Soybean research plays a central role in the pursuit of global nutrition and food security, given the crop’s significance as a source of high-quality protein and essential nutrients. Yet, soybeans frequently encounter a variety of abiotic stresses—such as drought, salinity, and heat—that hinder yield, disrupt symbiotic nitrogen fixation, and challenge metabolic homeostasis. Recent years have seen notable advancements in the application of omics approaches, including genomics, transcriptomics, proteomics, and metabolomics, which reveal the intricate regulatory networks guiding stress responses and nutrient allocation in soybeans. Despite these innovations, a comprehensive understanding that integrates molecular, physiological, and biochemical data remains incomplete; key mechanisms driving robust stress resilience and the translation of this knowledge into crop improvement represent ongoing challenges for the field.

This Research Topic aims to consolidate cutting-edge research at the intersection of molecular biology, physiology, biochemistry, and agronomy, with a specific focus on enhancing stress tolerance in soybeans. By fostering interdisciplinary dialogue, it seeks to elucidate how specific environmental stressors influence core metabolic processes, antioxidant systems, symbiotic nitrogen fixation, and protein biosynthesis. The ultimate objective is to identify actionable genetic targets, physiological markers, and integrated strategies that can be harnessed to breed or engineer soybean cultivars capable of thriving in variable climates while maintaining high nutritional value. This endeavor addresses fundamental questions about the mechanisms underpinning resilience and the pathways leading to sustainable soybean production systems.

The scope of this Research Topic is confined to studies advancing mechanistic and applied understanding of soybean responses to major abiotic stresses, with an emphasis on their nutritional and environmental implications. Contributions are encouraged that bridge molecular discoveries with practical agronomic solutions. To gather further insights in this area, we welcome articles addressing, but not limited to, the following themes:

• Mechanisms of drought, salinity, heat, and nutrient stress tolerance
• Dynamics of nitrogen metabolism, nodulation efficiency, and rhizosphere interactions
• Antioxidant defense systems and redox regulation during abiotic stress
• Integrated omics analyses linking biochemical, physiological, and molecular responses
• Strategies for the development of climate-resilient and nutritionally enhanced soybean varieties
