“…Russula was also found to be a keystone taxa in the HKF network. Russula was found to be one of the most essential and abundant ECM fungi having a symbiotic relationship with diverse higher plants in the mountain rain forest, which conforms to the ndings of previous studies [22][23][24][25]. These keystone taxa in HKF play essential roles in the fungal communities of the soil environment.…”

Background The Abies koreana (Korean fir) population is declining at an accelerating rate on Mt. Hallasan in Jeju Island, Republic of Korea. Several prior studies have reported various inconclusive reasons, indicating that additional data, such as data on microbial communities that promote plant growth and resistance to abiotic stresses, are required to further understand the phenomena. To the best of our knowledge, this is the first investigation that documents the changes in the microbial community as the result of the decline of the Korean fir forest. Here, high throughput sequencing data were provided for the rhizosphere microbiome of a Korean fir, identifying the bacterial and fungal composition differences between the rhizosphere soil of healthy Korean fir (HKF) and dead Korean fir (DKF). Results The results showed that the DKF soil of the fungal community was distinctly separated from the HKF soil. Interestingly, HKF soil comprised dominant symbiotic fungi (Russula, Sebacina, Inocybe, and Phenoliferia), whereas the microbial composition in DKF samples comprised abundant saprotrophs, such as Trichoderma, Ascocoryne, and Umbelopsis. It was also observed that symbiotic fungi, such as Russula, act as a hub in the co-occurrence network. Additionally, the representative fungal genera in HKF soil had a strong positive correlation with only a few soil physicochemical features: K+, Na+, Avail P, and cation exchange capacity (CEC). Conclusions Our findings shed light on the rhizosphere microbiota of dead and live A. koreana plants and their relationship with edaphic factors. The woody plant-associated symbiotic fungi, including ECMs, was also highlighted as a potential strategy to enhance the Korean fir forest ecosystem health.

“…( Rudawska et al, 2016 ). Besides the already listed genera, members of the genera Clavulina , Elaphomyces , Amanita , Boletus , Sebacina and Tylospora were already found to be associated and typical in silver fir stands ( Comandini et al, 1998 ; Wazny, 2014 ; Rudawska et al, 2016 ; Arguelles-Moyao et al, 2017 ; Ważny and Kowalski, 2017 ). Yet their exact role in framing the plant partner phenology remains unexplored.…”

Root-Associated Fungal Communities From Two Phenologically Contrasting Silver Fir (Abies alba Mill.) Groups of Trees

Root-associated fungal communities are important components in ecosystem processes, impacting plant growth and vigor by influencing the quality, direction, and flow of nutrients and water between plants and fungi. Linkages of plant phenological characteristics with belowground root-associated fungal communities have rarely been investigated, and thus our aim was to search for an interplay between contrasting phenology of host ectomycorrhizal trees from the same location and root-associated fungal communities (ectomycorrhizal, endophytic, saprotrophic and pathogenic root-associated fungi) in young and in adult silver fir trees. The study was performed in a managed silver fir forest site. Twenty-four soil samples collected under two phenologically contrasting silver fir groups were analyzed for differences in root-associated fungal communities using Illumina sequencing of a total root-associated fungal community. Significant differences in beta diversity and in mean alpha diversity were confirmed for overall community of ectomycorrhizal root-associated fungi, whereas for ecologically different non-ectomycorrhizal root-associated fungal communities the differences were significant only for beta diversity and not for mean alpha diversity. At genus level root-associated fungal communities differed significantly between early and late flushing young and adult silver fir trees. We discuss the interactions through which the phenology of host plants either drives or is driven by the root-associated fungal communities in conditions of a sustainably co-naturally managed silver fir forest.

“…The shift in EcM community associated with growth stages for South American Nothofagaceae forests has not yet been elucidated, nor the effects of site conditions or anthropogenic impacts. It has been reported that seedlings could present a reduced diversity of EcM communities compared to mature stands (Ważny and Kowalski, 2017), that some EcM species can be present at any stage of ecosystem development (Matsuda and Hijii, 2004;Twieg et al, 2007), while others has high association with seedling stages (Cline et al, 2005;Ważny and Kowalski, 2017). All these considerations should be taken in account to select candidate species for inoculation programs.…”

The southernmost portion of the Andes in South America hosts Nothofagaceae forests that form ectomycorrhizal (EcM) associations. We compiled all the published reports of EcM taxa from these woodlands, based on fruit-body collections and molecularly identified root tips. This resulted in 87 peer-reviewed research papers dealing with EcM associations from Nothofagaceae forests published over the past 62 years. Based on these papers the EcM richness and its association with Nothofagaceae species was analyzed. Represented by 45 genera (34 Basidiomycetes and 11 Ascomycetes), 479 EcM taxa have been recorded, plus an additional 46 EcM taxa which are potentially EcM. Cortinarius was the most frequent and diverse genus, with 64.9% of total species. Nothofagus dombeyi had the highest number of unique EcM species, followed by N. pumilio, N. antarctica and Lophozonia obliqua. The EcM community associated with Nothofagus species, except N. nitida, showed higher similarities among themselves, than with Lophozonia and Fuscospora species. Beta diversity indexes showed EcM Nothofagus species have 29–42% niche overlap, while Nothofagus—Lophozonia only had 1–16%. The assessment of the accuracy of the EcM diversity, host specificity and community structure deserve further studies combining phylogenetic analysis based on broad ecological surveys. On the basis of pre-selected criteria Austropaxillus statuum, Cortinarius fragilis, Cortinarius xiphidipus and Hallingea purpurea are proposed as candidates for nursery spore inoculations, and should be subject to scientific evaluation to determine costs and benefits.
