Neurotransmitters in Plant Signaling and Communication


Book Description

This book provides a comprehensive update on the recent developments concerning the role of plant neurotransmitters in signaling and communication. Physiological investigations over the past few decades have demonstrated that plants employ neurotransmitters in various signaling pathways. Plant-based neurotransmitters (serotonin, melatonin, dopamine, acetylcholine, and GABA) share biochemical similarities with those in animal systems in terms of their chemical nature and biochemical pathways. Plant–environment interaction associated with abiotic stress management, growth modulation, flowering, circadian rhythm, fruit ripening, and allelopathic interactions are a major focus of research in the field, and recent advances in genomic, trascriptomic, and metabolomic approaches have resulted in the deciphering of the molecular mechanisms associated with various neurotransmitters in plants. Other current and potential areas of investigation include the putative phytohormone phytomelatonin, and receptor-mediated signaling in plant neurotransmitters. Providing an up-to-date overview of molecular crosstalk mechanisms between various neurotransmitters, the book offers essential insights to help readers gain a better understanding of the physiology of plant signaling and communication with the environment.




Protective Chemical Agents in the Amelioration of Plant Abiotic Stress


Book Description

A guide to the chemical agents that protect plants from various environmental stressors Protective Chemical Agents in the Amelioration of Plant Abiotic Stress offers a guide to the diverse chemical agents that have the potential to mitigate different forms of abiotic stresses in plants. Edited by two experts on the topic, the book explores the role of novel chemicals and shows how using such unique chemical agents can tackle the oxidative damages caused by environmental stresses. Exogenous application of different chemical agents or chemical priming of seeds presents opportunities for crop stress management. The use of chemical compounds as protective agents has been found to improve plant tolerance significantly in various crop and non-crop species against a range of different individually applied abiotic stresses by regulating the endogenous levels of the protective agents within plants. This important book: Explores the efficacy of various chemical agents to eliminate abiotic stress Offers a groundbreaking look at the topic and reviews the most recent advances in the field Includes information from noted authorities on the subject Promises to benefit agriculture under stress conditions at the ground level Written for researchers, academicians, and scientists, Protective Chemical Agents in the Amelioration of Plant Abiotic Stress details the wide range of protective chemical agents, their applications, and their intricate biochemical and molecular mechanism of action within the plant systems during adverse situations.




Phytohormones and Abiotic Stress Tolerance in Plants


Book Description

Plants are sessile and prone to multiple stresses in the changing environmental conditions. Of the several strategies adopted by plants to counteract the adverse effects of abiotic stress, phytohormones provide signals to allow plants to survive under stress conditions. They are one of the key systems integrating metabolic and developmental events in the whole plant and the response of plants to external factors and are essential for many processes throughout the life of a plant and influence the yield and quality of crops. The book ‘Phytohormones and Abiotic Stress Tolerance in Plants’ summarizes the current body of knowledge on crosstalk between plant stresses under the influence of phytohormones, and provides state-of-the-art knowledge of recent developments in understanding the role of phytohormones and abiotic stress tolerance in plants. This book presents information on how modulation in phytohormone levels affect regulation of biochemical and molecular mechanisms.

Abiotic and Biotic Stress in Plants


Book Description

Plants are subjected to numerous environmental stresses, which can be classified into two broad areas: abiotic and biotic stresses. While the first is considered the damage done to an organism by other living organisms, the latter occurs as a result of a negative impact of non-living factors on the organisms. In this scenario, the current most accepted opinion of scientists is that both biotic and abiotic factors in nature and agroecosystems are affected by climate change, which may lead to significant crop yield decreases worldwide. We should take into consideration not only this environmental concern but also the fact that 20 years from now the earth's population will need 55% more food than it can produce now. Therefore, it is crucial to address such concerns and bring about possible solutions to future plant stress-related outcomes that might affect global agriculture. This book intends to provide the reader with a comprehensive overview of both biotic and abiotic stresses through 10 chapters that include case studies and literature reviews about these topics. There will be a particular focus on understanding the physiological, biochemical, and molecular changes observed in stressed plants as well as the mechanisms underlying stress tolerance in plants.
