“…Bacteroidetes has been proposed as an ecologically important player in soil functioning and are therefore recommended as a biological indicator of agricultural soil health [113,114]. More specifically, metagenomic analysis revealed that the abundance of Bacteroidetes was significantly affected by agricultural practices in arable soils [113].…”

“…Actinobacteria can produce spores in response to harsh environments (Boer et al., 2005 ) and are positively associated with plant residue decomposition, inorganic nitrogen fixation, soil aggregate formation, and plant disease resistance (Zhao et al., 2016 ). An increased abundance of Bacteroidetes indicates high‐quality soil (Kruczyńska et al., 2023 ). Myxococcota are widely distributed in agricultural soils and are important in regulating soil microbial community structure and ecosystem functions (Mohr, 2018 ; Wang et al., 2020 ).…”

Root metabolites and soil microbial community structure in the rhizosphere play critical roles in crop growth. Here, we assessed the efficiency of conventional and tissue culture propagation methods in modulating the soil health and microbiota in the rhizosphere of sugarcane (Saccharum officinarum L.) plants. The seeding canes were obtained using newly planted and two‐year ratooned canes propagated by conventional (CSN and CSR) or tissue culture (TCN and TCR) methods. Changes in soil fertility, root metabolites and soil microbial community structure in the rhizosphere of sugarcane plants obtained using these canes were assessed. The activities of soil β‐glucosidase and aminopeptidase, soil microbial biomass nitrogen, and abundances of soil beneficial microbes, both at phyla and genera levels, were significantly higher in the rhizosphere of sugarcane plants in TCN and TCR treatments than those in that of plants in CSN and CSR treatments. Furthermore, flavonoid and flavonol biosynthesis and alanine, aspartate and glutamate metabolism were significantly upregulated in the roots of TCR and TCN plants compared with those in the roots of CSN and CSR plants. These results suggest that the tissue culture propagation method is a sustainable method for sugarcane cultivation to improve soil fertility and health in sugarcane rhizosphere.

“…In this study, the higher abundance of Proteobacteria in the no P treatment may be ascribed to the increase of P-solubilizing and -mineralizing microorganisms, most of which belong to the phylum Proteobacteria ( Wei et al., 2019 ). With respect to Bacteroidota, the increased relative abundance may relate to the increased exudates of rhizosphere soils, especially at the high P level, as these bacteria are reported to be important carbohydrate degraders by secreting diverse sets of carbohydrate-active enzymes ( Kruczynska et al., 2023 ; Zhang et al., 2023b ). Moreover, other bacterial phyla may also respond to P input, as in other research, the addition of P significantly increased only two phyla, Armatimonadetes and Chlorobi ( Ling et al., 2017 ).…”

IntroductionPhosphorus (P), which plays a vital role in plant growth, is continually added to soil to maximize biomass production, leading to excessive P accumulation and water eutrophication.ResultsIn this study, a pot experiment using a subtropical tobacco-growing soil fertilized with four P levels—no P, low P, medium P, and high P—was conducted and rhizosphere and bulk soils were analyzed.ResultsP addition significantly increased tobacco biomass production (except under low P input) and total soil P and available P content (P<0.05), whereas total nitrogen content decreased in the rhizosphere soils, although this was only significant with medium P application. P fertilization also significantly altered the bacterial communities of rhizosphere soils (P<0.05), but those of bulk soils were unchanged (P>0.05). Moreover, a significant difference was found between rhizosphere soils with low (LR) and high (HR) P inputs (P<0.05). Additionally, compared with rhizosphere soils with no P (CKR), Shannon diversity showed a declining trend, which was significant with LR and HR (P<0.05), whereas an increasing tendency was observed for Chao1 diversity except in LR (P>0.05). Functional prediction revealed that P application significantly decreased the total P and N metabolism of microorganisms in rhizosphere soils (P<0.05).DiscussionCollectively, our results indicate that maintaining sustainable agricultural ecosystems under surplus P conditions requires more attention to be directed toward motivating the potential of soil functional microbes in P cycling, rather than just through continual P input.
