“…We found that the AMF diversity was significantly increased under NT compared to conventional tillage. The results are in agreement with those of previous studies, in which NT versus conventional tillage markedly changed Chao 1, observed species, and PD_whole of AMF at elongation in a greenhouse experiment in Chile (Aguilera et al, 2021), a field experiment in north China (Hu et al, 2015), and a field experiment in Spain (Gu et al, 2020).…”

BackgroundTillage practices can substantially affect soil properties depending on crop stage. The interaction between tillage and crop growth on arbuscular mycorrhizal fungi (AMF) communities remains unclear. We investigated the interactions between four tillage treatments (CT: conventional tillage, RT: reduced tillage, NT: no tillage with mulch, and SS: subsoiling with mulch), maintained for 25 years, and two wheat growth stages (elongation stage and grain filling stage) on AMF diversity and community composition.ResultsThe AMF community composition strongly changed during wheat growth, mainly because of changes in the relative abundance of dominant genera Claroideoglomus, Funneliformi, Rhizophagu, Entrophospora, and Glomus. Co-occurrence network analysis revealed that the grain filling stage had a more complex network than the elongation stage. Redundancy analysis results showed that keystone genera respond mainly to changes in soil organic carbon during elongation stage, whereas the total nitrogen content affected the keystone genera during grain filling. Compared with CT, the treatments with mulch, i.e., NT and SS, significantly changed the AMF community composition. The change of AMF communities under different tillage practices depended on wheat biomass and soil nutrients. NT significantly increased the relative abundances of Glomus and Septoglomus, while RT significantly increased the relative abundance of Claroideoglomus.ConclusionOur findings indicate that the relative abundance of dominant genera changed during wheat growth stages. Proper tillage practices (e.g., NT and SS) benefit the long-term sustainable development of the Loess Plateau cropping systems.

“…Previously, other factors, such as soil phosphate availability and host species were identi ed as main determinant of the root AM fungal structure (Cavagnaro et al, 2005;Ehinger et al, 2009;Eom et al 2000;Helgason et al 2002;Vanderkoornhuyse et al 2003). Finally, the fact that two barley genotypes, Atomo and Atlante, in notinoculated and inoculated conditions, respectively, showed signi cant differences in the AM fungal community structure between growth stages, is in accordance with a previous work reporting differences along the plant cycle in bread wheat, oat and barley, inoculated and not with a AMF (Aguilera et al 2021). The importance of the phenological stage in shaping AM fungal community structure in roots of wheat was also reported in eld conditions (Marrassini et al 2024) and and perennial and annual grasses and non-grasses species (Lingfei et al 2005).…”

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.

“…In this sense, there are works to recover heritage varieties in order to use them as rootstocks ( Milla-Tapia et al, 2013 ; Franck et al, 2019 ). As a future trend is relevant to consider even though plantations have been slowly increasing in the southern regions, viticulture faces new limitations such as the production on Andisols, which are very acidic, phosphorus-fixing, and prone to induce aluminum (Al) toxicity ( Aguilera et al, 2017 , 2021a , b ).…”

The crop Vitis vinifera (L.) is of great economic importance as Chile is one of the main wine-producing countries, reaching a vineyard area of 145,000 ha. This vine crop is usually very sensitive to local condition changes and agronomic practices; therefore, strategies to counteract the expected future decrease in water level for agricultural irrigation, temperature increase, extreme water stress (abiotic stress), as well as increase in pathogenic diseases (biotic stress) related to climate change will be of vital importance for this crop. Studies carried out in recent years have suggested that arbuscular mycorrhizal fungi (AMF) can provide key ecosystem services to host plants, such as water uptake implementation and enhanced absorption of nutrients such as P and N, which are key factors for improving the nutritional status of the vine. AMF use in viticulture will contribute also to sustainable agronomic management and bioprotection against pathogens. Here we will present (1) the current status of grapevines in Chile, (2) the main problems in grapevines related to water stress and associated with climate change, (3) the importance of AMF to face water stress and pathogens, and (4) the application of AMF as a biotechnological and sustainable tool in vineyards.
