However, the combined effects of these two fungi on the growth and cadmium (Cd) tolerance of host plants remain largely unexplored. To address this knowledge gap, a pot experiment was conducted to examine the effects of the interaction between an ECMF strain (<em>Suillus granulatus</em>) and a DSE strain (<em>Pseudopyrenochaeta</em> sp.) on <em>Pinus tabulaeformis</em> under Cd stress, by assessing plant growth and physiological parameters, nutrient uptake, and soil properties. Notably, the colonization rates of both fungal strains were found to increase in response to Cd stress, with the extent of this increase being influenced by the specific fungal species and the Cd level in the soil. Compared to the non-inoculation treatment, single inoculation with fungal strain resulted in enhanced biomass, root development, and nutrient contents in <em>P. tabulaeformis</em> seedlings under Cd stress. Furthermore, a synergistic effect was observed when these seedlings were co-inoculated with <em>S. granulatus</em> and <em>Pseudopyrenochaeta</em> sp., as indicated by significantly greater measurements in various indicators compared to both the single and non-inoculation treatments. Fungal inoculation effectively regulated the antioxidant defense responses and photosynthesis of <em>P. tabulaeformis</em> seedlings subjected to Cd stress, particularly in the co-inoculation treatment. In addition, fungal inoculation facilitated the Cd accumulation in <em>P. tabulaeformis</em>, suggesting a promising potential for the implementation of bioremediation strategies in the areas contaminated with heavy metals. The findings from this study indicate that the utilization of root symbiotic fungi obtained from stress environments could potentially enhance the growth performance and tolerance of <em>P. tabulaeformis</em> towards heavy metals, and co-inoculation of both fungal groups may result in even more pronounced synergistic effects on the overall fitness of the plant.</p></div>","PeriodicalId":49709,"journal":{"name":"Pedosphere","volume":"34 2","pages":"Pages 473-483"},"PeriodicalIF":5.7,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"55352835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since polyamines (PAs) and proline are also associated with stress tolerance, it is hypothesized that the enhancement of stress resistance by symbiotic fungi is associated with changes in PAs and/or proline. The aim of this study was to analyze the effect of inoculation with <em>Funneliformis mosseae</em> and <em>Serendipita indica</em> on plant growth, PAs, and proline and the metabolisms in peach (<em>Prunus persica</em>) under flooding. Two-week flooding did not affect root colonization frequence of <em>F. mosseae</em>, while it promoted root colonization frequence of <em>S. indica</em>. Under flooding, plants inoculated with <em>F. mosseae</em> and <em>S. indica</em> maintained relatively higher growth rates than uninoculated plants. <em>Funneliformis mosseae</em> promoted root ornithine (Orn) contentration and arginine (Arg) and Orn decarboxylase activities under flooding, which promoted putrescine (Put), cadaverine (Cad), and spermidine (Spd) contentrations. Conversely, <em>S. indica</em> decreased contentrations of Arg, Orn, and agmatine and Arg decarboxylase activities, thus decreasing PA contentrations under flooding. Polyamines were negatively correlated with the expression of PA uptake transporter genes, <em>PpPUT1</em> and <em>PpPUT2</em>, in peach. Polyamine transporter genes of <em>F. mosseae</em> (<em>FmTPO</em>) and <em>S. indica</em> (<em>SiTPO</em>) were regulated by flooding, of which <em>FmTPO1</em> was positively correlated with Put, Cad, and Spd, along with positive correlations of Spd with <em>SiTPO1</em>, <em>SiTPO2</em>, and <em>SiTPO4</em>.

Therefore, understanding the role of carbon:nitrogen:P stoichiometries of soil and microorganisms in soil P transformation is of great significance for P management in agriculture. This paper provides a comprehensive review of the recent research on stoichiometry effect on soil P transformation in agricultural ecosystems. Soil microorganisms play an important role in the transformation of soil non-labile inorganic P to microbial biomass P by regulating microbial biomass stoichiometry. They also mobilize soil unavailable organic P into available P by changing ecoenzyme stoichiometry. Organic materials, such as manure and straw, play an important role in promoting the transformation of insoluble P into available P as well. Additionally, periphytic biofilms can reduce P loss from rice field ecosystems. Agricultural stoichiometries are different from those of natural ecosystems and thereby should receive more attention due to the influences of anthropogenic factors. Therefore, it is necessary to conduct further stoichiometry research on the soil biochemical mechanisms underlying P transformation in agricultural ecosystems.
