"Omics is a collective, wide-range discipline chiefly referring to analysis of the interactions of biological information obtained from the profiling of the genome, transcriptome, proteome, metabolome, and several other relevant -omes. Essentially, the omics science is enabled by a host of diverse, high-throughput technologies and platforms. The full range of omics technologies can now be applied to understand the same fundamental biological processes. Mapping and defining the relationships among genes, proteins, and metabolites require relative comparison of the networks that eventually help in understanding the regulatory mechanisms. These new strategies have begun to piece together the physiological and phenotypic observations with information on transcription and transcript regulation, the behavior of proteins, protein complexes and pathways, and the metabolites and metabolite fluxes, finally shedding light on evolutionary adaptive diversifications of organisms. OMICS Applications in Crop Science is a compilation of several -omics studies, such as genomics, proteomics or metabolomics, to illustrate the applications of these studies in crop productivity, discussing the strengths and weaknesses of -omics technologies and the limitations of current techniques in the perspective of plant biology. The contributed chapters are written by subject matter experts and wide-known researchers with years of research experience in this field. Integration of knowledge from omics-based research is an emerging issue as researchers seek to identify importance, increase biological insights and promote translational research. From these viewpoints, it aims to provide the evolving aspects of plant systems research based on omics and bioinformatics analyses plus their associated resources and technological advances. The present book covers a wide range of omics topics, and discusses the latest trends and application area of crop science."
