Agriculture is globally challenged by adverse environmental factors, including drought, heat, waterlogging, cold, soil salinity and sodicity, nutrient deficiency, heavy metal contamination, and other edaphic stresses. These stresses impair plant functioning at multiple levels limiting plant development and crop productivity. In the current climate change scenario, the increase in frequency and intensity of these stresses is posing a serious threat to overall food and nutrition security.
Plants respond to these stresses through several tolerance mechanisms operating at molecular, biochemical, physiological, or morpho-anatomical levels depending on their developmental stage and type of species. The cope-up strategy also differs depending on abiotic stress type, duration, and intensity. The extent, to which these changes occur to counteract the impact of abiotic stresses as well as the pathways involved in plant acclimation, is not fully understood. An advance in understanding agricultural crops' adaptation and tolerance mechanisms underlying trans-generational effects, epigenetic changes, and stress memory will significantly help in comprehending the implications as well as devising mitigation strategies for sustainable agriculture and, thus, food security. Additionally, it is crucial to understand the interactions and impacts of combined stresses to efficiently advance the development of combined stress-tolerant crops as well as devising mitigation strategies for various climatic stressors.
This research collection aims to collect contributions focused on an advanced understanding of plant responses to abiotic stresses. Besides efforts being made to manage the emerging and future abiotic stresses through innovative G × E × M (genotype by environment by management) practices for improving the tolerance as well as adaptation and mitigation strategies for enhanced sustainability of crop production systems are welcome in this collection. Also welcome are the articles on improvised mitigation strategies of abiotic stresses through soil, crop, and microbe-mediated management strategies.

This Research Topic welcomes original research articles, methods, reviews, mini-reviews, and opinion papers that address the following topics in field crops, but are not limited to:

• Mechanisms associated with abiotic plants stress tolerance
• Case studies of crop stress physiology
• Signaling in response to abiotic stresses
• Transcriptional and translational regulation of stress response in field crops
• Breeding efforts to develop climate-resilient crop varieties
• Crop genomics and phonemics to identify gaps for tailoring climate smart genotypes
• Mechanism(s) of microbes-mediated alleviation of abiotic stresses
• Soil health management influence on abiotic stresses
• Innovative strategies for the management of abiotic stress regions for enhancing crop
productivity through crop adaptation and mitigation
