This edited book deals with the distribution, classification and diversity of halophytic ecosystems, ecology of mangroves, coastal agroforestry, adaptations and mechanisms of salt tolerance in glycophytes verses halophytes, scope of biosaline agriculture, and potential utilization of halophytes in abiotic stressed environments in arid and semiarid regions and coastal areas. In this era of global population increase and global environmental change, there is need to provide food to the ever-growing population, combating climate change and conserving biodiversity. Keeping in view the rich biodiversity of halophytes, there is wide scope in food industry, phytoremediation, as well as a source of bioactive compounds including modern drugs. The new technologies for the cultivation of halophytes help to utilize saline and arid wastelands and also waterlogged areas sustainably for humans and the livestock. This book creates interest in educationists, researchers, industrialists, investors, soil and climate change scientists, development/extension workers, environmentalists, policy/decision makers, and government and non-government organizations. Also, the book serves as reference material for undergraduate and graduate students of agriculture, ecology, soil science, and environmental sciences. National and international soil and agricultural scientists, ecologists, policy makers will also find this book immensely useful.

Facing stressful conditions imposed by their environment and affecting their growth and their development throughout their life cycle, plants must be able to perceive, to process and to translate different stimuli into adaptive responses. Understanding the organism-coordinated responses involves a fine description of the mechanisms occurring at the cellular and molecular level. A major challenge is also to understand how the large diversity of molecules identified as signals, sensors or effectors could drive a cell to the appropriate plant response and to finally cope with various environmental cues. In this Research Topic we aim to provide an overview of various signaling mechanisms or to present new molecular signals involved in stress response and to demonstrate how basic/fundamental research on cell signaling will help to understand stress responses at the whole plant level.

This contributed volume covers a comprehensive account of the sources, toxic biological as well as environmental impacts, and possible remediation strategies for contamination by heavy metals. In biological systems, toxic metals affect the integrity of cellular organelles and act as carcinogens causing chromosomal aberrations or as systemic toxicants leading to cardiovascular, neurobehavioral, and immunological disorders. In plants, they interfere with photosynthesis, fertility, metabolite, and chlorophyll synthesis. Toxicity induced by heavy metals involves mechanistic approaches that need to be understood properly. They cannot be degraded by biological or chemical means and thus can only be converted to less harmful forms. The conventional detection methods include biosensors, voltammetry, atomic absorption spectrometry, and inductively coupled plasma with atomic emission spectrometry. All such strategies for metal detection and mitigation strategies are covered in this title under one section. This book incorporates classical views along with modern scientific approaches to develop an understanding of the subject matter suitable for academicians, researchers, planners, policymakers, NGOs, and environmental consultancies and raise awareness on this concern. Topics representing diverse sections namely environmental impacts, biological effects, and methods used for detection and remediation have been included to address all possible contemporary issues on the topic in one concise volume.

Salinity is one of the major environmental constraints that affect many regions of the globe, and its rate of expansion is expected to increase. The interest in phytoremediation of salt-rich and contaminated soils and water has been increased in recent years, but several aspects about the plants’ responses to salinity still need to be clarified. Guayule (Parthenium argentatum Gray) and castor bean (Ricinus communis L.) are among the plant species considered for growing in saline environments. This study aims to investigate the responses of guayule and castor to high concentrations of sodium chloride (NaCl), and the recovery capacity of castor plants. To meet these purposes, hydroponically grown guayule and castor plants were exposed to increasing NaCl concentrations. Growth parameters (morphological determinations and biomass production), physiological parameters (chlorophyll fluorescence, gas exchanges and photosynthetic pigments) and chemical analyses (sodium and mineral nutrient tissue-contents) were evaluated. The typical symptoms of salt-stress were observed in the two species, with differences in their responses to osmotic and ionic-specific stress components. Variations in growth and physiological parameters indicate that guayule and castor showed symptoms of ionic stress when exposed to concentrations of NaCl around 15 g L-1 and 10 g L-1 respectively. Guayule and castor did not survive at hypersaline conditions (above 35 g L-1 NaCl), but they survived at high saline conditions (above 5 g L-1 NaCl), indicating that the two species are suitable to be grown in saline soils and wetlands.

This book provides a practical guidance and a set of principles for improving management of saline and alkali waters and thus would be useful for different stakeholders, including agricultural students, researchers, environmentalists, and policy makers. The worldwide aggregated area with occurrence of saline and brackish groundwater is about 24 million square kilometers causing annual food losses to the extent of food requirements of 170 million people. For fostering the safe and reliable use of these waters, researchers have innovated management techniques helping sustainable irrigation with waters otherwise rated earlier as unfit. Vast pool of information has been put together in this book covering groundwater irrigation scenario and need for non-conventional waters; extent, genesis, and global distribution of saline groundwater; impacts of saline and alkali irrigation waters on soils and crops; management approaches for sustaining irrigation with typical saline and alkali ground waters for agricultural and horticulture crops; steady and non-steady state models for salt and water dynamics vis-a-vis crop responses; alternate uses of highly saline waters; water quality guidelines for irrigation under different soil and agro-climatic conditions and ultimately some researchable and policy issues for promoting irrigation with these waters.

The gaseous molecule ethylene (C2H4), which is small in size and simple in structure, is a plant hormone most often associated with fruit ripening yet has a diversity of effects throughout the plant life cycle. While its agricultural effects were known even in ancient Egypt, the complexity of its mode of action and the broad spectrum of its effects and potential uses in plant physiology remain important scientific challenges today. In the last few decades, the biochemical pathway of ethylene production has been uncovered, ethylene perception and signaling have been molecularly dissected, ethylene-responsive transcription factors have been identified and numerous effects of ethylene have been described, ranging from water stress, development, senescence, reproduction plant-pathogen interactions, and of course, ripening. Thus ethylene is involved in plant development, in biotic and abiotic stress, and in reproduction. There is no stage in plant life that is not affected by ethylene, modulated by a complex and fascinating molecular machinery.
