“…petiolata supports a relevant associated mycobiota with a high fungal biodiversity (64 taxa isolated). The fungal abundance and species richness recorded on this alga are comparable to those usually found on brown and red seaweeds, which are considered to be the richest in terms of fungal diversity [ 7 , 8 , 37 , 38 ]. The high number of taxa recorded is certainly due to the isolation procedure, which allowed the isolation of many species never recorded before in the Mediterranean Sea.…”

“…Algae represent an important isolation source of marine fungi with almost one-third of all known marine fungal species associated with these organisms [ 2 , 6 ]. Algae-inhabiting fungi represent a taxonomically diverse group of mutualists, endosymbionts, parasites, pathogens and saprobes, which are of evolutionary, ecological and economical interest [ 7 , 8 ]. A number of studies have demonstrated that algae-inhabiting fungi were responsible for the production of many bioactive secondary metabolites, previously attributed to the host [ 9 , 10 ].…”

The culturable mycobiota of Flabellia petiolata: First survey of marine fungi associated to a Mediterranean green alga

et al. 2017

Algae-inhabiting marine fungi represent a taxonomically and ecologically interesting group of microorganisms still largely neglected, especially in temperate regions. The aim of this study was to isolate and to identify the culturable mycobiota associated with Flabellia petiolata, a green alga frequently retrieved in the Mediterranean basin. Twenty algal thalli were collected from two different sampling sites in the Mediterranean Sea (Elba Island, Italy). A polyphasic approach showed the presence of a relevant alga-associated mycobiota with 64 taxa identified. The fungal isolates belonged mainly to Ascomycota (61 taxa), while only three Basidiomycota were detected. The phylogenetic position of sterile mycelia and cryptic taxa, inferred on the basis of LSU partial region, highlighted the presence of putative new phylogenetic lineages within Dothideomycetes and Sordariomycetes. This work represents the first quali-quantitative analysis of the culturable mycobiota associated to a green alga in the Mediterranean Sea.

“…Arbuscular mycorrhizal (AM) fungi are restricted to the Glomeromycotina, and ectomycorrhizal (ECM) fungi are primarily Agaricomycetes (Basidiomycota) 5 . In turn, every species of embryophyte and aquatic macroalgae sampled so far hosts PPF and EF 1,6,7 . The same is true for AL thalli (especially their microalgae and cyanobacteria), which host diverse ELF and lichenicolous fungi 2 .…”

Contemporaneous radiations of fungi and plants linked to symbiosis

et al. 2018

Interactions between fungi and plants, including parasitism, mutualism, and saprotrophy, have been invoked as key to their respective macroevolutionary success. Here we evaluate the origins of plant-fungal symbioses and saprotrophy using a time-calibrated phylogenetic framework that reveals linked and drastic shifts in diversification rates of each kingdom. Fungal colonization of land was associated with at least two origins of terrestrial green algae and preceded embryophytes (as evidenced by losses of fungal flagellum, ca. 720 Ma), likely facilitating terrestriality through endomycorrhizal and possibly endophytic symbioses. The largest radiation of fungi (Leotiomyceta), the origin of arbuscular mycorrhizae, and the diversification of extant embryophytes occurred ca. 480 Ma. This was followed by the origin of extant lichens. Saprotrophic mushrooms diversified in the Late Paleozoic as forests of seed plants started to dominate the landscape. The subsequent diversification and explosive radiation of Agaricomycetes, and eventually of ectomycorrhizal mushrooms, were associated with the evolution of Pinaceae in the Mesozoic, and establishment of angiosperm-dominated biomes in the Cretaceous.

“…Fusarium are cosmopolitan fungi, inhabiting all ecological niches, with the main reservoir being soil. The genus contains typical saprotrophs, endosymbionts and polyphages of crop and decorative plants and trees, as well as increasingly occurring human and animal pathogens [18,28,29]. The biologically active substances produced by Fusarium are often toxic and, thus, undesirable in agriculture and industry [29,30].…”

Houseplants for centuries have served people as the adornment of house, garden or public places, and are classified into two groups: blooming and foliage plants. They provide aesthetic and soothing value, thus should be free from disease and damage caused by phytophages [1]. It has been also proved that pot plants improve physicochemical conditions of the household by increasing the humidification of the air, which lowers air temperature and cleanses it from harmful substances released from carpets or wallpapers. Such plants are also known for their ability to reduce noise [2,3]. Some common houseplants are beneficial for health as they produce oxygen and remove toxic compounds like benzene, formaldehyde or trichloroethylene from the air [4]. Thus, indoor plant care is recommended in houses and office space due to plant air-cleaning
