accordingly, perspectives on improving crop salinity tolerance by targeting the sensory, ion-transport and signaling mechanisms are presented here in volume 1. Volume 2 will focus on the potency of post-genomic era tools that include RNAi, genomic intervention, genome editing and systems biology approaches for producing salt tolerant crops.

Abiotic Stress in Plants by Arun Shanker,B. Venkateswarlu Pdf

World population is growing at an alarming rate and is anticipated to reach about six billion by the end of year 2050. On the other hand, agricultural productivity is not increasing at a required rate to keep up with the food demand. The reasons for this are water shortages, depleting soil fertility and mainly various abiotic stresses. The fast pace at which developments and novel findings that are recently taking place in the cutting edge areas of molecular biology and basic genetics, have reinforced and augmented the efficiency of science outputs in dealing with plant abiotic stresses. In depth understanding of the stresses and their effects on plants is of paramount importance to evolve effective strategies to counter them. This book is broadly dived into sections on the stresses, their mechanisms and tolerance, genetics and adaptation, and focuses on the mechanic aspects in addition to touching some adaptation features. The chief objective of the book hence is to deliver state of the art information for comprehending the nature of abiotic stress in plants. We attempted here to present a judicious mixture of outlooks in order to interest workers in all areas of plant sciences.

Salt Stress in Plants by Parvaiz Ahmad,M.M. Azooz,M.N.V. Prasad Pdf

Environmental conditions and changes, irrespective of source, cause a variety of stresses, one of the most prevalent of which is salt stress. Excess amount of salt in the soil adversely affects plant growth and development, and impairs production. Nearly 20% of the world’s cultivated area and nearly half of the world’s irrigated lands are affected by salinity. Processes such as seed germination, seedling growth and vigour, vegetative growth, flowering and fruit set are adversely affected by high salt concentration, ultimately causing diminished economic yield and also quality of produce. Most plants cannot tolerate salt-stress. High salt concentrations decrease the osmotic potential of soil solution, creating a water stress in plants and severe ion toxicity. The interactions of salts with mineral nutrition may result in nutrient imbalances and deficiencies. The consequence of all these can ultimately lead to plant death as a result of growth arrest and molecular damage. To achieve salt-tolerance, the foremost task is either to prevent or alleviate the damage, or to re-establish homeostatic conditions in the new stressful environment. Barring a few exceptions, the conventional breeding techniques have been unsuccessful in transferring the salt-tolerance trait to the target species. A host of genes encoding different structural and regulatory proteins have been used over the past 5–6 years for the development of a range of abiotic stress-tolerant plants. It has been shown that using regulatory genes is a more effective approach for developing stress-tolerant plants. Thus, understanding the molecular basis will be helpful in developing selection strategies for improving salinity tolerance. This book will shed light on the effect of salt stress on plants development, proteomics, genomics, genetic engineering, and plant adaptations, among other topics. The book will cover around 25 chapters with contributors from all over the world. ​​

Handbook of Plant Salinity Tolerance by Walker Williams Pdf

Plants are exposed to a number of biotic and abiotic stresses. Soil salinity is one of the major abiotic stresses, which negatively affects plant growth and crop production. Stress due to salinity leads to various changes in the physiological and metabolic processes based on the severity and duration of the stress. In the initial stages, soil salinity leads to osmotic stress, which causes physiological changes such as nutrient imbalance, interruption of membranes, decreased photosynthetic activity, and inhibition of the ability to detoxify the reactive oxygen species. In the later stage, soil salinity leads to ionic toxicity that leads to nutrient imbalance in the cytosol. In order to overcome salinity stress, plants have developed several mechanisms such as ion homeostasis and compartmentalization, ion transport and uptake, generation of nitric oxide (NO), and synthesis of polyamines. This book includes some of the vital pieces of works being conducted across the world on various topics related to plant salinity tolerance. It will help the readers in keeping pace with the rapid changes in this area of study.

Salt Stress Responses in Plants by Prabhat Kumar Srivastava,Jitendra Kumar (Environmental scientist),Sheo Mohan Prasad Pdf

"Intense farming and irrigation practices are the important causes of salinity which limit plant growth and productivity. Salinity has now impacted 6 % of the total and 33 % of the irrigated land. The severest salinity problem has arisen in semiarid or arid lands when they were subjected to excessive irrigation which turned hundreds of hectares of cultivated fertile lands into saline lands. When a change in salinity around the environment of a plant exceeds to a certain threshold level, the morphology and physiology of the plants are affected. This book emphasizes the menace of salinity in agriculture and crop production. It encompasses various studies on plants sensitive to salt (glycophytes) and tolerant to salt (halophytes). This book includes diversity of glycophytes and halophytes, effects of salinity on different stages of growth and development, ion homeostasis and cellular ion transport, their photosynthetic responses, effects on biological nitrogen fixation, redox regulation and phytohormonal adjustment, significance of mineral nutrients in combating salinity in food crops. The most significant feature of the present book is its extensive coverage of genomics, metabolomics, ionomics, proteomics and transcriptomics approach which provide a better understanding towards salt and its interaction with plants. This book is beneficial for the students of stress physiology, environmental sciences, agronomy, life sciences and crop sciences at university level"--

Ion Channels and Plant Stress Responses by Vadim Demidchik,Frans J.M. Maathuis Pdf

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 ef?cacy of such mechanisms underlies the plant performance during stress and therefore also impacts greatly on agricultural productivity. M- ulation of ion channel activity not only provides a means for rapid signal generation 2+ but also allows adjustment of cellular physiology. For example, Ca permeable ion 2+ channels can transduce environmental stimuli into Ca -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 de?ciency, 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 endogenous signals during stress and as mechanisms to regulate cellular ion homeostasis and enzymatic activities in the context of biotic and abiotic stress. The chapters presented cover cation and anion channels located in various cellular compartments and tissues.

Salinity Responses and Tolerance in Plants: Transport and Signaling Mechanisms by Simon Vader Pdf

Plants need to adapt to a variety of environmental conditions such as salinity, drought, light and temperature which affect their growth, flowering and fruiting. Plant cells communicate with each other in order to respond to changing external environment. Soil salinity is one of the major abiotic stresses which affect the plant growth. It induces cytotoxicity due to excessive uptake of sodium and chloride ions. Salinity is also accompanied by oxidative stress. It can be induced due to poor quality of water for irrigation and soil salinization. Some of the tolerance mechanisms adopted by plants are ion homeostasis, hormone modulation, synthesis of polyamines, compartmentalization, and activation of antioxidant enzymes. The book aims to shed light on some of the unexplored aspects of salinity response and tolerance in plants and the recent researches in this field. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included herein. This book is a vital tool for all researching or studying salinity response and tolerance in plants as it gives incredible insights into emerging trends and concepts.

Plants, Stress & Proteins by Dipanjana Ghosh,Qingsong Lin,Jian Xu,Hanjo A. Hellmann Pdf

Biotic and abiotic stress factors deliver a huge impact on plant life. Biotic stress factors such as damage through pathogens or herbivore attack, as well as abiotic stress factors like variation in temperature, rainfall and salinity, have placed the plant kingdom under constant challenges for survival. As a consequence, global agricultural and horticultural productivity has been disturbed to a large extent. Being sessile in nature, plants cannot escape from the stress, and instead adapt changes within their system to overcome the adverse conditions. These changes include physiological, developmental and biochemical alterations within the plant body which influences the genome, proteome and metabolome profiles of the plant. Since proteins are the ultimate players of cellular behavior, proteome level alterations during and recovery period of stress provide direct implications of plant responses towards stress factors. With current advancement of modern high-throughput technologies, much research has been carried out in this field. This e-book highlights the research and review articles that cover proteome level changes during the course or recovery period of various stress factors in plant life. Overall, the chapters in this e-book has provided a wealth of information on how plants deal with stress from a proteomics perspective.
