“…Examples of endophytes isolated from various bryophytes are summarized in Table 1 . Fungal endophytes are commonly isolated from mosses [ 40 , 41 , 42 , 43 , 44 ]. Neslon [ 45 ] performed an extensive study of fungal endophytes from the liverwort Marchantia polymorpha and observed the presence of at least 45 species belonging to the ascomycete classes Dothideomycetes, Leotiomycetes, Pezizomycetes, Saccharomycetes, and Sordariomycetes.…”

Bioactive Compounds Produced by Endophytic Microorganisms Associated with Bryophytes—The “Bryendophytes”

The mutualistic coexistence between the host and endophyte is diverse and complex, including host growth regulation, the exchange of substances like nutrients or biostimulants, and protection from microbial or herbivore attack. The latter is commonly associated with the production by endophytes of bioactive natural products, which also possess multiple activities, including antibacterial, insecticidal, antioxidant, antitumor, and antidiabetic properties, making them interesting and valuable model substances for future development into drugs. The endophytes of higher plants have been extensively studied, but there is a dearth of information on the biodiversity of endophytic microorganisms associated with bryophytes and, more importantly, their bioactive metabolites. For the first time, we name bryophyte endophytes “bryendophytes” to elaborate on this important and productive source of biota. In this review, we summarize the current knowledge on the diversity of compounds produced by endophytes, emphasizing bioactive molecules from bryendophytes. Moreover, the isolation methods and biodiversity of bryendophytes from mosses, liverworts, and hornworts are described.

“…For the better part of a decade, closing the knowledge gap between uncultured and cultured fungi has been a focus for ecologists and taxonomists, especially those working on endophytes or mycorrhizal fungi symbiotic with plants (e.g., Arnold et al, 2021 ; Tanney & Seifert, 2018 ). Our coordinated microbiological and HTS surveys in the built environment yielded thousands of fungal strains, many of them now accessioned in culture collections.…”

A new species of the yeast genus Blastobotrys was discovered during a worldwide survey of culturable xerophilic fungi in house dust. Several culture-dependent and independent studies from around the world detected the same species from a wide range of substrates including indoor air, cave wall paintings, bats, mummies, and the iconic self-portrait of Leonardo da Vinci from ca 1512. However, none of these studies identified their strains, clones, or OTUs as Blastobotrys. We introduce the new species as Blastobotrys davincii f.a., sp. nov. (holotype CBS H-24879) and delineate it from other species using morphological, phylogenetic, and physiological characters. The new species of asexually (anamorphic) budding yeast is classified in Trichomonascaceae and forms a clade along with its associated sexual state genus Trichomonascus. Despite the decade-old requirement to use a single generic name for fungi, both names are still used. Selection of the preferred name awaits a formal nomenclatural proposal. We present arguments for adopting Blastobotrys over Trichomonascus and introduce four new combinations as Blastobotrys allociferrii (≡ Candida allociferrii), B. fungorum (≡ Sporothrix fungorum), B. mucifer (≡ Candida mucifera), and Blastobotrys vanleenenianus (≡ Trichomonascus vanleenenianus). We provide a nomenclatural review and an accepted species list for the 37 accepted species in the Blastobotrys/Trichomonascus clade. Finally, we discuss the identity of the DNA clones detected on the da Vinci portrait, and the importance of using appropriate media to isolate xerophilic or halophilic fungi.

“…The relative abundance of three yeast ASVs of Coniochaeta in strawberry root decreased with increasing reused coir age. Coniochaeta endophytes of plants and lichens (Damm et al, 2010;Arnold et al, 2021a, Arnold et al, 2021b are positively associated with soil health (Huang et al, 2020).…”

In the UK, strawberry is mostly grown in coconut coir substrate under protection. Coir substrate is usually used only for one or two cropping seasons because the continuous reuse of coir without any treatment leads to yield decline. In this study, we investigated the changes in bacterial and fungal communities in strawberry roots and bulk coir in relation to (i) the coir substrate age (cropping seasons) and (ii) oak or beech biochar amendment at planting. Coir age did not affect fungal/bacterial alpha (within-sample) diversity but affected beta (between-sample) diversity. Amendment with either oak or beech biochar did not lead to significant changes in either alpha or beta diversity for both fungi and bacteria, but it did alter the relative abundance of 13 fungal ASVs. This study identified six bacterial and 20 fungal ASVs with a significant positive linear relationship with coir age and also eight bacterial and 22 fungal ASVs with a significant negative linear relationship with coir age. Notably, the observed strawberry yield decline in reused coir substrate could be associated with a generalist root pathogen, Ilyonectria destructans (ex. Cylindrocarpon destructans), of which the abundance increased annually by 225% and 426% in strawberry root and bulk coir, respectively. Future research is needed to confirm the role of I. destructans in reused coir on strawberry plant health and fruit productivity and then to identify management strategies for yield decline mitigation.
