This study investigated their role in maize response to abiotic stress by comparing an SL\u2010biosynthesis mutant (\n                    <jats:italic>zmccd8<\/jats:italic>\n                    ) with wild\u2010type (WT) seedlings grown for 4\u2009weeks in vermiculite under nutrient and water limitation. Plant growth, time\u2010course pigment accumulation, targeted gene expression, and root transcriptomic profiles were analyzed. Our results showed that\n                    <jats:italic>zmccd8<\/jats:italic>\n                    plants were largely unable to induce leaf senescence and efficient nutrient remobilization toward younger tissues under nitrogen (N) deficiency, a response previously associated with maize adaptation to low N availability. In parallel, the mutant developed a smaller root system, mainly due to limited adventitious root formation, particularly under N shortage. Root transcriptomic profiling revealed that N deficiency strongly affected WT plants, inducing extensive regulation of pathways involved in nitrogen metabolism and transport, secondary metabolism, ethylene and MAPK signaling, oxidative stress responses, and major transcription factor families. These responses were largely absent in the\n                    <jats:italic>zmccd8<\/jats:italic>\n                    mutant, suggesting reduced transcriptional plasticity and compromised capacity to cope with stress\u2010associated oxidative imbalance. Conversely, despite inducing substantial physiological and molecular responses, water stress elicited only modest SL\u2010dependent regulation, with limited and heterogeneous changes between genotypes. Overall, our findings demonstrate that in maize, SLs act in a stress\u2010specific manner, playing a predominant role in acclimatisation to nitrogen deficiency through coordinated regulation of senescence, nutrient remobilization, root architecture, and gene expression, while contributing more marginally to water\u2010stress acclimatisation. These results provide new insights into SLs' role in shaping maize physiological plasticity under abiotic stress conditions.\n
