“…The appropriate soil ecosystem functions are highly correlated with environmental factors such as soil physiochemical properties and enzymes, the soil microbial community structure, and soil metabolism [ 26 , 43 ]. Furthermore, it is also reported that Si can benefit the growth and health of peanuts by modulating environmental factors [ 26 , 44 ].…”

Silicon (Si) has been shown to promote peanut growth and yield, but whether Si can enhance the resistance against peanut bacterial wilt (PBW) caused by Ralstonia solanacearum, identified as a soil-borne pathogen, is still unclear. A question regarding whether Si enhances the resistance of PBW is still unclear. Here, an in vitro R. solanacearum inoculation experiment was conducted to study the effects of Si application on the disease severity and phenotype of peanuts, as well as the microbial ecology of the rhizosphere. Results revealed that Si treatment significantly reduced the disease rate, with a decrement PBW severity of 37.50% as compared to non-Si treatment. The soil available Si (ASi) significantly increased by 13.62–44.87%, and catalase activity improved by 3.01–3.10%, which displayed obvious discrimination between non-Si and Si treatments. Furthermore, the rhizosphere soil bacterial community structures and metabolite profiles dramatically changed under Si treatment. Three significantly changed bacterial taxa were observed, which showed significant abundance under Si treatment, whereas the genus Ralstonia genus was significantly suppressed by Si. Similarly, nine differential metabolites were identified to involve into unsaturated fatty acids via a biosynthesis pathway. Significant correlations were also displayed between soil physiochemical properties and enzymes, the bacterial community, and the differential metabolites by pairwise comparisons. Overall, this study reports that Si application mediated the evolution of soil physicochemical properties, the bacterial community, and metabolite profiles in the soil rhizosphere, which significantly affects the colonization of the Ralstonia genus and provides a new theoretical basis for Si application in PBW prevention.

“…Soil enzyme activity, microbial community structure, and soil metabolism are all linked to the soil's typical ecological processes. 47 The effects of high-molecular-weight PE-particles on soil enzymes (acid phosphatase and protease) and metabolic pathways (membrane transport, amino acid metabolism, and carbohydrate metabolism) were determined, 48 with RDA analysis indicating that changes in soil enzymes and metabolites in the rhizosphere soil were the key factors affecting Deltaproteobacteria, Acidimicrobiia, and Gemmatimonadetes (Figure 7E). 2,4-D butylate generated a dominance of Actinobacteria, Bacilli, and Saccharimonadia as metabolic regulators in the rhizosphere.…”

Frequent and improper use of herbicides disrupts a plant's metabolism, causing oxidative stress that degrades crop quality. However, few studies have examined the inhibitory effects of herbicides on plant growth and defense mechanisms in terms of their impact on soil quality and crop rhizosphere. Therefore, the current study investigated the detrimental impacts of six typical and multilevel herbicides on the microbial community and signal molecules in the soil as well as on the levels of hormones and secondary metabolites in wheat seedlings. Interestingly, bensulfuron-methyl, terbutylazine (TBA), and 2,4-D butylate significantly induced oxidative damage while reducing the number of phytohormones (salicylic acid and jasmonic acid) and secondary metabolites (tricin, quercetin, and caffeic acid) in the roots and leaves compared with the controls, isoproturon, fenoxaprop-p-ethyl, and pretilachlor. At twice the recommended levels (2×), they also decreased the microbial α diversity and, in particular, the abundance of Gammaproteobacteria, Alphaproteobacteria, Actinobacteria, Bacteroidia, Verrucomicrobia, Bacilli, Acidimicrobiia, Deltaproteobacteria, and Gemmatimonadetes by disrupting the level of enzymes (e.g., urease and sucrase) and metabolites (indole-3-acetic acid, salicylic acid, apigenin, 4-hydroxybenzoic acid, DIMBOA, and melatonin) in the rhizosphere soil. Overall, significant exposure to herbicides may inhibit wheat growth by disturbing the microbial composition in the rhizosphere soil and the distribution of secondary metabolites in wheat seedlings.

“…Colzi et al (2022) reported that the large decline in leaf chlorophyll content that occurred in PVC-exposed plants could be linked to the strong capability of this plastic material to reduce the plant concentration of Fe, an element that is involved in the biosynthesis of that pigment (Marschner, 1995). So far, and to the best of our knowledge, the only other work present in literature that examined whether microplastic treatment can affect the plant ion composition is a study by Fu et al (2022) on PE-treated Zea mais plants. They demonstrated that PE pollution altered the soil element adsorption capacity, thus leading to differences in the bioavailability of the elements.…”

“…The leaf amount of Mg and P was significantly lower in PE-treated plants compared to control samples. The negative influence of PE on the plant photosynthetic performance was explained by such plastic-induced impact on the elemental profile of the leaves (Fu et al, 2022).…”
