  abstract = {{P}earl millet ({P}ennisetum glaucum) thrives in arid and nutrient-poor environments, establishing its role as a crucial cereal crop for food security in sub-{S}aharan {A}frica. {D}espite its remarkable adaptability, its yields remain below genetic potential, primarily due to limited water and nutrient availability. {I}n this study, we conducted ionomic profiling and genome-wide association studies ({GWAS}) in field conditions across two growing seasons to unravel the genetic basis of nutrient acquisition in pearl millet. {S}oil ion content analyses revealed significant differences in nutrient distribution between field sites, while certain ions, such as phosphorus ({P}) and zinc ({Z}n), consistently displayed stratified accumulation patterns across years, suggesting stable depth-dependent trends. {E}valuation of a genetically diverse panel of inbred lines revealed substantial variation in leaf ion concentrations, with high heritability estimates. {C}orrelations between leaf ion content and root anatomical or agromorphological traits highlighted the intricate interplay between genetic and environmental factors shaping leaf ion accumulation. {T}hese analyses also uncovered potential trade-offs in nutrient acquisition strategies. {GWAS} identified genomic regions associated with leaf ion concentrations, and the integration of genetic and gene expression data facilitated the identification of candidate genes implicated in ion transport and homeostasis. {O}ur findings provide valuable insights into the genetic regulation of nutrient acquisition in pearl millet, offering potential targets for breeding nutrient-efficient and climate-resilient varieties. {T}his study underscores the importance of integrating genetic, physiological, and root architectural traits to enhance agricultural productivity and sustainability in resource-constrained environments.},
