  "abstract": "Grasses comprise many of the world's major cereal crops, yet the physiological mechanisms underlying their resilience to environmental stress remain unclear. While C 4 grasses tend to display higher water-use efficiency than C 3 grasses, little is known about the underlying physiological and structural dynamics during mild and severe dehydration. We tested the sequence of decline with dehydration in leaf, root, and whole-plant hydraulic functions, and in leaf gas exchange and photochemistry (F v /F m ) across three C 3 and three C 4 grass crop species, along with their rehydration capacity post-dehydration. We observed distinct strategies between the C 3 and C 4 species in response to water stress. The three C 4 species experienced their peak intrinsic water-use efficiency earlier during dehydration, displayed greater hydraulic supply relative to demand, and had higher turgor loss points. The three C 4 species also showed greater resistance to photochemical damage and embolism under severe dehydration. The three C 4 species had higher leaf capacitance, and experienced greater leaf shrinkage than the three C 3 species. Our findings reveal that variation among photosynthetic types can be associated with contrasts in both drought avoidance and resistance traits, contributing to a broader understanding of how different photosynthetic pathways influence plant performance under stress.",
