“…Previously, the AM fungal diversity was only studied in single varieties of barley utilizing the taxonomicbased assessment of spores in soil and the molecular characterization in roots (Aguilera et al, 2017;Kaidzu et al 2020). Therefore, our study highlights for the rst time a host plant preference in AMF across barley genotypes.…”

In barley cultivation, high use of mineral fertilisers in combination with low crop nutrient use efficiency results in severe environmental and economic issues. In this context, inoculants with indigenous arbuscular mycorrhizal fungi (AMF) could represent an efficient solution where intensive agriculture negatively impacted soil AM fungal abundance and diversity. However, since crop breeding and environment can strongly affect plant mycorrhizal response, in this work, we tested the agro-ecological effect of field inoculation with a indifìgenous AM fungal consortium on three varieties of barley for two years. In 2020, when soil was clay loam with very low P availability and no drought stress, Atomo and Concerto varieties positively responded to inoculation in terms of AM fungal traits, whereas in 2021, with silty clay loam soil, low P availability and drough stress, only Concerto was responsive. In 2020, inoculation promoted grain yield by 64% and 37% in Atomo and Concerto, and in 2021 by 78% and 134% in Concerto and Atlante. Multivariate analysis highlighted a strong effect of environment on barley productivity and a third-order significant interaction AMF, genotype and environment (65% and 7% of explained variance). Inoculation slightly modified AM fungal composition, it strongly modified, together with plant growth stage, the AM fungal community structures. A significant relationship between root AM fungal abundance and barley productivity was highlighted, with arbuscules as best predictor. Accordingly, changes in AM fungal root community structure and not in composition drove barley response and the main players were Glomus sp. VTX00342 and Septoglomus sp. VTX00064, putative members of the local AM inoculum. The general positive barley productivity outcome supports the use of indigenous AMF for building efficient and ecologically safe inoculants and their inclusion in sustainable agriculture. Nevertheless, the selection of genotypes with stable AM fungal response in specific climatic conditions is crucial in biofertilization programmes.

“…The proportion of species in Glomeraceae exceeded 40% in soil with pH > 6.5 (Stürmer et al, 2018). The dominance of Glomeraceae has been observed in soils as well as in roots subjected to different environmental conditions (Akaji et al, 2022; Kaidzu et al, 2020; Faggioli et al, 2019; Borriello et al, 2012; Öpik et al, 2010).…”

Marginal soils affected by salinity, sodicity and alkalinity decrease crop productivity. In this context, a viable alternative strategy lies in the remediation of degraded lands using beneficial microorganisms. This study aims to characterize native arbuscular mycorrhizal fungal (AMF) communities by sequencing PCR amplicons that cover most of the small subunit rRNA (SSU) gene, the complete internal transcribed spacer (ITS) region, and a portion of the large subunit (LSU) rRNA, employing Oxford Nanopore Technologies (ONT). Three field sites, with varying crop conditions, were selected: a patch with no crop growth (Site 1), a patch with corn stubble (Site 2), and a patch with wheat plants exhibiting 15 days of growth (Site 3). Soil analyses revealed distinct characteristics - alkaline saline sodic soil (ASS) for Site 1, moderately alkaline soil (A) for Site 2, and neutral soil (N) for Site 3. ONT sequencing yielded a total of 4,040,470 raw reads from which 19.13% survived after quality and length filter. Reads were grouped in 556 clusters, of which 222 remained after bioinformatic analysis. Despite moderate error rates in 9.4.1, flowcells chemistry, using a clustering and polishing approach facilitated the ecological analysis and allowed a better taxonomic resolution. Bioinformatic analysis showed no significant differences in AMF diversity among soils. However, results suggest the dominance of Glomeraceae and Acaulosporaceae families, specifically the genera Glomus and Acaulospora in ASS soil. Further exploration is required to better understand their role in promoting plant growth under adverse conditions. The study highlights the significance of cutting-edge sequencing tools in advancing the comprehension of essential symbiotic relationships for sustainable agriculture in challenging environments.

“…These ASVs were identified as VTX00024. VTX00024 is usually present in the roots of woody plants and has tolerance to various environments, including semi-arid and saline-alkaline conditions (Kaidzu et al, 2020). VTX00024 is also found in upland rice and is supposed to adapt to low nutrient conditions (Ibne Baki et al, 2021).…”
