| Abstract. | Plants have evolved under Earth's constant gravity (1g), and deviations such as hypergravity offers innovative strategies for enhancing crop traits. This study explores the effects of hypergravity on wheat growth, stress tolerance, and crop yield, emphasizing root development and molecular changes. Hypergravity treatment significantly enhanced seedling growth, particularly root morphology across diverse genotypes and environmental conditions. Root growth was driven by increased cell proliferation rather than enlargement, accompanied by lignin deposition and the upregulation of genes related to the cell cycle and cellwall synthesis, strengthening structural stability. These changes extended beyond the seedling stage, improving root biomass and morphology in both greenhouse and field conditions. Proline levels remained consistently elevated, signaling sustained stress adaptation, while enhanced energy metabolism and protein synthesis supported rapid growth. Chlorophyll content increased during early stages but showed no significant changes at later growth stages. Under drought and salinity stress, hypergravity-pretreated seedlings demonstrated better tolerance, with improved growth, increased antioxidant activity, and upregulation of stress-responsive genes. The hypergravity treatment also modulated phytohormones by increasing stress-related hormones while reducing growth-promoting hormones, facilitating robust adaptation to adverse environmental conditions. Although the influence of hypergravity on grain yield varied across genotypes, its significant impact on seedling vigor, root development, and abiotic stress resilience underscores its potential as a seed priming strategy for climate-resilient wheat cultivation. This research elucidates the molecular and physio-biochemical traits driving hypergravity-induced phenotypic changes, including enhanced cell division, lignin deposition, stress-related gene expression, and phytohormone regulation. By bridging laboratory findings with practical applications, the study establishes a solid foundation for integrating hypergravity into sustainable agriculture to enhance crop adaptability and productivity in challenging environmental conditions. |
