Burgeoning world population, decreased water supply and land resources, coupled with climate change, result in severe stress conditions and a great threat to the global food supply. To meet these challenges, exploring Omics Technologies could lead to improved yields of cereals, tubers and grasses that may ensure food security. Improvement of yields through crop improvement and biotechnological means are the need-of-the-hour, and the current book "OMICS-Based Approaches in Plant Biotechnology", reviews the advanced concepts on breeding strategies, OMICS technologies (genomics, transcriptomics and metabolomics) and bioinformatics that help to glean the potential candidate genes/molecules to address unsolved problems related to plant and agricultural crops. The first six chapters of the book are focused on genomics and cover sequencing, functional genomics with examples on insecticide resistant genes, mutation breeding and miRNA technologies. Recent advances in metabolomics studies are elucidated in the next 3 chapters followed by 5 chapters on bioinformatics and advanced techniques in plant biotechnology and crop breeding. The information contained in the volume will help plant breeders, plant biotechnologists, plant biochemists, agriculture scientists and researchers in using this applied research to focus on better crop breeding and stress adaptation strategies.

Introduction
Climate change challenges could be tackled with the advent of techniques in plant biotechnology, which is a key component to usher sustainable food production and productivity. Plant biotechnology has been started with the culturing of plant cells in various media, which depend on the totipotency of the plant cell. Further, with the advancement of genetic engineering, introducing foreign genes into cell and tissue has become an important tool to develop genetically modified (GM) transgenic crops with enhanced/improved characteristics and traits. In recent studies, the plant biotechnology domain has been tremendously changed/shifted from GM crops and gene manipulation to “OMICS”-based approaches to decipher the underlying mechanisms for abiotic and biotic stress tolerance. Advances in instrumentation and technologies revealed that the genomics, proteomics, metabolomics, methylome (epigenetic regulation), bioinformatics, and phenomics have great potential for identifying and characterizing novel traits in plants to meet environmental challenges. To understand the underlying tolerant mechanisms for climate change conditions, an attempt has been made to conglomerate all interdisciplinary branches under one umbrella to emphasize the essentiality of inter-allied sciences for tackling the problem.
To meet the nation’s food demand, fusion of improved varieties with superior genetics to seed chain at appropriate time intervals is inevitable. The primary objective of developing new varieties and hybrids of various crop species will only be achieved through embracing new strategies/technologies and practical implementation for increased productivity. This book is a reflection of the role played by new OMICS technologies in improving the food and nutritional security. Moreover, OMICS potential to use resources effectively for sustainable production has been illustrated vividly to understand the roles of newer technologies.
Agricultural scientists are striving toward the development of appropriate technologies in the form of improved varieties with higher yielding capacity, a wide range of adaptability and resistance to multiple pests, apt for complex and diverse agro-ecological situations. Continued innovations in the field of plant breeding along with the availability of modern tools and techniques provided dividends, enabling varietal development at a much higher pace. Accordingly, in Chapter 1, legume resources such as velvet bean, winged bean, rice bean and lablab bean, which are rich in protein, have been studied using a genomics approach to facilitate toward molecular breeding and gene discovery programs in the near future. Chapter 2 mainly emphasizes the dissection of insecticidal genes and their application for crop improvement. In addition, this chapter throws light over genetically modified crops in controlling pests such as BT technology, and expression of enzymes like chitinase has been explored; it is concluded that transgenic technology coupled with integrated pest management could alleviate the pest problem and enhance the crop productivity. In Chapter 3, miRNA (noncoding small endogenous regulatory RNAs) technologies for crop improvement have been placed for appraisal of latest developments in the domain. miRNAs mediate gene silencing (fully or nearly complementary targets) either through cleavage of target mRNA or translational repression in plants. In this domain, right from first identification of miRNA genes, let-7 and lin-4 from Caenorhabditis elegans, thousands of miRNAs have been identified in plants, and the current MiRBase entries for plants (viridiplantae) have 10,504 mature sequences, which indicates that these molecules could play a prominent role in crop improvement.
Forward genetics approaches are very appealing than conventional genetics; as a result, few chapters are dedicated to forward genetic approaches and their utility in identifying a gene function, investigating the causal locus/gene, and developing thermotolerant plants (see Chapters 4 and 5). Besides genomics and forward genetics approaches, metabolomics is a new branch, which is emerging and helpful to understand the stress-tolerant mechanisms in the plants. As this field is new, Chapter 6 has been focused on metabolomics methodology using single cell type such as the stomatal guard cells that have been used for analyses of the stress-responsive metabolomes when challenged with stressors. Using bioinformatics and statistical approaches, the dataset of explored guard cell metabolome response to a given treatment (bicarbonate) could decipher the cellular mechanisms pertaining to biological events. In Chapter 7, regular procedures for metabolite profiling and metabolomics analysis in plant systems using proton nuclear magnetic resonance (1H NMR) spectroscopy and gas chromatography–mass spectroscopy (GC-MS) have been elucidated. Further, explanation on general experimental workflow, metabolite data acquisition, metabolite profiling, and statistical analysis for metabolomics using MetaboAnalyst have been dealt with.
OMICS techniques have been dynamic and possess massive potential for crop improvement, which is yet to be reaped particularly in medicinal plants. Application of OMICS in the identification of alkaloids and other secondary metabolites could aid in developing novel insecticides. Chapters 8, 9, and 11 particularly deal with OMICS and poly-OMICS approaches not only on medicinal plants but also on systems biology and biofuel production. Moreover, bioinformatics amalgamating with recent techniques such as CRISPR-Cas9, methylome (epigenetic regulation), and phenomics could be more promising and have been duly accorded in Chapters 10, 12, 13, and 14. It is noteworthy to observe that genome editing (GE), a new breeding technology (NBT), has shown potential to transform not only in fundamental research of plant biology but more importantly also for addressing growing challenges of food security. Hence, due accord has been given to introduce the basic concepts of genome editing with CRISPR-Cas9 in Chapter 12. Regulation of copy number of genes has been maintained by methylation pattern and is considered as epigenetic regulation. Recent reports reveal that nucleic acid methylation in plants like Arabidopsis, maize, and rice has shown that H3K9me2-dependent pathway, ribonucleic acid directed nucleic acid methylation pathway, and mobile siRNAs are the key pathways in the regulation of gene copy number, which is explained in Chapter 13. In addition to these domains, phenomics field is emerging, which has great potential to determine the physiological changes occurring in the plants in response to metabolites and physical factors, and also helps in the development of microfluidic devices. To appraise the advancements taking place in the field, Chapter 14 deals about the know-how, interpretation, and applications in plant biology and crop improvement.
This book aims to keep abreast with the advances taking place in OMICS studies that ultimately aid in confronting climatic challenges. Unprecedentedly, this book is diverse, encompassing several chapters with the latest information, emphasizing new aspects. Indeed, this book would be helpful to plant biotechnologists, plant breeders, agricultural biotechnologists, policymakers, and plant physiologists. Students could refer to this book for competitive exams. It is hoped that this book will be an enriching reference material.
