“…On the surface of olive tree leaves and twigs, the composition of fungal communities was completely different from that in internal olive tissues. In previous studies, the same pattern was observed in leaves [13,15] and stems [33] of other plant species. Epiphytic community was dominated by fungal species with melanized hyphae/spores belonging to the families Davidiellaceae (mostly Cladosporium spp.…”

“…However, the implications of such differences have not yet been properly explored. In our study, epiphytic community was found to be significantly richer and more abundant than endophytic community, as described for the phyllosphere of other woody plant systems [14,15,33]. On the surface of olive tree leaves and twigs, the composition of fungal communities was completely different from that in internal olive tissues.…”

Endophytic and Epiphytic Phyllosphere Fungal Communities Are Shaped by Different Environmental Factors in a Mediterranean Ecosystem

The diversity and factors influencing fungal assemblages in phyllosphere of Mediterranean tree species have been barely studied, especially when endophytic and epiphytic communities are simultaneously considered. In this work, the endophytic and epiphytic fungal communities from olive tree phyllosphere were studied. This tree species is natural from the Mediterranean region and adapted to grow under adverse climatic conditions. The main objectives were to determine whether there are differences between both fungal communities and to examine whether different abiotic (climate-related) and biotic (plant organs) factors play a pivotal role in structuring these communities. Both communities differed in size and composition, with epiphytic community being richer and more abundant, displaying also a dominance of melanized fungi. Season was the major driver of community composition, especially of epiphytes. Other drivers shaping epiphytes were wind speed and temperature, while plant organ, rainfall, and temperature were the major drivers for endophytic composition. In contrast, canopy orientation caused slight variations in community composition of fungi, but with distinct effects in spring and autumn seasons. In conclusion, epiphytic and endophytic communities are not driven by the same factors. Several sources of variation undergo complex interactions to form and maintain phyllosphere fungal community in Mediterranean climates. Climatic parameters have influence on these fungal communities, suggesting that they are likely to be affected by climate changes in a near future.

“…The most abundant ones are principally generalist species, such as Aureobasidium pullulans , Cladosporium sp. or Eppicoccum nigrum , which were already found as abundant in the microbiome of many species (Jumpponen & Jones, 2009; Zambell & White, 2015; Pinto & Gomes, 2016). This result confirms that many fungal species disperse through the atmosphere (Lindemann et al, 1982; Brown & Hovmøller, 2002; Bulgarelli et al, 2013).…”

BackgroundDispersal events between habitat patches in a landscape mosaic can structure ecological communities and influence the functioning of agrosystems. Here we investigated whether short-distance dispersal events between vineyard and forest patches shape foliar fungal communities. We hypothesized that these communities homogenize between habitats over the course of the growing season, particularly along habitat edges, because of aerial dispersal of spores.MethodsWe monitored the richness and composition of foliar and airborne fungal communities over the season, along transects perpendicular to edges between vineyard and forest patches, using Illumina sequencing of the Internal Transcribed Spacer 2 (ITS2) region.ResultsIn contrast to our expectation, foliar fungal communities in vineyards and forest patches increasingly differentiate over the growing season, even along habitat edges. Moreover, the richness of foliar fungal communities in grapevine drastically decreased over the growing season, in contrast to that of forest trees. The composition of airborne communities did not differ between habitats. The composition of oak foliar fungal communities change between forest edge and centre.DiscussionThese results suggest that dispersal events between habitat patches are not major drivers of foliar fungal communities at the landscape scale. Selective pressures exerted in each habitat by the host plant, the microclimate and the agricultural practices play a greater role, and might account for the differentiation of foliar fugal communities between habitats.

“…1). Differences between cultivatable epi-and endophytic assemblages (Santamaria and Bayman 2005;Osono 2008;Flessa and Rambold 2013;Zambell and White 2015) indicate that only part of the epiphytic fungi invades the leaves. This supports the idea that plants actively filter invading fungi (Vacher et al 2016) and explain why plants growing at the same location harbour different microbiomes (Espinosa-Garcia and Langenheim 1990;Peršoh 2013).…”

Transient leaf endophytes are the most active fungi in 1-year-old beech leaf litter

et al. 2017

The ecological significance of fungi occurring asymptomatically inside living plant leaves is poorly understood. Given the broad saprotrophic potential of many endophytic fungi, we hypothesized that they persist in decaying litter for an extended period of time after leaf abscission. Fungal assemblages were assessed by highthroughput sequencing in autumn leaves of beech (Fagus sylvatica) and in the corresponding leaf litter in 388 samples from 22 beech forest plots in three widely distant regions of Germany. A considerable proportion of the leafendophytic fungi was also found in 1-year-old litter. Cooccurrence networks revealed that the fungi formed unstructured assemblages inside the living leaves, rather than well-structured communities. Previously endophytic fungi constituted an integral part of the fungal litter community and were by far the most active fungi in 1-year-old litter. We therefore consider these endophytic occurrences to represent transient stages. Composition of the aboveground microbiome appears therefore to be closely connected to the process of litter decomposition. Considering the respective linked fungal habitat will facilitate predicting nutrient and carbon cycling and storage in forest ecosystems as well as elucidating the ecology of leaf microbiomes.
