Nowadays, due to the environmental stress factors that limit the production of crops, it has become very difficult to find suitable areas to enable the plant to reach its optimum product potential. Abiotic stress is very effective in decreasing agricultural production. Factors such as drought, salinity, high and low temperature, flood, radiation, heavy metals, oxidative stress, and nutrient deficiency can be considered as abiotic stress factors, and these sources of stress negatively affect plant growth, quality and productivity. Melatonin (MEL) was first identified in plants in 1995 and is increasingly becoming important for its role and effects in the plant system. MEL has been shown to have a substantial role in plant response to growth, reproduction, development, and different stress factors. In addition to its regulatory role, MEL also plays a protective role against different abiotic stresses such as metal toxicity, temperature, drought, and salinity. In plants, an important role of MEL is to alleviate the effects of abiotic stresses. In this review, the effects of MEL on plant growth, photosynthetic activity, metabolism, physiology, and biochemistry under abiotic stress conditions as a plant growth regulator will be examined.

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.

This book highlights the multifunctional role of the ubiquitous molecule, melatonin, in crop plants. The major focus of this edition is to provide detailed insights into morphophysiological, biochemical, and molecular responses of melatonin in the growth and development of the plant. The inception of melatonin as an animal hormone and the subsequent discovery of its multifaceted function in the animal system has triggered the research on this pineal gland hormone. During the last decade, the discovery, quantification and functional studies of melatonin as phytohormone has emerged at a rapid pace. Recently, this phyto-protectant has become an integral component of lab and field-based research on the mitigation of adverse effects of climate-driven abiotic stresses and postharvest biology and technology. The book explores various biosynthetic pathways and detection of melatonin covering its role in flowering, fruit development, photosynthesis, respiration, hormonal crosstalk, post-harvest biology and reactive oxygen species and nitrogen cycles. This book is of high interest to postharvest industries, horticulturists, scientists, researchers, and students.

"Melatonin (N-acetyl-5-methoxytryptamine) is a widely studied biomolecule and its function has been investigated in bacteria, mammals, birds, amphibians, reptiles, fish, and plants. Melatonin research in plants since the last five years has attained an exponential growth phase and the number of publications related to phytomelatonin has significantly increased in the present times. All this research is directed towards establishing multifarious roles of melatonin in plants, including the promotion of seed germination and seedling growth, influencing plant development and senescence, alteration of flowering and fruiting time and grain yield, modulating circadian rhythms, improving resistance against biotic stress as well as tolerance to abiotic stress, reducing oxidative stress, and stimulating plant immune response. However, to date, an exhaustive book, solely and exclusively dedicated to melatonin research on various aspects of plant biology, has not been published by any renowned publisher or is available in the market. Keeping all these facts in mind, this book aims to compile the most recent developments in the arena of melatonin-mediated regulation of plant physiology under optimal and sub-optimal conditions. This book will initiate and introduce the readers to the state-of-the-art developments and trends in this field of study and will largely cater to the scientific need of scientists engaged in melatonin research across the globe. The book will be unique of its kind and will highly draw the attention of scientific and research communities engaged in the field of melatonin research. The key features of this book include: Authors will address the topics which would provide advances in the understanding of diverse functions of melatonin in plants, encompassing almost all the aspects that have been investigated so far. Integrate the overall mechanistic function of melatonin, genomics and proteomics tools, and genetic engineering to manipulate endogenous melatonin levels, thus giving a holistic view of plant-level studies under normal or challenging situations. Largely help the readers to design future research programs in exploiting melatonin as a protective agent to develop climate-resilient and pathogen-resistant plants. Benefit the crop protection program and ensure food security. Chapters will be supplemented with ample illustrations and figures. This book will be beneficial to research scholars and Ph.D. students, involved in melatonin research and working on stress physiology, stress proteins, genomics, proteomics, and genetic engineering in different universities and research institutes all over the world. The book can also be used as an advanced reference book for the course work of research and master's level students. It will be of use to people involved in improving plant growth and yield, as well as the performance of plant species in the face of climate change and pathogen infection, using melatonin as the prime protective agent and signaling molecule. Although the book will directly benefit the academic and scientific community, it will also indirectly draw the attention of industries or companies that manufacture or sell chemical products, since the book will highlight in detail the antioxidative potential of melatonin. This will create impetus at the industrial level for the isolation and synthesis of melatonin as a beneficial chemical agent. Applying melatonin as an ameliorating agent against different stresses at the field level will also increase the demand for this chemical among the farmers and will promote large-scale sales and utilization of melatonin for ensuring crop protection and increasing yield"--

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.
