The jasmonate ZIM-domain (JAZ) proteins, known as inhibitors in the jasmonic acid (JA) pathway, have been reported to play a protective role against abiotic stress plants. Nevertheless, specific of JAZ proteins rice seedlings under alkaline remains unexplored. In this study, we mainly focus on OsJAZ10, investigating physiological response mechanism and metabolic regulation challenged by stress. Our results revealed that antioxidant enzyme activity osmotic adjustment ability OsJAZ10 overexpression lines were less affected compared WT (Wild-type) line. Metabolomic analysis demonstrated significant accumulation organic acids, including citrate DL-malate, well amino acids such DL-serine, DL-glutamine, threonine, glycine, L-glutamate, plants Besides, was also involved pantothenate CoA biosynthesis, carbon fixation, C5-branched dibasic metabolism Finally, found negatively regulated biosynthesis signaling pathway repressing JA-responsive genes. Overall, research elucidates conferring enhanced tolerance rice, providing valuable insights for development stress-tolerant varieties. potentially stimulates modulating metabolism-assocoated genes
