To clarify the impact of drought stress during germination on proso millet's physiological responses and metabolic features, this study used targeted-like metabolomics methods. With Longmi No. 7 (drought-tolerant, L1) 15 (drought-sensitive, L2) as materials, we studied enzyme activities, osmotic adjustment substances, differential metabolites millet. Results showed that under stress, L1's activities substance contents were significantly higher than L2's, especially at 48-h treatment. 1085 known identified from 24 samples, normal germination, main (amino acids, flavonoids, phytohormone, lipids, sugars, etc.) enriched in amino acid, lipid, sugar, energy metabolism pathways. L2's lipid metabolism, secondary metabolite biosynthesis, acid At 24-h treatment, pathways L1 mainly concentrated carbohydrate nucleotide while those L2 metabolism. 48 h, carbohydrate, biosynthesis other Under organic etc.; phytohormones, acids. This provides a new direction for development millet sprouts. Meanwhile, it offers ideas theoretical bases functional foods regulation nutritional components

Drought stress seriously threatens human food security, and enhancing crops’ drought tolerance is an urgent problem to be solved in breeding. Quinoa known for its high nutritional value strong tolerance, but molecular mechanism response still unclear. In this study, we used drought-tolerant (D2) drought-sensitive (ZK1) quinoa varieties, PEG-6000 was simulate seedlings. Phenotypic physiological biochemical indicators were measured during the seedling stage, LC-MS a metabolite analysis of explore under stress. With intensification stress, chlorophyll content gradually increased, D2 reached maximum at W4, increase 49.85% compared with W1. The total content, photosynthesis rate, stomatal conductance ZK1 significantly lower than moderate severe Metabolomic results showed that 1295 positive ion mode (pos) metabolites 914 negative (neg) identified. Of these, 12(R)-HETE, phosphatidylcholine, monogalactose diester (MGDG), stachyose up-regulated expression Kyoto Encyclopedia Genes Genomes (KEGG) unsaturated fatty acid biosynthesis glycerophospholipid metabolism pathways enriched. summary, our elucidate responds by accumulating sugars, activating metabolism, protecting photosynthetic system. These findings provide new insights breeding varieties study mechanisms.

This study aimed to elucidate responses of the bacterial structure and diversity rhizosphere in flowering broomcorn millet after rehydration following drought stress. In this study, varieties 'Hequ red millet' (A1) 'Yanshu No.10' (A2), known for their different tolerance levels, were selected as experimental materials. The plants subjected stress at stage, while normal watering (A1CK A2CK) served control. Soil samples collected 10 days (A11, A21, A1CK1, A2CK1) 20 (A12, A22, A1CK2, A2CK2) rehydration. High-throughput sequencing technology was employed investigate variations community structure, diversity, metabolic functions time points findings indicated that operational taxonomic units (OTUs) bacteria notably influenced by duration treatment, with a significant decrease OTUs observed However, Alpha not significantly impacted mainly composed
