Waterlogging stress is one of prominent abiotic stresses that has a significant impact on the yield and quality barley. Seed germination crucial for seedling establishment highly sensitive to waterlogging stress. However, there limited understanding regulatory mechanisms gene expression metabolic processes in barley during stage under This study aimed investigate metabolome transcriptome responses germinating seeds The findings revealed sharply decreased growth. tolerant genotype (LLZDM) exhibited higher levels antioxidase activities lower malondialdehyde (MDA) content comparison (NN). In addition, induced 86 85 differentially expressed metabolites (DEMs) LLZDM NN, respectively. Concurrently, analysis identified 1776 839 genes (DEGs) Notably, associated with redox reactions, hormone regulation, other biological were altered response Furthermore, integrated transcriptomic metabolomic analyses DEGs DEMs implicated mitigating primarily pertained regulation pyruvate metabolism flavonoid biosynthesis. Moreover, might promote biosynthesis by regulating 15 flavonoid-related 10 metabolites. present research provides deeper insights into overall waterlogging-tolerant process.
