“…Among these, the major genera, such as Acaulospora , Archaeospora , Gigaspora , Glomus , Paraglomus , and Scutellospora , have been shown to form symbiotic structures with eucalypts [ 53 , 54 ]. Ambispora , Claroideoglomus , and Diversispora are also found in eucalypt plantations [ 55 , 56 ]. Most have studies confirmed the dominant position of Glomus in the AM fungal community in eucalyptus roots [ 57 , 58 ].…”

Eucalyptus roots form symbiotic relationships with arbuscular mycorrhizal (AM) fungi in soil to enhance adaptation in challenging environments. However, the evolution of the AM fungal community along a chronosequence of eucalypt plantations and its relationship with soil properties remain unclear. In this study, we evaluated the tree growth, soil properties, and root AM fungal colonization of Eucalyptus grandis W. Hill ex Maiden plantations at different ages, identified the AM fungal community composition by high-throughput sequencing, and developed a structural equation model among trees, soil, and AM fungi. Key findings include the following: (1) The total phosphorus (P) and total potassium (K) in the soil underwent an initial reduction followed by a rise with different stand ages. (2) The rate of AM colonization decreased first and then increased. (3) The composition of the AM fungal community changed significantly with different stand ages, but there was no significant change in diversity. (4) Paraglomus and Glomus were the dominant genera, accounting for 70.1% and 21.8% of the relative abundance, respectively. (5) The dominant genera were mainly influenced by soil P, the N content, and bulk density, but the main factors were different with stand ages. The results can provide a reference for fertilizer management and microbial formulation manufacture for eucalyptus plantations.

Arbuscular mycorrhizal fungi (AMF) are mycorrhizal from the endomycorrhizal group. The fungi live on higher plants' roots by performing symbiotic mutualism. This study aimed to identify AMF spores after trapping in corn roots and the degree of root infection by AMF in several host plants. The study was conducted using tidal swamps soil samples taken from Mulyasari Tanjung Lago Village, Banyuasin Regency, South Sumatra. The experiment used a randomized block design and three replicates with four host plants as a treatment: corn, soybean, sugarcane (monoculture) and sugarcane-soybean (combination). The results showed that AMF spores found on corn roots after trapping were from the <em>Acaulospora</em> sp. and <em>Glomus</em> sp. groups. Hyphae, vesicles, arbuscules and spores are AMF structures found in the roots of host plants infected by AMF. The percentage of AMF infection in host plant roots ranged from 1.11% to 77.44% where the highest was in maize host plant roots at 77.44% in the form of internal hyphae. The maize host plant has a high potential to be colonized by AMF compared to a mixture of soybean, sugarcane and sugarcane-soybean.

Fungi play vital regulatory roles in terrestrial ecosystems. Local community assembly mechanisms, including deterministic and stochastic processes, as well as the size of regional species pools (gamma diversity), typically influence overall soil microbial community beta diversity patterns. However, there is limited evidence supporting their direct and indirect effects on beta diversity of different soil fungal functional groups in forest ecosystems. To address this gap, we collected 1606 soil samples from a 25-ha subtropical forest plot in southern China. Our goal was to determine the direct effects and indirect effects of regional species pools on the beta diversity of soil fungi, specifically arbuscular mycorrhizal (AM), ectomycorrhizal (EcM), plant-pathogenic, and saprotrophic fungi. We quantified the effects of soil properties, mycorrhizal tree abundances, and topographical factors on soil fungal diversity. The beta diversity of plant-pathogenic fungi was predominantly influenced by the size of the species pool. In contrast, the beta diversity of EcM fungi was primarily driven indirectly through community assembly processes. Neither of them had significant effects on the beta diversity of AM and saprotrophic fungi. Our results highlight that the direct and indirect effects of species pools on the beta diversity of soil functional groups of fungi can significantly differ even within a relatively small area. They also demonstrate the independent and combined effects of various factors in regulating the diversities of soil functional groups of fungi. Consequently, it is crucial to study the fungal community not only as a whole but also by considering different functional groups within the community.
