Photosynthesis continues to set the ultimate limit on crop productivity, and the ability of plants to maintain efficient light use, electron transport, and carbon assimilation under variable environments remains central to global food security. As climate change intensifies environmental fluctuations in temperature, light, and water availability, crops are increasingly challenged to sustain growth and yield under conditions that strain their photosynthetic capacity. This Research Topic was developed to highlight current advances in understanding how photosynthetic processes adjust and contribute to crop resilience across a wide range of climatic conditions. This collection brings together four studies that approach this challenge from complementary perspectives. Together, they show that photosynthetic performance cannot be defined by a single trait but emerges from a coordinated system that integrates physiology, agronomy, and genetics. They also demonstrate how adjustments in crop management and experimental design can reveal new opportunities to enhance photosynthetic resilience and productivity. Taken together, the studies in this Research Topic broaden our understanding of how photosynthesis responds to diverse environmental constraints and how crop management strategies can support more effective use of light and carbon resources. The collection shows that progress emerges from approaches that connect molecular and physiological insights with field-level practices and genetic diversity. Looking ahead, closer integration of field physiology with controlled environment analysis and modern phenotyping technologies will help build stronger links between mechanistic understanding and real-world crop performance. Greater attention to stomatal dynamics, canopy light distribution, chloroplast resilience, and the timing of senescence may also reveal new opportunities to strengthen photosynthetic capacity under stress. These perspectives demonstrate how photosynthesis research is expanding beyond the leaf to consider the broader agronomic and genetic context that ultimately determines yield.
