Plant systems, both natural and managed, face a wide range of environmental challenges, which are expected to become more intense because of global climate change. Plants have adapted to an incredible range of environments and the fields of ecological and environmental plant physiology have provided mechanistic understanding of the survival, distribution, productivity, and abundance of plant species across the diverse climates of our planet. Ecophysiological techniques have greatly advanced understanding of photosynthesis, respiration, plant water relations and plant responses to abiotic and biotic stresses, from instantaneous to evolutionary timescales. Ecophysiological studies also provide the basis for scaling plant physiological processes from the tissue to the canopy, ecosystem, region and globe. Advancing ecophysiological understanding and approaches to enhance plant responses to new environmental conditions is critical to developing meaningful high-throughput phenotyping tools and maintaining humankind’s supply of goods and services as global climate change intensifies. Therefore, new and improved methods and tools for the production of stress-tolerant plant production with increasing yield and agronomical traits are needed. In recent years, ever-increasing plant multi-omics and bioinformatic tools are used to unravel deeper molecular biological insights imparting plant tolerance to diverse stress mechanisms. The development of last-generation high-throughput screening technologies, known as omics, promises to speed up trait improvement in plants. Hence, this Special Issue aims to integrate recent innovative high-throughput sequencing and computational omics approaches such as genomics, epigenomics, transcriptomics, proteomics, hormonomics, metabolomics, ionomics and phenomics and other related topics which include breeding, biotechnology, biochemistry, systems biology and agricultural practices to make novel progress in delineating the molecular and cellular systems level aspects of stress tolerant plant production. Specifically, we welcome studies that explore the uses of the omics paradigm and their integration through trans-disciplinary bioinformatics, as tools to improve qualitative and quantitative traits in crop species. This issue also illustrates the central role for plant ecophysiology in applying basic research to address current and future challenges to humankind, in particular in conservation of natural ecosystems and adaptation of agriculture to biotic/abiotic stress and global climate change.
