Plants, being sessile, are negatively affected by the biotic and abiotic (environmental) stresses, reducing plant growth, productivity, and quality to a larger extent. Plants have evolved different physiological, biochemical, and molecular mechanisms to combat these stress conditions to maintain their growth, development, and productivity. Understanding the mechanisms involved in the plant response to stress conditions is the foremost step in the development of stress-tolerant plants. One of the important adaptations to stress conditions is the precise and fine regulation of gene expression in both time and space. Although gene regulation occurs at different levels through different mechanisms, the most crucial is at the level of transcription. One of the important posttranscriptional gene regulatory mechanisms used by the plants to restore and maintain cellular homeostasis during the stress conditions are microRNAs.MicroRNAs, a group of approximately 22-nucleotide-long, non-coding RNAs, have recently been identified as a new class of regulators governing gene expression at the post-transcriptional level. MiRNAs can silence genes either by guiding the degradation of the target mRNAs or by repressing the mRNA translation. Plant miRNAs have been demonstrated to regulate many genes involved in various developmental processes, for example, auxin signaling, organ polarity/radial patterning, developmental transitions, and secondary metabolism regulation. Moreover, increasing evidence indicates the role of plant miRNA-guided gene regulation in response to biotic and abiotic stresses. High-throughput sequencing approaches have significantly elucidated the identification and functional characterization of numerous miRNAs in plants. Understanding the role and mechanism of action of miRNAs during abiotic and biotic stresses can potentially offer new approaches to improve plant growth and productivity.This unique book covers the different aspects of plant microRNAomics including the discovery, biogenesis, role in different stress conditions, and applications of microRNAs in developing stress-tolerant plants. Chapters cover the updated knowledge in the field of plant microRNA research. The book, miRNAomics and Stress Management in Plants, intends to demonstrate the breadth of research and the significant advances that have been made in understanding the role of miRNAs in the plant development and stress management.This comprehensive volume will be of value to plant physiologists, plant biochemists, geneticists, molecular biologists, agronomists, environmental researchers, and graduate and undergraduate students of plant science.

Plants are an indispensable part of human and animal lives for nutrition and health. But pests, diseases and abiotic stress adversely affect crop yield, which ultimately places significant pressure on society to provide food to an increasing population. Moreover, it also encourages increased chemical/pesticide usage on crops, which we see in the biomagnification of toxic and hazardous compounds polluting water bodies, soil and the environment. This condition will continue to worsen in the future due to the resistance-acquiring ability of pathogens against plant defense and chemical treatments. In addition, environmental disturbances and consumer health issues are being reported more promptly than before due to intensive use of pesticides in food production. Plant diseases affect our daily lives, as the use of insecticides and pesticides has become part of our food chain. As a result, precise disease diagnosis and management is crucial in order to avoid huge losses in plant production and related commodities. Accurate detection, precise diagnosis and proper management can play a significant role in keeping plants free from pathogens. In this book, scientists, researchers and scholars share their research knowledge, offering a valuable resource for understanding plant diseases, pathogen interaction and responses to stress through an omics perspective, contributing to further advancements in the fieldDiseases in plants may be caused by various factors, such as viruses, bacteria, fungi and abiotic stress. Disease causes low crop yield, production of poor-quality fruits and grains, and deficiency of nutrients, which have a direct impact on human and animal health. A genomics-based approach can be applied to disease diagnosis; disease outbreak; evolution of plant and pathogen genome for disease outbreak in relation to climate change; and development of long-term strategies for plant health and defense. This book presents an overview of omics technologies and approaches used to understand: the relation between plants and their environment in terms of diseases responses to abiotic stress the genomics of plant–pathogen interaction herbicide-resistance mechanisms the epigenetics of plant–pathogen interaction gene regulation during abiotic stress response the oxidative stress response

In the last 50 years, classical breeding has played a significant role in achieving higher crop productivity, but major crops have reached a plateau in their yield potential. Therefore, the current focus for sustainable intensification of agriculture is the use of biotechnological approaches to enhance the yield potential by combating the yield losses that occur due to abiotic stresses. The abiotic stresses are governed by multigenes, and therefore, a holistic approach is needed to get success in imparting stress tolerance to enhance the yield potential of our crops.Plants face multiple stress conditions during their life stages and adopt several physiological, biochemical, and molecular strategies to combat that, which are sometimes not sufficient to survive, particularly crop plants. The climate change era has created a need to understand the abiotic stresses in a holistic way. Therefore, a deep understanding of multiple abiotic stress mechanisms is necessary to develop crops tolerant to climate fluctuation.With this background, the outline of this book covers the following features:• Agriculture sustainability and molecular understanding of multiple stress tolerance• Systems biology for life-history strategies, conventional and genomic approaches above and underground• Genetic resources and molecular understanding of seed priming• Molecular signaling compounds, cell signal transduction, and crosstalk between plant growth hormones and regulators• Roles Transcription factors, LEA proteins, reactive oxygen species and alternative oxidase• Genome editing, metabolomics, and ‘omics'technologies

Plants are confronted with various environmental stresses, the most prominent of which is biotic stress, which results in yield losses. Biotic stresses include damage caused by microorganisms like bacteria, viruses, fungi, parasites, insects, weeds, and native plants. It occurs to variable degrees in almost all agricultural ecosystems globally. Fungi, bacteria, or viruses may not be present in a given year, although they usually reduce output in the majority of years. Due to changing environmental conditions, plants struggle to attain their full genetic potential for growth and reproduction. This book focuses on understanding the physiological, biochemical, and molecular changes in stressed plants and the mechanisms underlying biotic stress tolerance in plants.

Abiotic stresses such as high temperature, low-temperature, drought, and salinity limit crop productivity worldwide. Understanding plant responses to these stresses is essential for rational engineering of crop plants. In Arabidopsis, the signal transduction pathways for abiotic stresses, light, several phytohormones and pathogenesis have been elucidated. A significant portion of plant genomes (most studies are Arabidopsis and rice genome) encodes for proteins involves in signaling such as receptor, sensors, kinases, phosphatases, transcription factors and transporters/channels. Despite decades of physiological and molecular effort, knowledge pertaining to how plants sense and transduce low and high temperature, low-water availability (drought), water-submergence and salinity signals is still a major question before plant biologists. One major constraint hampering our understanding of these signal transduction processes in plants has been the lack or slow pace of application of molecular genomic and genetics knowledge in the form of gene function. In the post-genomic era, one of the major challenges is investigation and understanding of multiple genes and gene families regulating a particular physiological and developmental aspect of plant life cycle. One of the important physiological processes is regulation of stress response, which leads to adaptation or adjustment in response to adverse stimuli. With the holistic understanding of the signaling pathways involving not only one gene family but multiple genes or gene families, plant biologists can lay a foundation for designing and generating future crops that can withstand the higher degree of environmental stresses (especially abiotic stresses, which are the major cause of crop loss throughout the world) without losing crop yield and productivity. Therefore, in this proposed book, we intend to incorporate the contribution from leading plant biologists to elucidate several aspects of stress signaling by functional genomic approaches.

Stress may be defined as any negative effect or condition that a living organism may suffer. Abiotic stresses, such as salinity, drought, high and low temperatures, ozone, heavy metals and low concentration of nutrients in degraded soils can cause deleterious effects in almost all phonological plant stages, from germination to full plant development. It has been estimated that 70% of the crop yield loss can be attributed to abiotic stresses, especially drought. It is known that plants respond readily when challenged by abiotic stresses by the modified regulation of many genes. This is a manifold response consisting of transcriptional and translational mechanisms that allow the adaptation of plants to many unfavorable environments. This book discusses the regulation of abiotic stress responses in plants; the structural aspects and functional regulation of late embryogenesis abundant genes and proteins conferring abiotic stress tolerance in plants; and dehydration responsive element binding transcription factors.
