The book provides an overview of water stress in plants and alterations in the physiology, morphology, anatomy, and molecular mechanism due to water stress. The induction of water stress hormones and the up-regulating genes synthesizing them is also the major thrust of the book. It also deals with the water and nutrient uptake, alteration in water relations, transpiration and stomatal conductance, and hence in the amount of photosynthesis vis-à-vis water stress. It compiles recent studies on redox regulation, antioxidative systems, nitrogen metabolism and phytohormonal regulation in crop plants during water stress. Different strategies to manage water stress, viz. by using different osmolytes, proteins, hormones and growth regulators, antioxidants, plant extracts, nitric oxide donors, macro and micro mineral nutrients, and the use of silicon have been discussed. The viability of different biotechnological tools to make crop plants less water-demanding, the use of vetiver grass and the insertion of mycorrhiza in water-stressed crop plants have been explored. An exhaustive review of recent literature encompassing genomic, proteomic, transcriptomic, ionomics, and metabolomics approaches to have a better understanding of water stress is the prominent feature of the present book. It discusses major signaling molecules involved in water-stressed environments as well as the crosstalk with other minerals, phytohormones etc. Not least, the book endeavors to illustrate different water conservation methods to achieve sustainable agriculture. The book is a comprehensive compilation of work to date on water stress and its management techniques and this will bridge the missing gap between the research from the past to the current time.

Ultraviolet-B (UV-B) is electromagnetic radiation coming from the sun, with a medium wavelength which is mostly absorbed by the ozone layer. The biological effects of UV-B are greater than simple heating effects, and many practical applications of UV-B radiation derive from its interactions with organic molecules. It is considered particularly harmful to the environment and living things, but what have scientific studies actually shown?UV-B Radiation: From Environmental Stressor to Regulator of Plant Growth presents a comprehensive overview of the origins, current state, and future horizons of scientific research on ultraviolet-B radiation and its perception in plants. Chapters explore all facets of UV-B research, including the basics of how UV-B's shorter wavelength radiation from the sun reaches the Earth's surface, along with its impact on the environment's biotic components and on human biological systems. Chapters also address the dramatic shift in UV-B research in recent years, reflecting emerging technologies, showing how historic research which focused exclusively on the harmful environmental effects of UV-B radiation has now given way to studies on potential benefits to humans. Topics include: UV-B and its climatologyUV-B and terrestrial ecosystemsPlant responses to UV-B stressUB- B avoidance mechanismsUV-B and production of secondary metabolitesDiscovery of UVR8Timely and important, UV-B Radiation: From Environmental Stressor to Regulator of Plant Growth is an invaluable resource for environmentalists, researchers and students who are into the state-of-the-art research being done on exposure to UV-B radiation.

Arsenic in Plants Comprehensive resource detailing the chemistry, toxicity and impact of arsenic in plants, and solutions to the problem Arsenic in Plants: Uptake, Consequences and Remediation Techniques provides comprehensive coverage of the subject, detailing arsenic in our environment, the usage of arsenicals in crop fields, phytotoxicity of arsenic and arsenic’s impact on the morphology, anatomy and quantitative and qualitative traits of different plant groups, including their physiology and biochemistry. The work emphasizes the occurrence of arsenic, its speciation and transportation in plants, and differences in mechanisms of tolerance in hyper-accumulator and non-accumulator plants. Throughout the text, the highly qualified authors delve into every facet of the interaction of arsenic with plants, including the ionomics, genomics, transcriptomics and proteomics in relation to arsenic toxicity, impact of exogenous phytohormones and growth-regulating substances, management of arsenic contamination in the soil-plant continuum, phytoremediation of arsenic toxicity and physical removal of arsenic from water. General discussion has also been included on subjects such as the ways through which this metalloid affects plant and human systems. Topics covered include: Introduction and historical background of arsenic and the mechanism of arsenic transport and metabolism in plantsArsenic-induced responses in plants, including impact on biochemical processes and different plant groups, from cyanobacteria to higher plantsThe role of phytohormones, mineral nutrients, metabolites and signaling molecules in regulating arsenic-induced toxicity in plantsGenomic, proteomic, metabolomic, ionomic and transcriptional regulation during arsenic stressStrategies to reduce the arsenic contamination in soil-plant systems and arsenic removal by phytoremediation techniquesResearchers, academics, and students of plant physiology, biotechnology, and agriculture will find valuable information in Arsenic in Plants to understand this pressing subject in full, along with its implications and how we can adapt our strategies and behaviors to promote reduced contamination through practical applications.
