“…NGS is also applied in the identification of endophytic fungi. König et al [41] have evidenced that such taxa as Acremonium, Alternaria, Cladosporium, Epicoccum, and Penicillium inhabit many grass species. Bullington and Larkin [42] have shown that fungal endophytes affect the survival of trees and influence the severity of their diseases.…”

Endophytic microbiota plays a role not only in supplying plants with the basic nutrients indispensable for their growth, but also helps them in the mechanisms of adaptation to various environmental stresses (i.e., salinity, drought), which is important in the aspect of crop yields. From the agricultural and biotechnological points of view, the knowledge of endophytes and their roles in increasing crop yields, plant resistance to diseases, and helping to survive environmental stress is extremely desirable. This paper reviews some of the beneficial plant–microbe interactions that might be potentially used in both agriculture (plant growth stimulation effect, adaptation of host organisms in salinity and drought conditions, and support of defense mechanisms in plants), and in biotechnology (bioactive metabolites, application of endophytes for bioremediation and biotransformation processes, and production of biofertilizers and biopreparations). Importantly, relatively recent reports on endophytes from the last 10 years are summarized in this paper.

“…Similarly, differences between communities in relation to management at various disturbance levels ranging from undisturbed sites with light sheep grazing over intermediate (overgrazed) to disturbed sites (reseeded ryegrass lay) were observed in a study on culturable root-endophytic fungal communities in temperate grasslands [13]. By contrast, foliar fungal assemblages in Lolium perenne L. were not affected by land-use intensity (i.e., different levels of mowing, grazing and fertilization), though these assemblages did differ among study regions and season [14].…”

“…On the contrary, nitrogen addition had an impact on the overall community composition of fungi associated with shoots of three boreal moss species [16]. As most studies have focused on (culturable) root endophytes [14,15] or fungi belonging to the clavicipitaceous endophytes [17,18,19], it is still unknown how different management regimes affect the entire fungal endophyte community in plants, and in particular in the aerial parts of different grass species.…”

Fungal Endophyte Communities of Three Agricultural Important Grass Species Differ in Their Response Towards Management Regimes

Despite the importance of endophytic fungi for plant health, it remains unclear how these fungi are influenced by grassland management practices. Here, we investigated the effect of fertilizer application and mowing frequency on fungal endophyte communities and their life strategies in aerial tissues of three agriculturally important grass species (Dactylis glomerata L., Festuca rubra L. and Lolium perenne L.) over two consecutive years. Our results showed that the management practices influenced fungal communities in the plant holobiont, but observed effects differed between grass species and sampling year. Phylogenetic diversity of fungal endophytes in D. glomerata was significantly affected by mowing frequency in 2010, whereas fertilizer application and the interaction of fertilization with mowing frequency had a significant impact on community composition of L. perenne in 2010 and 2011, respectively. Taken together, our research provides a basis for future studies on responses of fungal endophytes towards management practices. To the best of our knowledge, this is the first study simultaneously assessing fungal endophyte communities in aerial parts of three agriculturally important grass species over two consecutive years.

“…Activity of plant compounds against other organisms may be a result of one major compound or a combination of diverse natural products. As just one example of potentially active natural products, phenolic acids are found in all plants, and some are nematicidal (López-Martínez et al, 2011). Phenols in root exudates can vary with endophyte status and cultivar (Guo et al, 2015).…”

Festulolium and fungal endophyte associations: host status for Meloidogyne incognita and nematotoxic plant extracts

Festulolium hybrids are forage grasses used worldwide in temperate climates. They are associated with the fungal endophyte Epichloë uncinata, which aids in nutrient uptake, drought tolerance, and production of metabolites that protect against parasites and herbivores. Epichloë uncinata produces loline alkaloids, which can deter insect pests. Festulolium has not been widely studied for susceptibility to plant-parasitic nematodes, so Festulolium lines, with and without fungal endophytes, were tested in the greenhouse for host status to the root-knot nematode Meloidogyne incognita. All were poor hosts, regardless of line or endophyte status. Pepper seedlings planted into soil following removal of the Festulolium plants were infected by nematodes, likely because of surviving nematodes from the original inoculation combined with some reproduction on Festulolium. Lolines were found in shoots and roots of all endophyteassociated lines, and some types of lolines in roots increased after nematode infection. Methanolic extracts from roots and shoots of a tested Festulolium line did not inhibit egg hatch, but killed nearly a third of second-stage juveniles whether an endophyte was present or not. Further studies would indicate whether these Festulolium lines aid in suppressing field populations of M. incognita.
