ABSTRACT Nano‐selenium fertilizers can promote plant growth and nitrogen availability. However, little information is available on the effects of nano‐selenium tea leaf quality, soil nutrient availability associated microbe‐driven mechanisms. This study examined quality cycling in 20‐year‐old plantations when leaves were sprayed with ammonium or nitrate. Leaf selenium amino acid contents increased ninefold 9%, respectively, “Zhongcha108” “Longjing43.” Rhizosphere bacterial fungal community compositions more sensitive to applications “Longjing43” than “Zhongcha108.” enriched taxa related microbial growth, while cellular maintenance acquisition application decreased copy number AOA AOB genes, nosZ nirK genes by 59%, 53%, 37% 46% under ammonium, 77%, 43%, 38% 65%, nitrate spraying, expression these spraying. It concluded that a increases this effect ecological functioning largely depends cultivar‐specific composition function.

Phyllosphere microbiome plays important roles in crop adaptation to the changing environments. Perennial woody crops undergo annual cycles with weather parameters and biological factors, which might shape phyllosphere microbial community. In this study, we aimed investigate dynamics of pomelo (Citrus maxima (Burm.) Merr.), an economically horticultural worldwide, compare respective contribution biotic factors community assembly, special focus on amino acids leaves. Hi-Seq analysis revealed that both bacterial fungal communities showed cycle dynamics, summer was much different from those other seasons probably due high temperature precipitation. However, (e.g., leaf traits) (12%-29%) assembly higher than (4%-15%). Redundancy indicated significantly affected while sugars community, highlighting differential patterns as by factors. Finally, structure equation model influenced colonizing leaves a direct way indirect via traits (mainly acids). These results demonstrate primary role key shaping microbiome.

Plant microbiomes provide significant fitness advantages to their plant hosts, especially in the sub-nival belt. Studies date have primarily focused on belowground communities this region. Here, we utilized high-throughput DNA sequencing quantify bacterial rhizosphere soil as well root and leaf endosphere compartments of Silene nigrescens uncover differentiation interconnections these along soil-to-plant continuum. Our findings reveal that exhibit notable variation across different compartment niches: soil, endosphere, endosphere. There was a progressive decline diversity, network complexity, modularity, niche breadth from further Conversely, both host selection effect stability showed an increasing trend. Total nitrogen total potassium emerged crucial factors accounting for observed differences diversity composition, respectively. Additionally, 3.6% amplicon sequence variants (ASVs) were shared Source-tracking analysis revealed community migration among compartments. The genera Pseudomonas, IMCC26256, Mycobacterium, Phyllobacterium, Sphingomonas constituted core microbiome. These taxa are all three niches function key connector species. Notably, Pseudomonas stands out predominant taxon bacteria, with being most factor influencing its relative abundance. deepen our understanding assembly principles ecological dynamics microbiome belt, offering integrated framework study.
