Considerable biological decline of continuously cropped alfalfa may be tightly linked to rhizosphere metabolism. However, plant-soil feedbacks and age-related metabolic changes in stands remain unexplored. The aim this study was identify the linkages root metabolites, particularly autotoxins prebiotics, under continuous cropping. We performed liquid chromatography–mass spectrometry for non-targeted metabolomic profiling soils roots 2- 6-year-old stands. Differentially abundant metabolites that responded stand age associated pathways were identified. Compared with bulk soils, enriched more triterpenoid saponins (e.g., medicagenic acid glycosides), which showed inhibitory effects on seed germination seedling growth. These autotoxic accumulated old age, their relative abundances negatively correlated plant growth, yield, quality traits, as well soil total nitrogen alkali-hydrolyzable concentrations. In contrast, prebiotic represented by glycerolipids glycerophosphocholine) fatty acyls colnelenic acid), depleted stand. positively traits available phosphorus Age-induced metabolome mirrored reprogramming patterns metabolome. terpenoid backbone biosynthesis hormone signal transduction, metabolism galactose, glycerophospholipid, ɑ-linolenic affected age. upregulation plants, stimulated saponin exudation. Rhizosphere accumulation accompanied depletion leading degradation exacerbating decline. This research aids development prebiotics prevent manage cropping obstacles alfalfa.

Undisturbed soils are essential ecosystems with high microbial diversity. Microorganisms present in the soil can regulate biogeochemical cycles, making available and transforming different minerals soil, such as nitrogen, phosphorus sulfur. In this study, microbiota of undisturbed was characterized using an integrated approach 16S rRNA ribosomal gene amplicon analysis classical microbiology techniques. Phylum-level analyses revealed a abundance Proteobacteria, Acidobacteria, Verrucomicrobia Actinobacteria, key groups nutrient recycling, organic matter decomposition plant-microorganism interaction. genus analysis, Nitrospira spp., Candidatus Koribacter Burkholderia Bacillus Flavobacterium spp. Pedomicrobium were identified, important functions nitrification, plant growth promotion, degradation, recovery degraded soils. On other hand, by selective differential media, it possible to demonstrate presence microorganisms Enterobacter Hafnia ability solubilize potassium produce siderophores, which likely contributing cycles within studied.

Pogostemon cablin (Patchouli), an essential medicinal plant in the Lamiaceae family, faces significant challenges under continuous cropping (CC) obstacles. This study examined rhizospheric soil bacterial communities of patchouli four different CC years, zero (CK), one (T1), two (T2), and three (T3) years through high-throughput 16S rRNA gene amplicon sequencing. Results showed long-term led to properties enzyme activity shifts. Key parameters such as pH total potassium (TK) decreased, while ammonium nitrogen (NH4+–N), organic carbon (SOC), nitrate (NO3−–N), available (AK), phosphorus (AP), (TN), (TP) increased over years. Enzyme activities, including ß-glucosidase (ß-GC), polyphenol oxidase (PPO), catalase (CAT), N-acetyl-β-D-glucosaminidase (NAG), leucine aminopeptidase (LAP), were notably affected. The altered community structure composition, reducing relative abundance Proteobacteria, Firmicutes, Actinobacteria, Planctomycetota time. These findings highlight impact on rhizosphere bacteria, providing insights for improved management fertilization strategies systems.
