“…Intense high temperatures contribute to pollen abortion, leading to incomplete pollination and hindering successful reproduction. The delicate balance between pollen and pistil interactions is disrupted under these conditions, further compromising the reproductive process [2]. During waterlogging reduced light intensity, restricted gas diffusion, nutrient leaching, and hypoxia are pronounced effects.…”

Abiotic stresses, including drought, heat, salinity, waterlogging, and toxic metal stress, can negatively impact plant growth, leading to reduced crop yield and quality. Plants employ two key strategies, avoidance and tolerance, to adapt to such stress, making cellular and metabolic adjustments to withstand adverse conditions. Acclimatization results in significant changes in a plant’s proteome, crucial for its stress response. Proteins encoded by a plant’s genome play a vital role in environmental adaptation, supporting biotechnological advancements in plant breeding, utilizing data from proteomic investigations. Proteomics provides unique insights into post-translational modifications and their impact on crop yield. Subcellular proteomics aids in understanding cellular responses and interactions during growth and responses to biotic and abiotic stresses. Proteomic tools, like mass spectrometry, liquid chromatography, protein microarrays, and antibody-based assays, are integral to proteomic studies, contributing to our understanding of protein functions and interactions. Developing stress-tolerant crops is crucial for enhancing crop productivity and growth.

Global agricultural production must double by 2050 to meet the demands of an increasing world human population but this challenge is further exacerbated by climate change. Environmental stress, heat, and drought are key drivers in food security and strongly impacts on crop productivity. Moreover, global warming is threatening the survival of many species including those which we rely on for food production, forcing migration of cultivation areas with further impoverishing of the environment and of the genetic variability of crop species with fall out effects on food security. This review considers the relationship of climatic changes and their bearing on sustainability of natural and agricultural ecosystems, as well as the role of omics-technologies, genomics, proteomics, metabolomics, phenomics and ionomics. The use of resource saving technologies such as precision agriculture and new fertilization technologies are discussed with a focus on their use in breeding plants with higher tolerance and adaptability and as mitigation tools for global warming and climate changes. Nevertheless, plants are exposed to multiple stresses. This study lays the basis for the proposition of a novel research paradigm which is referred to a holistic approach and that went beyond the exclusive concept of crop yield, but that included sustainability, socio-economic impacts of production, commercialization, and agroecosystem management.
