To comprehend the organizational principle of cellular functions at diff erent levels, anintegrative approach with large-scale experiments, the so-called omics data includinggenomics, transcriptomics, proteomics, and metabolomics, is needed. Omics aims atthe collective characterization and quantifi cation of pools of biological molecules thattranslate into the structure, function, and dynamics of an organism or organisms.Currently, omics is an essential tool to understand the molecular systems that underlievarious plant functions. Furthermore, in several plant species, the development of omicsresources has progressed to address the particular biological properties of individualspecies. Integration of knowledge from omics-based research is an emerging issueas researchers seek to identify significance, gain biological insights and promotetranslational research. From these perspectives, we intend to provide the emergingaspects of plant systems research based on omics and bioinformatics analyses togetherwith their associated resources and technological advances. Th e present book covers awide range of omics topics, and discusses the latest trends and application area of plantsciences. In this volume, we have highlighted the working solutions as well as openproblems and future challenges in plant omics studies. We believe that this book willinitiate and introduce readers to state-of-the-art developments and trends in omics-drivenresearch.
