“…Endophytes in these leaves also pass through this boundary with the dying of leaf. Endophytes were known as the member of symbiosis ecosystem over the past few decades, but now they are found to play an important role in terrestrial decomposition process (Müller et al, 2001;Kumaresan and Suryanarayanan, 2002;Osono et al, 2004;Sun et al, 2011;Peršoh et al, 2013). In this study, dominant endophytes, as pioneer colonizers, were inoculated onto surface-sterilized leaves before litter decomposition in order to mimic the natural process.…”

“…What is the fate of the endophytes after their hosts died, which has made the ecologists to be lost in thought for very long time, and encourages the ecologists to pay close attention to this field. Many endophytes had been found as pioneer colonizers in litter decomposition (Müller et al, 2001;Kumaresan and Suryanarayanan, 2002;Osono, 2003Osono, , 2006Korkama-Rajala et al, 2008;Fukasawa et al, 2009;He et al, 2012;Peršoh et al, 2013;Unterseher et al, 2013;Vo ríšková and Baldrian, 2013), and they had also often been found in the litter layer (Mitchell et al, 1978;Livsey and Barklund, 1992;Lindahl et al, 2007;Unterseher et al, 2013). Endophytic fungi can take the priority over other saprophytic fungi from the beginning of litter decomposition by colonizing plant tissue when it is still living (Thormann et al, 2003).…”

“…As leaves senesce, epiphytic fungi can colonize the interior of leaves rapidly, leading to a subsequent decline in the relative abundance of endophytic taxa (Cabral, 1985; Stone, 1987; Osono, 2002; but see Peršoh et al, 2013). When we examine common OTU as a function of their abundance in leaves of each type, 35% have patterns of leaf-association that match that of ambient, non-endophytic fungi colonizing leaf interiors after leaf death (Fig.…”

“…Together, these studies speak to continuity between fungi that occur within living and non-living leaves (see also Promputtha et al, 2007; Chaverri & Gazis, 2011; Sun, Guo & Hyde, 2011; Peršoh et al, 2013; Voříšková & Baldrian, 2013; Unterseher, Peršoh & Schnittler, 2013). However, it is not clear whether such continuity is consistent in the distinctive plant and fungal communities present in different biomes, nor whether patterns of persistence vary among phylogenetically diverse plants.…”

“…For example, fungal genotypes that were dominant in the phyllosphere of living leaves of Quercus petraea disappeared by two to four months post abscission (Voříšková & Baldrian, 2013). Similarly, fungal communities in living leaves of European beech ( Fagus sylvatica ) in autumn differed from fungi inhabiting leaf litter and bark in the following spring (Unterseher, Peršoh & Schnittler, 2013; but see Peršoh et al, 2013). …”

Diversity, taxonomic composition, and functional aspects of fungal communities in living, senesced, and fallen leaves at five sites across North America

BackgroundFungal endophytes inhabit symptomless, living tissues of all major plant lineages to form one of earth’s most prevalent groups of symbionts. Many reproduce from senesced and/or decomposing leaves and can produce extracellular leaf-degrading enzymes, blurring the line between symbiotrophy and saprotrophy. To better understand the endophyte–saprotroph continuum we compared fungal communities and functional traits of focal strains isolated from living leaves to those isolated from leaves after senescence and decomposition, with a focus on foliage of woody plants in five biogeographic provinces ranging from tundra to subtropical scrub forest.MethodsWe cultured fungi from the interior of surface-sterilized leaves that were living at the time of sampling (i.e., endophytes), leaves that were dead and were retained in plant canopies (dead leaf fungi, DLF), and fallen leaves (leaf litter fungi, LLF) from 3–4 species of woody plants in each of five sites in North America. Our sampling encompassed 18 plant species representing two families of Pinophyta and five families of Angiospermae. Diversity and composition of fungal communities within and among leaf life stages, hosts, and sites were compared using ITS-partial LSU rDNA data. We evaluated substrate use and enzyme activity by a subset of fungi isolated only from living tissues vs. fungi isolated only from non-living leaves.ResultsAcross the diverse biomes and plant taxa surveyed here, culturable fungi from living leaves were isolated less frequently and were less diverse than those isolated from non-living leaves. Fungal communities in living leaves also differed detectably in composition from communities in dead leaves and leaf litter within focal sites and host taxa, regardless of differential weighting of rare and abundant fungi. All focal isolates grew on cellulose, lignin, and pectin as sole carbon sources, but none displayed ligninolytic or pectinolytic activity in vitro. Cellulolytic activity differed among fungal classes. Within Dothideomycetes, activity differed significantly between fungi from living vs. non-living leaves, but such differences were not observed in Sordariomycetes.DiscussionAlthough some fungi with endophytic life stages clearly persist for periods of time in leaves after senescence and incorporation into leaf litter, our sampling across diverse biomes and host lineages detected consistent differences between fungal assemblages in living vs. non-living leaves, reflecting incursion by fungi from the leaf exterior after leaf death and as leaves begin to decompose. However, fungi found only in living leaves do not differ consistently in cellulolytic activity from those fungi detected thus far only in dead leaves. Future analyses should consider Basidiomycota in addition to the Ascomycota fungi evaluated here, and should explore more dimensions of functional traits and persistence to further define the endophytism-to-saprotrophy continuum.

Home‐field advantage in litter decomposition: A critical review from a microbial perspective

Litter decomposition is a key component of biogeochemical recycling. It is highly sensitive to changes in microbial community assembly. An interesting phenomenon in litter decomposition is the home-field advantage (HFA), where litter decomposes faster in native locations than in foreign sites. However, the role of the HFA in litter decomposition remains controversial. This review examines current evidence relating to the HFA using the leaf economics spectrum theory and the Lotka-Volterra niche competition model and explains its influence on the microbial assembly process. Here, it is proposed that the microbial community assembly could help to explain the HFA at spatiotemporal scales. This review improves understanding of the role of the succession of microbial communities in HFA litter decomposition and in the elemental cycle of forest systems.
