With the development of tea industry, understanding differences in root zone microecology among different varieties is great significance for improving quality and yield. To investigate microbial metabolite foundation underlying disparities physicochemical properties between high-aroma new variety JL4 (Jinlong No.4) its grandparent HD (Huangdan), bacterial diversity, community structure distinctions soils were analyzed using NovaSeq 6000 high-throughput sequencing GC-MS-derived metabolomics technologies. The analysis soil physical chemical showed that, compared with HD, available phosphorus (AP) was significantly decreased (28.91 ± 9.78 mg · kg −1 , P < 0.05), so potassium (AK) at 57.67 4.04 . results from 16S rDNA indicated had a lower Shannon index higher abundance Gram-negative aerobic-related bacteria. These that there decrease diversity JL4. dominant phyla included Proteobacteria Acidobacteriota Chloroflexi others. Biomarkers Firmicutes Rhizobiales Caulobacterales biomarkers comprised Sphingomonadaceae bacterium URHD0088 Halomonadaceae GC-MS derivatization highlighted sugars as having most differential metabolites (8). In JL4, D-manitol 2 scylo-inositol while (-)-epicatechin, catechin, D-pinitol increased. KEGG pathway enrichment revealed substantial metabolic pathways related to flavonoid biosynthesis. changes these may have significant impact on growth plants. Redundancy Analysis (RDA) along correlation analyses impacts by factors such AK, Soil Organic Matter (SOM), NO 3 − -N (nitrate nitrogen), pH levels. A positive observed AK both Kapabacteria individually; furthermore, AP exhibited highly but negative unidentified Archaea Catechin (-)-Epicatechin negatively correlated Actinobacteria phylum showing Verrucomicrobia Kryptonia phyla. This study systematically characteristics first time, providing ideas methods improvement precision cultivation management, which expected promote high-quality industry future.

The utilization of aerospace mutagenesis in plant breeding is a novel, efficient technology. This study investigates the effects on tea tree growth, soil nutrient conversion, and microbial community structure function. results showed that mutagenized trees increased leaf area, 100-bud weight, yield. rhizosphere displayed an increase microorganisms, enhanced carbon nitrogen cycling capacity, significant increases conversion antioxidant enzyme activities. In addition, content available nutrients was also increased. Aerospace abundance soil-characteristic microorganisms (Solirubrobacterales bacterium, Capillimicrobium parvum, Mycobacterium colombiense, rhizamassiliense, Conexibacter woesei), enhancement intensity metabolic pathways, glyoxylate dicarboxylate metabolism, biosynthesis secondary metabolites, metabolism diverse environments, fatty acid amino acids, cofactors microorganisms. Interaction network partial least squares structural equation modeling (PLS-SEM) analysis after mutagenesis, positively affected functions, biomass nitrogen, respiration intensity, activities; furthermore, it improved growth. provides important reference for cultivation management regulation
