MicroRNAs (miRNAs) are small (20–24 nt), single stranded, regulatory RNA molecules or gene regulators of critical transcriptional or post-transcriptional gene regulation in plants in sequence-specific order that respond to numerous abiotic stresses and animals, non-coding, highly evolutionarily conserved and widely distributed throughout the plant kingdom. MiRNAs are master regulators of plant growth and development, development attenuation under various environmental stresses by stress-responsive miRNAs and plant stress responses and tolerance. Drought, salinity, heat, cold, UV radiation, heavy metal, pathogens, pests and other microbial infections affect survival, growth, development, quality, yield, and production of plants. Stress induced miRNAs down regulate their target miRNAs. This down regulation leads to the accumulation and function of positive regulators, highlighting their roles in stress responses and tolerance. Plant miRNA mediated modifications include overexpression or repression of stress-responsive miRNAs and/or their target complementary or partially complementary gene products, miRNA-resistant target genes, target-mimics and artificial miRNAs. Thus, miRNAs may serve as "genomic gold mines", novel, potent and potential targets in plant genetic manipulations and miRNA-based biotechnology will aid plant improvement and crop-plant tolerance to different environmental stresses. This book reviews our recent understanding of plant microRNAs, biogenesis and functions, computational tools and bioinformatics, regulation of plant growth and development, expression studies, and the role of plant miRNAs in various biotic and abiotic stress-response regulation in plants.

Precise regulation of gene expression in both time and space is vital to plant growth, development and adaptation to biotic and abiotic stress conditions. This is achieved by multiple mechanisms, with perhaps the most important control being exerted at the level of transcription. However, with the recent discovery of microRNAs another ubiquitous mode of gene regulation that occurs at the post-transcriptional level has been identified. MicroRNAs can silence gene expression by targeting complementary or partially complementary mRNAs for degradation or translational inhibition. Recent studies have revealed that microRNAs play fundamental roles in plant growth and development, as well as in adaptation to biotic and abiotic stresses. This book highlights the roles of individual miRNAs that control and regulate diverse aspects of plant processes.

Plants have to manage a series of environmental stresses throughout their entire lifespan. Among these, abiotic stress is the most detrimental; one that is responsible for nearly 50% of crop yield reduction and appears to be a potential threat to global food security in coming decades. Plant growth and development reduces drastically due to adverse effects of abiotic stresses. It has been estimated that crop can exhibit only 30% of their genetic potentiality under abiotic stress condition. So, this is a fundamental need to understand the stress responses to facilitate breeders to develop stress resistant and stress tolerant cultivars along with good management practices to withstand abiotic stresses. Also, a holistic approach to understanding the molecular and biochemical interactions of plants is important to implement the knowledge of resistance mechanisms under abiotic stresses. Agronomic practices like selecting cultivars that is tolerant to wide range of climatic condition, planting date, irrigation scheduling, fertilizer management could be some of the effective short-term adaptive tools to fight against abiotic stresses. In addition, “system biology” and “omics approaches” in recent studies offer a long-term opportunity at the molecular level in dealing with abiotic stresses. The genetic approach, for example, selection and identification of major conditioning genes by linkage mapping and quantitative trait loci (QTL), production of mutant genes and transgenic introduction of novel genes, has imparted some tolerant characteristics in crop varieties from their wild ancestors. Recently research has revealed the interactions between micro-RNAs (miRNAs) and plant stress responses exposed to salinity, freezing stress and dehydration. Accordingly transgenic approaches to generate stress-tolerant plant are one of the most interesting researches to date. This book presents the recent development of agronomic and molecular approaches in conferring plant abiotic stress tolerance in an organized way. The present volume will be of great interest among research students and teaching community, and can also be used as reference material by professional researchers.

This book summarizes the latest findings on the functions of microRNAs in the regulation of plant development and responses to the surrounding environment. MicroRNAs are an important class of molecules that can be found in diverse groups of organisms, including plants and animals, and the investigation of their roles is a highly dynamic and “hot” research topic. The respective chapters address four main aspects, namely: microRNA investigation and annotation, the regulatory roles of microRNAs in various developmental processes, in response to abiotic factors, and in the context of biotic stress response regulation. Systematically reviewing the most important findings in this field, the book offers an essential guide for undergraduate and graduate students, teachers, and plant science researchers. Due to the potential applications of microRNAs in crop breeding and plant protection, it also represents a valuable resource for scientists in academia and the private sector alike.

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.
