“…The proportion of potentially novel taxa was estimated to exceed 30% in temperate beech and Mediterranean xerophyll forests (Yurkov, Röhl, et al, ; Yurkov, Wehde, et al, ). The same holds true for a few other temperate forests (Mašínová et al, ; Mestre et al, ; Takashima et al, ) and is likely to be true for tropical biotopes.…”

Pioneering studies performed in the nineteenth century demonstrated that yeasts are present in below‐ground sources. Soils were regarded more as a reservoir for yeasts that reside in habitats above it. Later studies showed that yeast communities in soils are taxonomically diverse and different from those above‐ground. Soil yeasts possess extraordinary adaptations that allow them to survive in a wide range of environmental conditions. A few species are promising sources of yeast oils and have been used in agriculture as potential antagonists of soil‐borne plant pathogens or as plant growth promoters. Yeasts have been studied mainly in managed soils such as vineyards, orchards and agricultural fields, and to a lesser extent under forests and grasslands. Our knowledge of soil yeasts is further biased towards temperate and boreal forests, whereas data from Africa, the Americas and Asia are scarce. Although soil yeast communities are often species‐poor in a single sample, they are more diverse on the biotope level. Soil yeasts display pronounced endemism along with a surprisingly high proportion of currently unidentified species. However, like other soil inhabitants, yeasts are threatened by habitat alterations owing to anthropogenic activities such as agriculture, deforestation and urbanization. In view of the rapid decline of many natural habitats, the study of soil yeasts in undisturbed or low‐managed biotopes is extremely valuable. The purpose of this review is to encourage researchers, both biologists and soil scientists, to include soil yeasts in future studies.

“…They were mainly represented by the genera Solicoccozyma and Saitozyma. Previously, Solicoccozyma and Saitozyma were found to be the most abundant yeast genera in soils under different tree species (Mašínová et al, 2017). Yeasts are able to utilize degradation products of plant material, but they are not considered to be primary degraders (Botha, 2011); however, yeasts belonging to former genus Cryptococcus, such as Saitozyma and Solicoccozyma, exhibited endocellulase activity (Thongekkaew, Ikeda, Masaki, & Iefuji, 2008) and were shown to be able to degrade cellulose (Štursová, Žifčáková, Leigh, Burgess, & Baldrian, 2012), which is suggestive of their involvement in the decomposition of dead plant material.…”

Together with plants, soil microbial communities play an essential role in the development of stable ecosystems on degraded lands, such as postmining spoil heaps. Our study addressed concurrent development of the vegetation and soil fungal and bacterial communities in the course of primary succession in a brown coal mine spoil deposit area in the Czech Republic across a chronosequence spanning 54 years. During succession, the plant communities changed from sparse plants over grassland and shrubland into a forest, becoming substantially more diverse with time. Microbial biomass increased until the 21st year of ecosystem development and later decreased. Although there was a close association between fungi and vegetation, with fungi mirroring the differences in plant community assemblages, the development of the bacterial community was different. The early succession community in the barren nonvegetated soil largely differed from that in the older sites, especially in its high abundance of autotrophic and free‐living N2‐fixing bacteria. Later in succession, bacterial community changes were minor and reflected the chemical parameters of the soil, including pH, which also showed a minor change with time. Our results show that complex forest ecosystems developed over 54 years on the originally barren soil of the temperate zone and indicate an important role of bacteria in the initial stage of soil development. Although the arrival of vegetation affects substantially fungal as well as bacterial communities, it is mainly fungi that respond to the ongoing development of vegetation.

“…In addition, our confocal microscopy analyses revealed, for the first time, the presence of fungal aggregates within embryos of acorns of sessile oak, as well as a dense fungal colonization on internal surfaces of fruit walls. These endophytic fungal populations contained foliar pathogens of Fagaceae tree species, such as Mycosphaerella tassiana and Taphrina carpini (Schubert et al , 2007; Bacigálová, 1991), ubiquitous fungal species, such as Epicoccum nigrum (Andrews & Harris, 2000), and endophytic yeasts previously described in other fruits, such as Curvibasidium cygneicollum (Sampaio et al , 2004; Mašínová et al , 2017). Network inference analyses revealed a positive association between the foliar pathogen Taphrina carpini and the mycoparasite Cladosporium delicatulum , suggesting that mother trees do not only transmit pathogens but also pathogen antagonists.…”

Trees, as foundation species, play a pivotal role in the species interaction networks that constitute forest ecosystems. From the seed stage, they interact with microbial communities that affect their growth, health and fitness. Despite their eco-evolutionary importance, the processes shaping seed microbial communities in natural forests have received little attention.• To unravel these processes, we analyzed the microbial communities of seeds collected in populations of sessile oak (Quercus petraea) growing along elevation gradients. We focused on the fungal communities as this group includes seed pathogens. Ecological processes shaping the communities were quantified using joint species distribution models.• Fungi were present in all seed tissues, including the embryo. Fungal communities differed significantly among oak populations along the elevation gradients, and among mother trees within the same population. These maternal effects remained significant after seed fall, despite colonization by fungal species on the ground. Associations between tree pathogens and their antagonists were detected in the seeds.• Our results demonstrate that both maternal effects and environmental filtering shape seed microbial communities of sessile oak. They provide a starting point for future research aimed at identifying the seed extended phenotypic traits that influence seed dispersal and germination, and seedling survival and growth across environments.
