Global food security is increasingly challenging in light of population increase, the impact of climate change on crop production, and limited land available for agricultural expansion. Plant breeding and other agricultural technologies have contributed considerably for food and nutritional security over the last few decades. Genetic engineering approaches are powerful tools that we have at our disposal to overcome substantial obstacles in the way of efficiency and productivity of current agricultural practices. Genome engineering via CRISPR/Cas9, Cpf1, base editing and prime editing, and OMICs through genomics, transcriptomics, proteomics, phenomics, an metabolomics have  helped to discover underlying mechanisms controlling traits of economic importance.

     Principle and Practices of OMICs and Genome Editing for Crop Improvement provides recent research from eminent scholars from around the world, from various geographical regions, with established expertise on genome editing and OMICs technologies. This book offers a wide range of information on OMICs techniques and their applications to develop biotic, abiotic and climate resilient crops, metabolomics and next generation sequencing for sustainable crop production, integration bioinformatics, and multi-omics for precision plant breeding. Other topics include application of genome editing technologies for food and nutritional security, speed breeding, hybrid seed production, resource use efficiency, epigenetic modifications, transgene free breeding, database and bioinformatics for genome editing, and regulations adopted by various countries around globe for genome edited crops. Both OMICs and genome editing are vigorously utilized by researchers for crop improvement programs; however, there is limited literature available in a single source. This book provides a valuable resource not only for students at undergraduate and postgraduate level but also for researchers, stakeholders, policy makers, and practitioners interested in the potential of genome editing and OMICs for crop improvement programs.

Access to food with enough calories and nutrients is a fundamental right of every human. The global population has exceeded 7.8 billion and is expected to pass 10 billion by 2055. Such rapid population increase presents a great challenge for food supply. More grain production is needed to provide basic calories for humans. Thus, it is crucial to produce 60-110% more food to fill the gap between food production and the demand of future generations.

Meanwhile food nutritional values are of increasing interest to accommodate industrialized modern lives. The instability of food production caused by global climate change presents another great challenge. The global warming rate has become more rapid in recent decades, with more frequent extreme climate change including higher temperatures, drought, and floods. Our world faces various unprecedented scenarios such as rising temperatures, which causes melting glaciers and the resulting various biotic and abiotic stresses, ultimately leading to food scarcity. In these circumstances it is of utmost importance to examine the genetic basis and extensive utilization of germplasm to develop “climate resilient cultivars” through the application of plant breeding and biotechnological tools. Future crops must adapt to these new and unpredictable environments. Crop varieties resistant to biotic and abiotic stresses are also needed as plant disease, insects, drought, high- and low-temperature stresses are expected to be impacted by climate change. Thus, we need a food production system that can simultaneously satisfy societal demands and long-term development.

Since the Green Revolution in the 1960s, farming has been heavily dependent on high input of nitrogen and pesticides. This leads to environmental pollution which is not sustainable in the long run. Therefore, a new breeding scheme is urgently needed to enable sustainable agriculture; including new strategies to develop varieties and crops that have high yield potential, high yield stability, and superior grain quality and nutrition while also using less consumption of water, fertilizer, and chemicals in light of environmental protection.

While we face these challenges, we also have great opportunities, especially with flourishing developments in omics technologies. High-quality reference genomes are becoming available for a larger number of species, with some species having more than one reference genome. The genome-wide re-sequencing of diverse varieties enables the identification of core- and pan-genomes. An integration of omics data will enable a rapid and high-throughput identification of many genes simultaneously for a relevant trait. This will change our current research paradigm fundamentally from single gene analysis to pathway or network analysis. This will also expand our understanding of crop domestication and improvement. In addition, with the knowledge gained from omics data, in combination with new technologies liketargeted gene editing, we can breed new varieties and crops for sustainable agriculture.
