“…[30][31][32][33] In addition, dinotefuran exhibits toxicity effects on bees, earthworms and other organisms to some extent. [34][35][36] Some nanocarriers have been applied for dinotefuran-controlled release, improving its utilization efficiency, decreasing leaching loss, and promoting ecological safety.

“…Tryptophan metabolism is associated with plant cell wall biosynthesis. 30 We observed a striking induction of cysteine in both Cd-sensitive and -tolerant genotypes, which may significantly contribute to Cd tolerance, implying a potential conserved resistant strategy in rice. The enhancement of lysine in NH224 and the depletion of serine in NH199 indicated that more PCs could be synthesized in the root of NH224, alleviating Cd toxicity.…”

Cadmium (Cd) pollution reduces rice production and quality, putting food security and human health at risk. We conducted comparative physiology and metabolomic analyses in two indica rice ('NH199' and 'NH224') to elucidate the Cdtolerance mechanism. Cd hampered rice growth, induced oxidative stress, and changed the metabolomics profiling of the root. The biochemical and physiological analysis demonstrated that NH224 exhibited a more potent Cd-tolerance ability than NH199. Cd was primarily distributed in root, and NH224 had a lower Cd translocation factor than NH199 by about 24%. The metabolomic analysis revealed 180 and 177 differentially accumulated metabolites between Cd-stressed seedlings and the controls in NH224 and NH199, respectively. In NH224, amino acids biosynthesis, hormone metabolism, lipids-related metabolism, phenylalanine metabolism, and phenylpropanoid biosynthesis pathways were more active and highly associated with antioxidant defense system, biosynthesis of the cell wall and phytochelatins, and maintenance of plasma membrane stability. These findings provide insights into the metabolic profiles of rice following Cd stress and the screening and breeding of Cd-tolerant rice varieties.

“…The release of root exudates is a dynamic process and may be greatly influenced by various environmental stress factors; it affects not only the soil ecosystem structure and resilience but also plant–soil feedback and long-term ecosystem maintenance, soil function, and stability (including nitrification) ( Williams and de Vries, 2020 ; Li Y. et al, 2021 ). Plant metabolites are diverse and have complex metabolic pathways; therefore, differential metabolite detection and metabolic pathway analysis may reflect the state during plant growth.…”

“…The emergence and development of metabolomics provide new ideas for this research. Metabolomics is derived from systems biology and identifies significant differences in key biomarkers and has been widely used in defining the tolerance response of plants under external circumstances, which has an increasingly important role in revealing the basic activities and laws of life ( Li X. et al, 2021 ).…”

Phytoremediation is a promising remediation strategy for degraded soil restoration. Root exudates are the main carrier substances for information communication and energy transfer between plant roots and soil, which play non-negligible roles in the restoration process. This work investigated the adaptation of Leymus chinensis root exudates to different degraded levels of soil and the mechanism of rhizosphere restoration in a 3-year degraded soil field study. We found that the soil quality at each degradation level significantly increased, with the soil organic matter (SOM) content slightly increasing by 1.82%, moderately increasing by 3.27%, and severely increasing by 3.59%, and there were significant increases in the contents of available nutrients such as available phosphorus (AP), ammonia nitrogen (AN), and nitrate nitrogen (NN). The physiological activities indicated that root tissue cells also mobilize oxidative stress to respond to the soil environment pressure. A total of 473 main components were obtained from root exudates by gas chromatography–time-of-flight mass spectrometry (GC–TOFMS), including acids, alcohols, carbohydrates, and other major primary metabolites. OPLS-DA revealed that soil degradation exerted an important influence on the metabolic characteristics of root exudates, and the numbers of both up- and downregulated metabolic characteristic peaks increased with the increase in the degree of degradation. Forty-three metabolites underwent clear changes, including some defense-related metabolites and osmotic adjustment substances that were significantly changed. These changes mainly mobilized a series of lipid metabolism pathways to maintain the fluidity of membrane function and help plants adapt to unfavorable soil environmental conditions. The PPP energy metabolism pathway was mobilized in response to slight degradation, and TCA energy pathways responded to the environmental pressure of severe soil degradation.
