Book excerpt: Halophytes are a fascinating group of wild plants adapted to highly saline natural habitats, where most plant species and all our conventional crops would not survive. In fact, some halophytes can withstand even seawater salinity. In the current climate change scenario, increasing average temperatures and drought episodes contribute to the accelerated salinisation of irrigated cropland, especially in arid and semiarid regions, by the progressive accumulation in the soil of salts dissolved in irrigation water. This 'secondary salinisation' is one of the major causes of reducing crop yields worldwide. In this context, halophytes represent ideal experimental systems to investigate the mechanisms plants use to respond to high-salinity conditions. This knowledge will be essential for the genetic improvement of crop salt tolerance, which represents the most sensible strategy to address the abovementioned problem. Furthermore, halophytes could be the basis of a sustainable, 'saline' agriculture, after domestication and some breeding to improve agronomic characteristics. Then, they could be commercially cultivated for food, feed, fibre, or the production of biomolecules of industrial interest. Since they could be grown in saline land and irrigated with brackish water, they will not compete with our conventional crops for these limited resources, fertile land and good-quality water for irrigation. The articles included in this Special Issue address these different aspects of halophytes' research, although most focus on basic studies on salt-tolerance mechanisms.

Available in PDF, EPUB and Kindle. Book excerpt: 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. ​​

Book excerpt: Soil salinity is destroying several hectares of arable land every minute. Because remedial land management cannot completely solve the problem, salt tolerant crops or plant species able to remove excessive salt from the soil could contribute significantly to managing the salinity problem. The key to engineering crops for salt tolerance lies in a thorough understanding of the physiological mechanisms underlying the adaptive responses of plants to salinity. Plant Salt Tolerance: Methods and Protocols describes recent advances and techniques employed by researchers to understand the molecular and ionic basis of salinity tolerance and to investigate the mechanisms of salt stress perception and signalling in plants. With chapters written by leading international scientists, this book covers nearly 30 different methods, such as microelectrode and molecular methods, imaging techniques, as well as various biochemical assays. Written in the highly successful Methods in Molecular BiologyTM series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Plant Salt Tolerance: Methods and Protocols serves as an essential read for every student or researcher tackling various aspects of the salinity problem.

Download or read book Salinity Responses and Tolerance in Plants Volume 1 written by Vinay Kumar and published by Springer. This book was released on 2018-04-05 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2011-03-01 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salinity tolerance in plants is a complex problem encompassing numerous morphological, physiological and biochemical processes and adaptations at the cellular, sub-cellular and whole plant levels. The book comprising eleven chapters deals with diverse aspects of salt tolerance including plant response to salinity and sodicity, crop tolerance at different growth stages and criteria for evaluating the same. The mechanism of salt injury viz. osmotic, ionic and nutrient imbalance has been dealt with, adopting an integrated appraoch. Likewise, the recent information on photosynthesis, respiration, carbohydrate, nitrogen and protein metabolism, enzyme dynamics and plant hormones, as well as nodulation and symbiotic nitrogen fixation in legumes has been elaborated comprehensively. Special attention has been given to the interaction between essential nutrients and salinity as it is vital for alleviation of adverse effects of salt stress. The synthesis of knowledge on different mechanisms of salt resistance, including osmoregulation with organic and inorganic solutes has also been presented. Various methods of introducing salt tolerance in plants such as breeding, genetic variations, physiological approaches, tissue culture, somaclonal variation, somatic hybridation and recombinat DNA technology have been discussed. The nature and properties of salt affected soils and groundwaters and principles for amelioration and management of these critical problems have been included in this book. Furthermore, Afforestation and Agroforestry techniques for salt affected soils with emphasis on salt tolerant tree species and suitable tree crop combinations also find their much needed due space in the present book.

Available in PDF, EPUB and Kindle. Book excerpt: Abiotic stresses such as high temperature, low-temperature, drought, and salinity limit crop productivity worldwide. Understanding plant responses to these stresses is essential for rational engineering of crop plants. In Arabidopsis, the signal transduction pathways for abiotic stresses, light, several phytohormones and pathogenesis have been elucidated. A significant portion of plant genomes (most studies are Arabidopsis and rice genome) encodes for proteins involves in signaling such as receptor, sensors, kinases, phosphatases, transcription factors and transporters/channels. Despite decades of physiological and molecular effort, knowledge pertaining to how plants sense and transduce low and high temperature, low-water availability (drought), water-submergence and salinity signals is still a major question before plant biologists. One major constraint hampering our understanding of these signal transduction processes in plants has been the lack or slow pace of application of molecular genomic and genetics knowledge in the form of gene function. In the post-genomic era, one of the major challenges is investigation and understanding of multiple genes and gene families regulating a particular physiological and developmental aspect of plant life cycle. One of the important physiological processes is regulation of stress response, which leads to adaptation or adjustment in response to adverse stimuli. With the holistic understanding of the signaling pathways involving not only one gene family but multiple genes or gene families, plant biologists can lay a foundation for designing and generating future crops that can withstand the higher degree of environmental stresses (especially abiotic stresses, which are the major cause of crop loss throughout the world) without losing crop yield and productivity. Therefore, in this proposed book, we intend to incorporate the contribution from leading plant biologists to elucidate several aspects of stress signaling by functional genomic approaches.

Download or read book Salinity Tolerance in Plants Mechanisms and Regulation of Ion Transport written by Vadim Volkov and published by Frontiers Media SA. This book was released on 2018-01-12 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: A. POLJAKOFF-MAYBER and J. GALE The response of plants to saline environments is of interest to people of many disciplines. In agriculture the problem of salinity becomes more severe every year as the non-saline soils and the non-saline waters become more intensively and more extensively exploited. Further expansion of agriculture must consider the cultivation of saline soils and the use of water with a relatively high content of soluble, salts. Moreover, industrial development in many countries is causing severe water pollution, especially of rivers, and mismanagement in agriculture often induces secondary salinization of soils and sources of irrigation water. From the point of view of agriculture it is, therefore, of the utmost importance to know the various responses of plants to salinity and to understand the nature of the damage caused by salinity to agricultural crops. Botanists and plant physiologists study plants, their form, growth, metabolism and response to external stimuli. A challenging problem for them is to understand the differences between glycophytes, plants growing in a non-saline environment and halophytes, plants which normally grow in salt marshes, in sea water or in saline soils. This includes the elucidation of structural and functional adaptations which enable halophytes to tolerate the saline environment, and also questions as to whether they only tolerate the saline environment or actually thrive in it. Ecologists and environmentalists are interested in the interrelationships be tween the organism, in this case the plant, and its environment, from the climatic, edaphic and biotic points of view.

Download or read book Salinity Environment Plants Molecules written by André Läuchli and published by Springer Science & Business Media. This book was released on 2002-03-31 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the responses of plants to salinity. Although salinity is a common environmental factor for marine organisms, for the majority of land plants high soil salinity is an environmental constraint that limits growth, productivity, and normal plant functions. Salinity is particularly widespread in arid/semiarid climates where crop production depends on irrigation. A comprehensive approach is taken in this book. After discussing salinity as an environmental soil factor and its global impact on ecosystems, plant responses are covered from the whole-plant level through metabolic changes to the underlying molecular and genetic mechanisms. In contrast to other books in this subject area, which focus on certain aspects of plant responses to salinity or are conference proceedings, this is the only comprehensive new book on this subject, written by experts in the field. The intended level of readership is graduate students and advanced researchers interested in environmental biology and specifically in the area of mechanisms of environment-plant interactions.

Download or read book Mechanisms of Salt Tolerance in the Halophyte Seashore Paspalum written by John James Spiekerman and published by . This book was released on 2019 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the coming decades, crop production will need to increase to meet the demands of a burgeoning population. Moreover, climate change-induced drought is predicted to increase irrigation, and in turn, soil salinity. About 20% of irrigated land worldwide is considered saline without any efficient means of removing salt from the soil. Saline soils significantly inhibit plant growth, and thus salt tolerant crops are needed to continue food production in the future. Most salt tolerance research has focused on salt-sensitive glycophytes, including most crop species we rely on. Research on tolerance mechanisms in halophytes, plant species that thrive in salt, is currently limited. We have chosen seashore paspalum (Paspalum vaginatum), a halophytic grass closely related to agronomically vital crops in the Panicoideae, to better under mechanisms of salt tolerance in halophytes. Seashore paspalum is used as a popular turfgrass due to its ability to be irrigated with brackish water, stemming from its high salt tolerance. Though it has been intensely studied, it has only been done so as a turf. We have grown seashore paspalum in a novel way, without trimming plants, to gain a more accurate understanding of how it copes with elevated salinity. This has been done in comparison with P. distichum, a glycophytic sister species that inhabits mostly freshwater habitats. We show that Paspalum is tolerant of salt shock conditions and show that genotypes that are slow-growing under low salt lose less relative biomass under high salt. Furthermore, we provide evidence for a novel mechanism of sodium sequestration in seashore paspalum, whereby sodium is sequestered in leaf papillae, the first known specialized organ for sodium sequestration in the Panicoideae. An RNA-seq analysis further illustrates differences between seashore paspalum accession 0́HI10' and P. distichum accession 0́8Spence', with 0́8HI10' being poised to respond to salt stress, while many mechanisms are salt induced in 0́8Spence'. Collectively, our results lay the groundwork for investigating seashore paspalum as a model halophytic system.

Download or read book Salinity Tolerance in Plants written by Jose Antonio Hernández Cortés and published by MDPI. This book was released on 2019-06-12 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salt stress is one of the most damaging abiotic stresses because most crop plants are susceptible to salinity to different degrees. According to the FAO, about 800 million Has of land are affected by salinity worldwide. Unfortunately, this situation will worsen in the context of climate change, where there will be an overall increase in temperature and a decrease in average annual rainfall worldwide. This Special Issue presents different research works and reviews on the response of plants to salinity, focused from different points of view: physiological, biochemical, and molecular levels. Although an important part of the studies on the response to salinity have been carried out with Arabidopsis plants, the use of other species with agronomic interest is also notable, including woody plants. Most of the conducted studies in this Special Issue were focused on the identification and characterization of candidate genes for salt tolerance in higher plants. This identification would provide valuable information about the molecular and genetic mechanisms involved in the salt tolerance response, and it also supplies important resources to breeding programs for salt tolerance in plants.
