“…This explained that no significant correlation was observed between symbiotrophs/saprotrophs and soil nutrients (SOM, TN, and TP), while a variety of mycorrhizal/saprotrophic fungi participate in carbon, nitrogen, and phosphorus cycling (Fujimura and Egger, 2012). In contrast, TN had an important role in the soil fungal community, which was consistent with a previous large-scale research study (Cai et al, 2018;Schappe et al, 2020). In particular, pathotrophs are more susceptible to TN, which has been confirmed to be more inclined to the environment with enriched nutrients (Zhang et al, 2017a;Schappe et al, 2020).…”

However, the type of pathogen determines the different effects of nitrogen, which means that a high nitrogen supply may increase infection by obligate parasites or decrease infection by facultative parasites (Dordas, 2008).…”

Revegetation is regarded as an effective means to improve the ecological environment in deserts and profoundly influences the potential ecological functions of the soil fungal community. Therefore, Illumina high-throughput sequencing was performed to characterize the soil fungal diversity and community composition at two soil depths (0–10 cm and 10–20 cm) with four revegetation durations (natural grassland, half-mature, nearly mature, and mature Pinus. sylvestris var. mongolica plantations) in the Mu Us Sandy Land, China. The effects of soil properties on soil fungal communities were also examined to reveal the connection between fungal function and soil environment. The results indicated that 1) soil nutrient content and enzyme activity showed significant differences through the restoration durations, 2) there was no significant effect of soil depth on soil fungal diversity, while the Shannon diversity index of all fungal communities was significantly different among different revegetation durations, 3) compared with grassland, ectomycorrhizal fungi (notably, Inocybe, Tuber, and Calostoma) were abundant in plantations. The endophyte fungus Mortierella was among the top 10 genera in all soil samples and arbuscular mycorrhizal fungus Diversispora was the indicator genus of the grassland, and 4) catalase and total nitrogen were the main factors affecting fungal community composition and were closely related to saprotrophs and pathotrophs, respectively. This new information indicates the variation of soil fungal communities along revegetation durations and highlights the interaction between fungal functions and desert ecosystems.

“…Urbanová et al (2015) concluded, that ectomycorrhizal fungi are more strongly associated with tree composition than with soil properties, in contrast to saprotrophic fungi, which are more strongly correlated with soil properties. Schappe et al (2020) found similar relationships in tropical rainforests in Panama.…”

Deep Soil Layers of Drought-Exposed Forests Harbor Poorly Known Bacterial and Fungal Communities

Soil microorganisms such as bacteria and fungi play important roles in the biogeochemical cycling of soil nutrients, because they act as decomposers or are mutualistic or antagonistic symbionts, thereby influencing plant growth and health. In the present study, we investigated the vertical distribution of the soil microbiome to a depth of 2 m in Swiss drought-exposed forests of European beech and oaks on calcareous bedrock. We aimed to disentangle the effects of soil depth, tree (beech, oak), and substrate (soil, roots) on microbial abundance, diversity, and community structure. With increasing soil depth, organic carbon, nitrogen, and clay content decreased significantly. Similarly, fine root biomass, microbial biomass (DNA content, fungal abundance), and microbial alpha-diversity decreased and were consequently significantly related to these physicochemical parameters. In contrast, bacterial abundance tended to increase with soil depth, and the bacteria to fungi ratio increased significantly with greater depth. Tree species was only significantly related to the fungal Shannon index but not to the bacterial Shannon index. Microbial community analyses revealed that bacterial and fungal communities varied significantly across the soil layers, more strongly for bacteria than for fungi. Both communities were also significantly affected by tree species and substrate. In deep soil layers, poorly known bacterial taxa from Nitrospirae, Chloroflexi, Rokubacteria, Gemmatimonadetes, Firmicutes and GAL 15 were overrepresented. Furthermore, archaeal phyla such as Thaumarchaeota and Euryarchaeota were more abundant in subsoils than topsoils. Fungal taxa that were predominantly found in deep soil layers belong to the ectomycorrhizal Boletus luridus and Hydnum vesterholtii. Both taxa are reported for the first time in such deep soil layers. Saprotrophic fungal taxa predominantly recorded in deep soil layers were unknown species of Xylaria. Finally, our results show that the microbial community structure found in fine roots was well represented in the bulk soil. Overall, we recorded poorly known bacterial and archaeal phyla, as well as ectomycorrhizal fungi that were not previously known to colonize deep soil layers. Our study contributes to an integrated perspective on the vertical distribution of the soil microbiome at a fine spatial scale in drought-exposed forests.

“…Though there are many fungal lifestyles and interkingdom interactions, the commonly distinguished guilds encompass pathotrophs, saprotrophs, symbiotrophs, taxa capable of different lifestyles and a majority with yet unknown functional classification (Nguyen et al, 2016;Rai & Agarkar, 2016;Zellinger et al, 2016). Each of these guilds reacts differently to biotic and abiotic stimuli due to distinct nutrient acquisition strategies and can therefore be expected to also be affected by varying ecological factors (Schappe et al, 2020). Since trees are foundation species in forest ecosystems, their main traits directly affect symbiotrophic and pathotrophic fungal communities, and indirectly also saprotrophs through their dead organic matter input that regulates quantity and quality of substrates used by this functional group (Alberti et al, 2017;Purahong et al, 2017;Roy-Bolduc et al, 2016;Urbanová et al, 2015).…”
