To explore how endophytic microbial compositions in amaranth roots are influenced by various fertilization methods and to determine whether these microbes associated with amaranthin formation, we conducted an analysis of the community structure. The plants subjected different treatments—conventional without potassium (NP), conventional phosphorus (NK), nitrogen (PK), balanced (NPK)—were examined. results showed that proportions Streptomyces, Actinospica, Burkholderia-Caballeronia-Paraburkholderia under (NPK) treatment were all greater than those (NP) deficiency treatments. In contrast, Phenylobacterium, Acrocalymma, Neocosmospora, Fusarium, Acidovorax, Gibellulopsis, Cladosporium, Dactylonectria, Gibberella nutrient (NP, NK, PK) treatments higher treatment. Additionally, a significantly positive correlation was found between Streptomyces content. Furthermore, Fusarium exhibited negative correlations above suggested endophytes could easily colonize as beneficial microorganisms conditions. other words, (N, P K fertilizers 188.0, 53.0 50.0 kg·hm−2, respectively) recruit more endogenous for improving their growth quality.

Interactions between endophytes (endophytic bacteria and fungi) plants are crucial in maintaining crop fitness agricultural systems, particularly relation to abundant rare subcommunities involved community construction. However, the influence of long-term fertilization on heterogeneous rhizosphere nitrogen phosphorus environments how these conditions affect key root their assembly mechanisms remain unclear. We studied 26th year a field experiment conducted greenhouse with varying levels (CKP0, CKP1, CNP0, CNP1, ONP0, ONP1) assess composition tomato impact yield. employed 16S rRNA fungal ITS region amplicon sequencing investigate endophytic subcommunities, network correlations, core subcommunity structures, species that enhance The results indicated organic manure fertilizers significantly increased soil content, availability (labile P, moderately labile non-labile P). These also affected (based Bray-Curtis distance) processes (βNTI) microbial subcommunities. both bacterial was primarily governed by dispersal limitation, structures being regulated content available (AN) P (MLP). Rare complemented ecological niches co-occurrence network, supporting functions enhancing stability. Nitrogen-adapting provided stronger predictive correlation for yield than phosphorus-adapting Additionally, three genera such as Arthrobacter, Microbacterium, Sphingobium were identified potentially improving improvement. findings revealed distinct fertilization, our understanding better management practices controlling improve intensive ecosystems.

Maize is one of the major crops cultivated in northern Shandong Province and contributes significantly to China's maize production, nitrogen (N) application soil can have a marked impact on yield microbial productivity. The current environmental challenge, which needs urgently be addressed, effectively utilize fertilizer improve crop production without causing stress sustainable agroecosystems. Soil fungi plant health performance through improved nutrient uptake reducing levels. How N influences fungal diversity at spatial patterns remains unclear. In this study, different treatments yields were investigated fields five rates (from 0 120 kg ha−1). High-throughput sequencing internal transcribed spacer (ITS) region revealed that α- β-diversities increased 80 ha−1 (N80) but decreased control (N0) other treatments. Variations NC model predicted strong distribution (R2 = 0.60) among all highest proportion operational taxonomic units (OTUs) (68.99%) was observed N80. study also found complexity co-occurrence network stabilized N80, decrease N120. showed that, relative control, addition abundance Ascomycota phylum level Chaetomium, Fusarium, Mortierella genus levels, with average abundances 5.82%, 1.67%, 19.58%, respectively. Functional ecology analysis indicated upregulated composition ecological communities by stochastic processes. sub-communities positively correlated nitrogen/carbon cycling Moreover, results (3.14 t ha−1) agronomic effects N80 higher than those This demonstrates optimal achieves increases both yield, contributing sustainability scales.
