Drought stress remains one of the most detrimental abiotic factors, significantly impacting global crop production and posing a severe threat to food security amid the challenges of climate change. While considerable progress has been made in comprehending plant drought responses, a gap continues to exist between fundamental discoveries and their application in real-world agricultural scenarios. Traditional disciplines such as agronomy, physiology, and breeding often work in silos, which constrains the development of truly resilient crop systems. Addressing this critical shortfall, this Research Topic promotes an integrated, trans-disciplinary approach, aiming to blend knowledge from molecular to field levels. This effort seeks to seamlessly connect the mechanistic understanding of drought tolerance traits with pioneering agronomic management and breeding strategies.

This Research Topic aims to present cutting-edge research that offers practical and scalable solutions for enhancing drought tolerance in major crops. It emphasizes interdisciplinary approaches that bridge the gap between theoretical advances and practical agricultural practice. Key objectives include translating mechanisms to management by demonstrating how physiological insights into traits, such as root architecture and stress memory, can inform precision agronomy. Another focus is accelerating genetic gain by showcasing breeding and biotechnological strategies aimed at creating drought-resilient cultivars. Additionally, the scope includes demonstrating real-world impact through validated case studies, illustrating the successful field application and economic feasibility of proposed solutions.

To gather further insights within this comprehensive approach to drought-resilient agriculture, we welcome articles addressing, but not limited to, the following themes:

• Exploration of novel genetic loci and stress-responsive regulators
• Root and shoot phenotyping for resilience traits
• Innovative precision irrigation solutions and water-saving agronomic practices: showcasing sensor-driven, AI-guided, and variable-rate irrigation systems that optimize water use, enhance drought resilience, and demonstrate field-level effectiveness.
• Physiological mechanisms of water-use efficiency and osmotic adjustment
• Leveraging plant-microbe interactions for drought mitigation
• Application of genomics, speed breeding, and gene editing for the development of resilient cultivars

We invite submissions of Original Research, Reviews, Mini-Reviews, Methods, Perspectives, and Case Studies that demonstrate successful transitions from laboratory or greenhouse conditions to field applications.
