The antioxidant enzyme activity, adjustment substance content, capacity, endogenous hormone content two soybean studied under different degrees treatment durations. caused significant changes in soybean. activities, osmoregulation total capacity (T-AOC) HN65 HN44 showed an increasing trend mild moderate drought, however, they first increased then decreased severe conditions. Following extension time, malondialdehyde (MDA) trend. As increased, gibberellin (GA) a decreasing trend, while abscisic acid (ABA), salicylic (SA), zeatin nucleoside (ZA) auxin (IAA) opposite change trends. In short, had impact physiology these varieties; overall, resistance lower than that HN44. This study provides research theoretical basis for addressing mechanism breeding resistant varieties.

Abstract Amino acids play important roles in stress resistance, plant growth, development, and quality, with roots serving as the primary organs for drought response. We conducted biochemical multi‐omics analyses to investigate metabolic processes of root amino drought‐resistant (HN44) drought‐sensitive (HN65) soybean ( Glycine max ) varieties. Our analysis revealed an increase total acid content both varieties, phenylalanine, proline, methionine accumulating both. Additionally, several exhibited significant decreases HN65 but slight increases HN44. Multi‐omics association identified 13 acid‐related pathways. thoroughly examined changes genes metabolites involved various metabolism/synthesis determined core through correlation networks. The tyrosine, tryptophan pathways glutamic sulfur‐containing were particularly resistance. Some candidate genes, such ProDH P4HA family metabolites, O ‐acetyl‐L‐serine, directly affected up‐ downstream metabolism induce This study provided a basis resistance breeding.

Soybean is the world's most important cultivated crop, and drought can affect their growth and, eventually, yields. Foliar application of mepiquat chloride (MC) potentially alleviate damage caused by stress in plants; however, mechanism MC regulation soybean response has not been studied. This study investigated two varieties soybean, sensitive Heinong 65 (HN65) drought-tolerant Heinong44 (HN44), under three treatment scenarios, normal, stress, + conditions. promoted dry matter accumulation reduced plant height, decreased antioxidant enzyme activity, significantly malondialdehyde content. The light capture processes, photosystems I II, were inhibited; upregulation several amino acids flavonoids was observed. Multi-omics joint analysis indicated 2-oxocarboxylic acid metabolism isoflavone biosynthetic pathways to be core which regulated response.

Drought stress threatens agriculture and food security, significantly impacting soybean yield physiology. Despite the documented role of nanosilica (n-SiO2) in enhancing crop resilience, its full growth-cycle effects on soybeans under drought remain elusive. This study aimed to evaluate efficacy n-SiO2 at a concentration 100 mg kg−1 soil medium for tolerance through life-cycle assessment greenhouse setup. To elucidate mechanisms action, key physiological, biochemical, parameters were systematically measured. The results demonstrated that increased silicon content shoots roots, restored osmotic balance by reducing Na+/K+ ratio 40%, alleviated proline accumulation 35% compared control, thereby mitigating stress. Enzyme activities related nitrogen metabolism, including nitrate reductase (NR) glutamine synthetase (GS), improved 25–30% treatment control. Additionally, antioxidant activity, superoxide dismutase (SOD) levels, 15%, while oxidative markers such as hydrogen peroxide (H2O2) malondialdehyde (MDA) decreased 20–25% Furthermore, components enhanced, with pod number grain weight increasing 15% 20%, respectively, untreated plants conditions.
