“…Comparisons between the herein recovered fungal diversity and that obtained in other works are difficult due to the relative scarcity of similar samplings. In general terms, we cannot conclude that the fungal community reported here is highly divergent from that found in other studies (e.g., [16,[42][43][44]). Most fungi identified are common endophytes and soil dwellers, albeit, in other cases, BLAST identities matched uncultured fungi, indicating a possible novelty in the strains.…”

“…Most of them could be classified within the Pleosporales, as found in previous surveys in Mediterranean [43,44] or semiarid areas [9,[46][47][48][49]. DSF were also abundant within the root tissues, especially along the longitudinal root axis, and appeared tightly associated to the vascular system as previously observed by [9], who postulated that this demand an active participation in a mutualistic relationship with the host.…”

Fungal Assemblages Associated with Roots of Halophytic and Non-halophytic Plant Species Vary Differentially Along a Salinity Gradient

Structure of fungal communities is known to be influenced by host plants and environmental conditions. However, in most cases, the dynamics of these variation patterns are poorly understood. In this work, we compared richness, diversity, and composition between assemblages of endophytic and rhizospheric fungi associated to roots of two plants with different lifestyles: the halophyte Inula crithmoides and the non-halophyte I. viscosa (syn. Dittrichia viscosa L.), along a spatially short salinity gradient. Roots and rhizospheric soil from these plants were collected at three points between a salt marsh and a sand dune, and fungi were isolated and characterized by ITS rDNA sequencing. Isolates were classified in a total of 90 operational taxonomic units (OTUs), belonging to 17 fungal orders within Ascomycota and Basidiomycota. Species composition of endophytic and soil communities significantly differed across samples. Endophyte communities of I. crithmoides and I. viscosa were only similar in the intermediate zone between the salt marsh and the dune, and while the latter displayed a single, generalist association of endophytes, I. crithmoides harbored different assemblages along the gradient, adapted to the specific soil conditions. In the lower salt marsh, root assemblages were strongly dominated by a single dark septate sterile fungus, also prevalent in other neighboring salt marshes. Interestingly, although its occurrence was positively correlated to soil salinity, in vitro assays revealed a strong inhibition of its growth by salts. Our results suggest that host lifestyle and soil characteristics have a strong effect on endophytic fungi and that environmental stress may entail tight plant-fungus relationships for adaptation to unfavorable conditions.

“…DSE fungi belong to a wide range of different ascomycetes. This is reflected by the diverse spectrum of the biology of DSE (Girlanda et al 2006) and may help to explain why the knowledge of their ecology is still scanty. It is clear, that typical DSE like Phialocephala fortinii Wang & Wilcox can promote plant growth.…”

“…Very little information exists on the abundance, habitat or host preferences of endophytic fungi, and about the ecological importance of these associations in Mediterranean environments (GIRLANDA et al, 2006). This is especially true for the Iberian Peninsula, in comparison with other biogeographical regions.…”
