Phosphate-solubilizing bacteria (PSB), nitrogen-fixing bacteria (NFB), and AMF have mutually beneficial relationships with plants, but the effects of their interactions on plant growth by regulating rhizosphere fungal community have not been sufficiently studied. In this study, a greenhouse pot experiment was conducted to investigate the interactions between AMF and bacteria (PSB and NFB) on the growth of <em>Lotus corniculatus</em> L. Specifically, the role of rhizosphere fungal community in the growth of <em>Lotus corniculatus</em> L. was explored using Illumina MiSeq high-throughput sequencing. The results showed that combined inoculation of AMF with PSB and NFB increased plant biomass, plant height, and fungal colonization rate. The richness, complexity, and stability of rhizosphere fungal community also increased after combined inoculation of AMF with PSB and/or NFB, particularly with PSB. In addition, combined inoculation of AMF with PSB and NFB enriched the abundance of beneficial microorganisms, with <em>Chaetomium</em> and <em>Humicola</em> showing the greatest alterations. The structural equation model showed that the interactions of AMF with PSB and NFB promoted plant growth by affecting fungal network structure and soil enzyme activities involved in carbon, nitrogen, and phosphorus cycling. These findings provide evidence for the effects of interactions of AMF with PSB and NFB on rhizosphere fungal community and plant growth.</p></div>","PeriodicalId":49709,"journal":{"name":"Pedosphere","volume":"34 2","pages":"Pages 411-423"},"PeriodicalIF":5.7,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138623504","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}

The potential genes may express differently or dominate the symbiotic relationships between arbuscular mycorrhizal fungi (AMF) and plants, which may be beneficial to rice breeding. To date, research on this important topic has been limited. In this study, we aimed to examine the symbiotic relationships of Asian common wild and cultivated rice species with AMF. By conducting a comparative metagenomic analysis of the rhizospheres of wild and cultivated rice species, we identified differences in <em>Rhizophagus intraradices</em>-related genes associated with wild and cultivated rice, as well as functional genes of AMF. Furthermore, we obtained root-related genes associated with AMF from transcriptome data of rice roots. Our results collectively suggest that <em>R. intraradices</em>-related genes in the rhizosphere of wild rice may be more conducive to its colonization. Additionally, bacteria from the Nitrosomonadaceae and Nitrospiraceae families identified in the rhizosphere of wild rice exhibited positive correlations with <em>R. intraradices</em>-related genes with protein identifiers 1480749 and 1871253, which may indicate that nitrobacteria can enhance the functions of <em>R. intraradices</em> in association with wild rice. Next, in a case study using comparative transcriptome analysis of root samples obtained from <em>R. intraradices</em>-inoculated wild and cultivated rice plants, we found significantly higher expression levels of the strigolactone pathway-related genes <em>DWARF3</em> (<em>D3</em>) and <em>DWARF14</em> (<em>D14</em>) in <em>R. intraradices</em>-inoculated common wild rice than in <em>R. intraradices</em>-inoculated cultivated rice.

We tested four treatments with straw return combined with four nitrogen (N) application rates, <em>i.e</em>., 100%, 80%, 60%, and 0% of the common N application rate (225 kg N ha^-1 year^-1) in this region, and two reference treatments (full or no N application), with three replicates for each treatment. Mycorrhizal colonization was quantified and AMF communities colonizing maize roots were characterized using Illumina sequencing. Forty virtual taxa (VTs) of AMF were identified in root samples, among which VT113 (related to <em>Rhizophagus fasciculatus</em>) and VT156 (related to <em>Dominikia gansuensis</em>) were the predominant taxa. Both root length colonization and AMF VT richness were sensitive to N fertilization, but not to straw return; furthermore, both gradually increased with decreasing N application rate. The VT composition of the AMF community was also affected by N fertilization, but not by straw return, and the community variation could be well explained by soil available N and phosphorus concentrations. Additionally, 60%, 80%, and full N fertilization produced similar maize yields. Thus, our study revealed the response patterns of AMF to straw return and N fertilizer reduction and showed that straw return combined with N fertilizer reduction may be a promising practice to maintain mycorrhizal symbiosis concomitantly with crop productivity.</p></div>","PeriodicalId":49709,"journal":{"name":"Pedosphere","volume":"34 2","pages":"Pages 351-360"},"PeriodicalIF":5.7,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41366357","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}

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.
