This book discusses the recent advancements in the role of various biomolecules in regulating root growth and development. Rhizobiology is a dynamic sub discipline of plant science which collates investigations from various aspects like physiology, biochemistry, genetic analysis and plant–microbe interactions. The physiology and molecular mechanisms of root development have undergone significant advancements in the last couple of decades. Apart from the already known conventional phytohormones (IAA, GA, cytokinin, ethylene and ABA), certain novel biomolecules have been considered as potential growth regulators or hormones regulating plant growth and development. Root phenotyping and plasticity analysis with respect to the specific functional mutants of each biomolecule shall provide substantial information on the molecular pathways of root signaling. Special emphasis provides insights on the tolerance and modulatory mechanisms of root physiology in response to light burst, ROS generation, agravitrophic response, abiotic stress and biotic interactions.

The new edited volume on phytomelatonin and its diverse roles in plants under a challenging environment shall be an important reference book with updated information and future perspectives on the involvement of this biomolecule in stress resilience in plants. Investigations on different aspects of melatonin in plants have undergone a prolific surge in the last decade. In view of such a considerable volume of investigations in melatonin, the proposed new volume will collate its role in different aspects of plants signaling, growth and metabolism. In this context, it has been important to understand its function as a stress priming molecule that executes associative synergistic relation with various other plant growth regulators (viz. nitric oxide, hydrogen sulfide, inorganic ions, and enzymes). Thus, crop management under diverse stressful environments can be better achieved by elucidating our current understanding of the role of melatonin and its interplay with various plant metabolites. The book shall provide a collation of recent advancements in genomic, transcriptomic, and metabolomic approaches to decipher the molecular mechanisms of melatonin signaling and its agronomic importance in plants.

Comprehensive resource detailing the molecular mechanisms underlying heavy metal toxicity and tolerance in plants Heavy Metal Toxicity and Tolerance in Plants provides a comprehensive overview of the physiological, biochemical, and molecular basis of heavy metal tolerance and functional omics that allow for a deeper understanding of using heavy metal tolerance for deliberate manipulation of plants. Through the authors’ unique approach, the text enables researchers to develop strategies to enhance metal toxicity and deficiency tolerance as well as crop productivity under stressful conditions, in order to better utilize natural resources to ensure future food security.

​ To monitor multi-hazards, Remote Sensing and GIS-based multi-criteria decision-making (MCDM) techniques have been extensively used in recent years worldwide. Since natural hazards cannot be eliminated, only quantification of these events and reliable forecasting can alleviate their detrimental effects, through which we can build more resilient and safe societies. Moreover, cultivating the proper knowledge of the multi-hazards and their monitoring and management can fill the gap between science, policy, and the community concerned. In an endeavor to understand and characterize the various hazards, Monitoring and Managing Multi-hazards: A Multidisciplinary approach presents a synthesis of what cross-disciplinary researchers know about these hazards and indigenous adaptation strategies. The book therefore focuses on the use of precision techniques, Remote Sensing, and GIS technologies to quantify various natural, environmental and social hazards along with the capacity building and sustainable mitigation strategies towards resilient societies. It encompasses both thematic and regional case studies to highlight the dynamicity of climate change, change of natural resources, landscape, water, river, agricultural, and social ecosystems at various spatio-temporal scales, including theoretical and applied aspects. The book gives readers an overview and analysis of traditional and advanced geospatial technologies on atmospheric, lithospheric, hydrosphere, biospheric and socio-economic contexts, on all spatial and temporal scales regarding hazards and disasters and sustainable development and management for the future.

Plant neurobiology is a newly emerging field of plant sciences. It covers signalling and communication at all levels of biological organization – from molecules up to ecological communities. In this book, plants are presented as intelligent and social organisms with complex forms of communication and information processing. Authors from diverse backgrounds such as molecular and cellular biology, electrophysiology, as well as ecology treat the most important aspects of plant communication, including the plant immune system, abilities of plants to recognize self, signal transduction, receptors, plant neurotransmitters and plant neurophysiology. Further, plants are able to recognize the identity of herbivores and organize the defence responses accordingly. The similarities in animal and plant neuronal/immune systems are discussed too. All these hidden aspects of plant life and behaviour will stimulate further intense investigations in order to understand the communicative plants in their whole complexity.

This volume provides a collection of protocols aimed toward the study of ethylene signaling in plants. Ethylene Signaling: Methods and Protocols is divided into three sections: ethylene biosynthesis, the signal transduction pathway, and the diverse ethylene responses of dicots and monocots. The chapters in section one discuss techniques for the measurement of activities related to the biosynthetic enzymes ACC synthase and ACC oxidase, the levels of ethylene synthesized by plants, and the treatment of plants with exogenous ethylene. Section two focuses on the analysis of the new membrane-associated proteins involved in the initial perception and transduction of the ethylene signal, such as ethylene receptors, CTR1, and EIN2. The third section covers assays applicable to dicots and monocots, including methods related to the roles of ethylene in germination, growth, abscission, abiotic stress, and defense. Section three also includes information on Arabidopsis mutants and the variety of chemical inhibitors that affect ethylene responses. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Thorough and comprehensive, Ethylene Signaling: Methods and Protocols is a valuable resource for both experienced and beginner researchers with prior experience in the study of ethylene signaling and for those who are just entering this exciting research field.
