“…Our results also indicate a strong difference between the fungal communities of leaves and twigs as they not only had a significantly different richness and diversity (Table 1) types was previously reported from many woody species (Liu et al, 2015;Martin, Gazis, Skaltsas, Chaverri, & Hibbett, 2015;Martins et al, 2016;Sun et al, 2012). These reports indicate that along with different biochemical properties of each organ, the higher possibility of the horizontal transmission of endophytes caused by the longer lifetime of twigs might be the reason for the observed differences between the fungal endophytes richness and diversity of leaves and twigs.…”

“…For example, 22 fungal endophytes were isolated from Q. cerris and Q. pubescens (Moricca, Ginetti, & Ragazzi, 2012), 19 were isolated from Q. suber (Linaldeddu, Sirca, Spano, & Franceschini, 2011), and 25 endophytes were isolated from herbaceous and woody organs of Q. robur (Gonthier, Gennaro, & Nicolotti, 2006). Most of the isolated fungal endophytes in this study belonged to Ascomycetes, as did the fungal endophytes of different woody plants (Martins, Pereira, Bota, Bento, & Baptista, 2016;Yadav, Yadav, Kumar, & Yadav, 2016) as well as other oak species (Linaldeddu et al, 2011;Ragazzi et al, 2001;Ragazzi, Moricca, Capretti, Dellavalle, & Turco, 2003), investigated in many previous studies. Sordariomycetes were the dominant class (Moricca et al, 2012).…”

“…Sampling sites did not have any significant effects on Hill's series of diversity and only affected the isolation rate. The spatial variations and temporal dynamics of endophytic fungal communities have been studied frequently in the past few years (Martins et al, 2016;Mishra et al, 2012;Scholtysik, Unterseher, Otto, & Wirth, 2013). In this case, studied sites had similar forest structure, elevation range and climate which possibly led to relatively similar fungal communities in Q. brantii organs with similar diversity (Figure 3b).…”

Culture‐based methods using low‐temperature incubation revealed cold‐adapted fungal endophytes from semiarid forests

Fungal endophytes are an important part of the plant microbiome and participate in maintaining the stability of ecosystems. Culture‐based methods are frequently considered in studying fungal communities because of their advantages in providing cultures for further experiments and their low cost. In comparison with next‐generation sequencing methods, their ability to assess fungal diversity is questionable. Here, we show how using two different incubation temperatures can improve the yield of fungal endophytes by culture‐based methods. Diversity, organ preference and spatiotemporal variability of endophytic fungal communities living within Quercus brantii L. were investigated using two different incubation temperatures. To test the effects of using low‐temperature incubation on diversity estimations, twigs and leaves of Quercus brantii were incubated under 25°C and 4°C conditions. Isolation rate and Hill's series of diversity were calculated for each sample. Model‐based analysis was used to evaluate the effects of (a) incubation temperature, (b) organ type and (c) spatiotemporal variations on fungal isolation rate, fungal diversity and community composition. Our results showed a strong organ specificity and temporal dynamics among endophytic fungal communities, but the location of the forest stand had only a limited effect on fungal community composition. Low‐temperature incubation enabled us to improve culture‐based methods by discovering the diversity of cold‐adapted fungal endophytes and a significantly different part of the endophytic communities that is usually missed by customary culturing temperature. The isolation of cold‐adapted endophytes from a semiarid environment opens a new window to further studies on this kind of fungi in such ecosystems.

“…In another study, endophytic fungi from the phyllosphere and roots of olive cultivar (cv.) Cobrançosa 20 were screened by a culture-dependent method to compare the fungal communities between above- and belowground compartments. Microbial communities of the olive phyllosphere and carposphere have been analyzed using denaturing gradient gel electrophoresis (DGGE) 21 , isolation of fungi in culturing media 22 and high-throughput sequencing of both fungal 23 and prokaryotic 24 communities.…”

Up to date, the bacterial and fungal microbial communities from the olive (Olea europaea L.) root systems have not been simultaneously studied. In this work, we show that microbial communities from the olive root endosphere are less diverse than those from the rhizosphere. But more relevant was to unveil that olive belowground communities are mainly shaped by the genotype of the cultivar when growing under the same environmental, pedological and agronomic conditions. Furthermore, Actinophytocola, Streptomyces and Pseudonocardia are the most abundant bacterial genera in the olive root endosphere, Actinophytocola being the most prevalent genus by far. In contrast, Gp6, Gp4, Rhizobium and Sphingomonas are the main genera in the olive rhizosphere. Canalisporium, Aspergillus, Minimelanolocus and Macrophomina are the main fungal genera present in the olive root system. Interestingly enough, a high proportion of so far unclassified fungal sequences at class level were detected in the rhizosphere. From the belowground microbial profiles here reported, it can be concluded that the genus Actinophytocola may play an important role in olive adaptation to environmental stresses. Moreover, the huge unknown fungal diversity suggests that there are still some fungi with important ecological and biotechnological implications that have yet to be discovered.
