However, we still have limited understanding of how specific microbes contribute to HFA. Here, we examined how variation in HFA relates to differences in soil bacterial diversity and interconnections among co-existing bacteria taxa. A 480-d reciprocal transplant experiment was designed using <i>Schima superba</i> and <i>Zea mays</i> litter collected from forest and farmland ecosystems, respectively. Our findings showed that litter decomposition is associated with specific soil bacterial taxa that generate HFA effects for litter use. The decomposition of labile <i>Z. mays</i> litter in away site increased the biodiversity of soil bacteria, thereby creating more complex and stable co-occurrence networks. In contrast, the decomposition of recalcitrant <i>S. superba</i> litter in away site reduced the interconnections among co-existing taxa by preventing the establishment of specific taxa such as Proteobacteria and Actinobacteria, resulting in less complex and stable networks. The simplified bacterial networks in away sites led to reduced ecosystem functions, including nutrient cycling and decomposition, and were responsible for the generation of HFA in litter decomposition. Furthermore, the effect of soil bacterial diversity on litter mass loss was indirectly driven by network stability, suggesting that interconnections among co-existing taxa enable a better explanation how specific microbes contribute to drive HFA than the diversity metrics. Our results highlight the importance of co-occurrence networks as a key component of microbial biodiversity linking it with litter decomposition.</p>","PeriodicalId":9210,"journal":{"name":"Biology and Fertility of Soils","volume":"56 1","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The diverse mechanisms by which microbes enhance plant tolerance to Al toxicity, such as Al ion absorption, regulation of metal ion transport, adjustment of rhizosphere pH, filtration of Al ions through mycelial networks, and interaction with root traits, have attracted increasing attention. In this review, we focus on the physiological and biochemical effects of Al toxicity on plants, as well as the mechanisms of plant resistance to Al toxicity. We particularly emphasize the interaction between plants and microorganisms, and how microbes could be used to enhance plant tolerance to Al toxicity. Notably, microbial inoculation strategies often face challenges due to the soil properties and competitive exclusion by indigenous soil microbiomes. Despite these challenges, we propose that combining omics techniques with synthetic microbial consortia designed for Al stress may be a more effective approach to addressing the related issues in this research area.

The ratio of both EPS fractions to microbial biomass was lowest in the biodynamic system and highest in the minerally fertilized conventional system, indicating that rhizodeposits and mucilage were predominantly diverted into microbial biomass, rather than into microbial EPS.

We designed a factorial experiment to test the effect of the addition of an organic amendment and of microbial diversity (using four inoculants with different abundance and diversity of soil microbiota), on the resistance of soil functionality against drought in pot mesocosms. Pots were sown with a forage mixture (<i>Lolium rigidum</i> and <i>Medicago polymorpha</i>), and plant productivity, soil chemical properties, and microbial activity and diversity were measured before and after a simulated drought event. The amendment favored soil moisture, enhancing the stability of the productivity of <i>M. polymorpha</i>. In contrast, the manipulation of inoculation load had a limited effect on the resistance of microbiological activity. Indeed, microbial functioning was highly resistant to reduced water inputs, probably related to the prevalence of Gram positive bacteria. Besides, the effect of microbial diversity on soil multifunctionality was limited.
