Intense farming and irrigation practices are 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, and 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 provides a better understanding towards salt and its interaction with plants. This book is beneficial for students of stress physiology, environmental sciences, agronomy, life sciences and crop sciences at the university level.

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 plants Arsenic-induced responses in plants, including impact on biochemical processes and different plant groups, from cyanobacteria to higher plants The role of phytohormones, mineral nutrients, metabolites and signaling molecules in regulating arsenic-induced toxicity in plants Genomic, proteomic, metabolomic, ionomic and transcriptional regulation during arsenic stress Strategies to reduce the arsenic contamination in soil-plant systems and arsenic removal by phytoremediation techniques Researchers, 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.

A guide to the diversity of pesticides used in modern agricultural practices, and the relevant social and environmental issues Pesticides in Crop Production offers an important resource that explores pesticide action in plants; pesticide metabolism in soil microbes, plants and animals; bioaccumulation of pesticides and sensitiveness of microbiome towards pesticides. The authors explore pesticide risk assessment, the development of pesticide resistance in pests, microbial remediation of pesticide intoxicated legumes and pesticide toxicity amelioration in plants by plant hormones. The authors include information on eco-friendly pest management. They review the impact of pesticides on soil microorganism, crops and other plants along with the impact on other organisms like aquatic fauna and terrestrial animals including human beings. The book also contains an analysis of pesticide by GC-MS/MS (Gas Chromatography tandem Mass Spectrometry) a reliable method for the quantification and confirmation of multiclass pesticide residues. This important book: Offers a comprehensive guide to the use of the diversity of pesticides and the pertinent social and environmental issues Explores the impact of pesticides from morphological, anatomical, physiological and biochemical perspectives Shows how pesticides affects soil microorganisms, crops and other plants along with the impact on other organisms like aquatic fauna and animals Critically examines whether chemical pesticides are boon or bane and whether they can be replaced by environmental friendly pesticides Written for students, researchers and professionals in agriculture, botany, entomology and biotechnology, Pesticides in Crop Production examines the effects of chemical pesticides and the feasibility of using bio-pesticides.
