"Crop production needs to increase to secure future food supplies, while reducing its impact on ecosystems. Detailed characterization of plant genomes and genetic diversity is crucial for meeting these challenges. Currently, omics is an essential tool to understand the molecular systems that underlie various plant functions. Additionally, in several plant species, the development of omics resources has progressed to address the particular biological properties of individual species. Current Recent developments in genomics, transcriptomics, proteomics, and metabolomics techniques have revolutionized the understanding of genetic response of plants to various biotic and abiotic stresses. Strategic application of this ground-breaking technology will ultimately lead towards achieving sustainability in agriculture. This volume ‘Plant OMICS and Crop Breeding’ covers state-of-the-art technologies widely used to deal various issues pertaining to agriculture including the working solutions as well as open problems and future challenges in plant omics studies. Advances in genome sequencing and assembly are being used to access the large and complex genomes of crops and their wild relatives. These have helped to identify a wide spectrum of genetic variation and permitted the association of genetic diversity with diverse agronomic phenotypes. In combination with improved and automated phenotyping assays and functional genomic studies, genomics is providing new foundations for crop-breeding systems. We believe that this book will initiate and introduce readers to up-to-date developments and trends in omics-driven research."
