Endosymbiotic bacteria play a significant role in the co-evolution of insects and plants. However, whether they induce or inhibit host plant defense responses remains unclear. In this study, non-targeted metabolomic sequencing was performed on cotton leaves fed with Wolbachia-infected uninfected spider mites using parthenogenetic backcrossing antibiotic treatment methods. A total 55 differential metabolites were identified, which involved lipids, phenylpropanoids, polyketides. KEGG pathway enrichment analysis revealed seven significantly enriched metabolic pathways. Among them, flavonoid flavonol biosynthesis, glycerophospholipid metabolism, ether lipid metabolism showed extremely differences. leaves, biosynthesis up-regulated, including quercetin myricetin, suggesting that produces more secondary to enhance its capability. Glycerophosphocholine (GPC) sn-glycerol-3-phosphoethanolamine (PE) down-regulated, Wolbachia may impair integrity function cell membranes. The downregulation lysine upregulation L-malic acid indicated infection shorten lifespan mites. At various developmental stages mites, increased expression detoxification metabolism-related genes, gene families such as cytochrome P450, glutathione S-transferase, carboxylesterase, ABC transporters, thereby enhancing capability This study provides theoretical basis for further elucidating mechanisms by endosymbiotic expands framework insect–plant co-evolution.

Agroforestry systems can improve land use efficiency and increase the output of agricultural forestry products. In this study, a camphor forest-winter rapeseed composite system was used as research object from 2023 to 2024. A randomized block experiment set different slopes, S1, S2, S3 (5°, 10°, 15°), forest densities D1, D2, D3 (row spacing 1.5 m × m, 1.0 m) compare single crop (CK) winter analyze its growth status. This study showed that slope density significantly affected indicators rapeseed. Among intercropping treatments, S1D2 performed best. late period (flowering maturity), treatment increased leaf area index, relative chlorophyll content, root (length, surface area, volume), theoretical yield, actual it aboveground biomass per unit area. Although yield on slopes 2.52%, 2.82%, 1.72% lower than monocropping, respectively, ground exposed idle in after trees were cut down September. Intercropping with utilization coverage. The results m), S2D1 (10°, S3D1 (15°, treatments well terms accumulation they be recommended patterns for slopes.

Responses of soil fertility indicators and fungi community diversity to fertilization strategies in legume-grass mixtures

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Май 8, 2025

Alfalfa-grass binary mixtures outperformed monocultures in nutrient use, soil content, and biomass yield. Nonetheless, the impact of fertilization strategies on fungal community composition ecological functions legume-Grass remains under-researched. This study aimed to explore effects different distribution environmental characteristics. A field experiment Gansu, China, has been conducted five strategies-no (CK), three partial methods (+PK, +NK, +NP), balanced (+NPK)-on population richness, composition, drivers. Rhizosphere soils from treatments were sampled investigated using high-throughput ITS sequencing. Compared CK, +NPK led higher capabilities (P< 0.05), organic matter (SOM), available nitrogen (AN), phosphorus (AP), potassium (AK) increased by an average 29.7 %, 42.3 101.2 24.3 respectively; alkaline phosphatase (APA), catalase (CAT), sucrase (SA) 56.6 31.8 46.7 microbial carbon (SMBC), (SMBN), (SMBP) 64.8 65.1 60.4 respectively. The dominant fungi rhizosphere Mortierellomycota Ascomycota, accounting for 82.2%-92.3%. species richness was highest +PK treatment. From NMDS RDA analysis, it can be discerned that SA, AK, CAT key factors influencing structure inter-root alfalfa; SOM awnless brome. Our findings optimal fertilizer strategy mixtures. Results provided a technical basis scientific application development local mixed grassland ecosystems.

Maize–Soybean Rotation and Intercropping Increase Maize Yield by Influencing the Structure and Function of Rhizosphere Soil Fungal Communities

Microorganisms, Год журнала: 2024, Номер 12(8), С. 1620 - 1620

Опубликована: Авг. 8, 2024

Soil-borne diseases are exacerbated by continuous cropping and negatively impact maize health yields. We conducted a long-term (11-year) field experiment in the black soil region of Northeast China to analyze effects different systems on yield rhizosphere fungal community structure function. The included three systems: (CMC), maize-soybean rotation (MSR), intercropping (MSI). MSI MSR resulted 3.30-16.26% lower ear height coefficient 7.43-12.37% higher compared CMC. richness diversity fungi were 7.75-20.26% than relative abundances
