“…Notably, 3‐trans‐caffeoyltormentic acid showed a significant positive correlation with the dominant fungi of Saitozyma and Protoglossum (Figure 7), and this phenolic may be the preferred substrate for both of these fungi. It was reported that 3‐trans‐caffeoyltormentic acid is derived from trans‐cinnamic acid (Moeenfard et al, 2014), has insect resistance (Lv et al, 2022), and is associated with pathogenic fungal communities (Kong et al, 2022). Whether Saitozyma and Protoglossum are potentially harmful to soil and plant health needs to be further verified.…”

Understanding soil metabolic diversity and the chemical signals that shape rhizosphere microbial activity is important for protecting plants and improving forest productivity. At present, little information is known about the metabolites in the rhizosphere soil of pecan (Carya illinoinensis) plantation. Based on technologies of untargeted metabolomics and high-throughput sequencing, we investigated differences in the metabolic profiles of rhizosphere and bulk soils and the relationship between metabolites and microorganisms in pecan plantations. The results showed that the abundance of metabolites in rhizosphere soil was significantly higher than that in bulk soil (p < 0.05), especially reflected in plant secondary metabolites and lipids. Orientaloside and marmesin rutinoside were significantly enriched in rhizosphere soil metabolites of pecan at three pecan ages (VIP >1, p < 0.05). The linoleic acid and α-linolenic acid metabolic pathways were significantly enriched in the differential metabolic set (p < 0.01). In addition, tryptophan metabolism, starch and sucrose metabolism, and galactose metabolism were also important factors affecting the rhizosphere metabolic spectrum. Differential metabolites between bulk and rhizosphere soils were more closely associated with bacteria than with fungal communities, particularly in young pecans. With the increasing age of pecans, new significant enrichment of plant secondary metabolites such as cyanidin, 3-trans-caffeoyltormentic acid, N-(1-Deoxy-1-fructosyl) serine and piperdia emerged in the rhizosphere soil.3-trans-caffeoyltormentic acid was positively related to Saitozyma and Protoglossum.Phenylacetaldehyde was positively correlated with Gaiellaceae, Tausonia, and Tuber.This study provides new insights into the mechanisms of interaction between pecans and microorganisms.

“…However, the activities and relative expression of SOD, POD and CAT in the roots of mycorrhizal apple rootstocks were significantly higher than those of non‐mycorrhizal apple rootstocks (Figure 3). Those phenomena indicate that symbionts can ensure the stability of the oxidation system through high enzyme's activity and expression of resistant enzymes to improve the resistance of symbionts to various stress factors (Lv et al, 2022; Debasis et al, 2021). The increase in enzyme activity could effectively enhance the lignification of plants, thicken the cell wall of roots, and set a stronger physical barrier against the invasion of F. solani…”

Fusarium solani exerts detrimental effects on plant growth, which is one of the reasons for the incidence of apple replant disease. Arbuscular mycorrhizal fungi (AMF) enhance plant resistance to Fusarium wilt; however, the mechanism remains poorly understood. Therefore, the present study investigated the symbiosis between apple and AMF and explored the physiology, especially nitrate metabolism, antioxidant defense, and photosynthetic performance, when infected by F. solani. The experiment was carried out with four treatments, namely −AMF − F. solani, −AMF + F. solani, −AMF + F. solani, and + AMF + F. solani. In this study, the −AMF + F. solani treatment increased the activity of enzymes associated with nitrogen metabolism, such as the nitrate and nitrite reductases, in the apple root system. The +AMF + F. solani treatment showed higher antioxidant enzyme activities than the −AMF + F. solani by F. solani infection. The apple seedlings of the +AMF + F. solani treatment decreased reactive oxygen accumulation and reduced the oxidative damages triggered by F. solani infection. The improvement in antioxidant capacity due to the +AMF + F. solani treatment was closely associated with the upregulation of genes related to the antioxidant system. The F. solani infection greatly damaged the photosynthetic process, while the +AMF + F. solani treatment significantly improved it compared to the −AMF + F. solani treatment. In conclusion, the study demonstrated that the apple‐AMF symbiosis plays an active role in regulating the resistance against F. solani infection by enhancing defense response and nitrogen metabolism.

“…Simultaneously, the inoculation of AM fungus improves crop photosynthetic parameters and enhances plant leaf photosynthetic rate and photosynthetic capacity [ 16 ]. It also alters root fatty acid composition and saturation, enhancing the plant’s antioxidant defense system and adaptability to stressful environments, thereby promoting overall plant growth [ 17 , 18 ].…”

Arbuscular mycorrhizal (AM) fungi can enhance the uptake of soil nutrients and water by citrus, promoting its growth. However, the specific mechanisms underlying the action of AM fungi in promoting the growth of citrus were not fully elucidated. This study aimed to explore the role of AM fungi Funneliformis mosseae in the regulatory mechanisms of P. trifoliata growth. Pot experiments combined with non-targeted metabolomics methods were used to observe the growth process and changes in metabolic products of P. trifoliata under the conditions of F. mosseae inoculation. The results showed that F. mosseae could form an excellent symbiotic relationship with P. trifoliata, thereby enhancing the utilization of soil nutrients and significantly promoting its growth. Compared with the control, the plant height, stem diameter, number of leaves, and aboveground and underground dry weight in the F. mosseae inoculation significantly increased by 2.57, 1.29, 1.57, 4.25, and 2.78 times, respectively. Moreover, the root system results confirmed that F. mosseae could substantially promote the growth of P. trifoliata. Meanwhile, the metabolomics data indicated that 361 differential metabolites and 56 metabolic pathways were identified in the roots of P. trifoliata and were inoculated with F. mosseae. This study revealed that the inoculated F. mosseae could participate in ABC transporters by upregulating their participation, glycerophospholipid metabolism, aminoacyl tRNA biosynthesis, tryptophan metabolism and metabolites from five metabolic pathways of benzoxazinoid biosynthesis [mainly enriched in lipid (39.50%) and amino acid-related metabolic pathways] to promote the growth of P. trifoliata.
