“…The endophytic P. sporulosa F03 strain was isolated from the leaves of the P. planifolius , which were collected from Serra do Cipó – Minas Gerais, Brazil, as described in a previous work 10 . The fungus was identified through ITS sequencing analysis; the nucleotide sequence determined was deposited in the GenBank database under the access number JX496114.1 10 . The strain was stored in sterile water at 25 °C and deposited at the NuBBE fungi collection site in Araraquara – São Paulo, Brazil, under the access number F03.…”

“…In our previous study, the chemical investigation of the endophytic fungus Paraphaeosphaeria sporulosa F03, isolated from Paepalanthus planifolius (Bong) Körn (Eriocaulaceae), led to the identification of new antifungal benzopyran and benzaldehyde derivatives 10 . In that study, the extract of P. sporulosa cultivated in potato dextrose broth (PDB) medium was analyzed by UHPLC-HRMS/MS along with the active fractions Fr.J2 to Fr.J4 obtained from the first fractionation procedure.…”

As part of our continuing efforts to discover new bioactive compounds from endophytic fungal sources, we have investigated the extract of the Paraphaeosphaeria sporulosa F03 strain. The study led to the isolation of four new 3-methyl-isoquinoline alkaloids (1 – 4) and four known polyketides (5 – 8). The structures of compounds 1 – 4 were elucidated by 1D and 2D NMR experiments and HRMS analysis. The absolute configuration of 4 was determined by comparison of its experimental electronic circular dichroism spectrum with calculated data. Compounds 1 – 4 exhibited antifungal activity with minimal inhibitory concentration values ranging from 6.25 – 50 µg/mL against six Candida species but they did not present any cytotoxic activity against the human tumor cell lines A549 (lung), MCF-7 (breast), and HepG2 (hepatocellular). In addition, compound 4 exhibited antiplasmodial activity in the low micromolar range (IC50 = 4 µM).

“…By contrast, endophytic and/or generalist pathogenic fungi were more common in 10-year-old wounds (Table 2). For example, in 10-year-old wounds, there were fungal endophytes such as S. cycadis and Paraphaeosphaeria sporulosa [63][64][65], and plant pathogens Neoleptosphaeria rubefaciens [66][67][68] and Sporocadus trimorphus [69] (Table 2), but their functional role in colonized oak wood is obscure.…”

We investigated fungal communities in oak wounds to determine how fungal species richness and community composition changes depending on the age of wounds. The sampling of wood cores was carried out from 10-, 20-, 30-, 40-, and 50-year-old wounds. The fungal community was analyzed using high-throughput sequencing of ITS2 rDNA. Sequence analysis showed the presence of 534 fungal OTUs, which were 83.4% Ascomycota, 16.3% Basidiomycota, and 0.3% Mucoromycota. The fungal OTU richness changed over time: it increased as compared between 10- and 20-year-old wounds, remained similar in 20- to 40-year-old wounds, and decreased in 50-year-old wounds. The fungal community composition also changed over time with the largest differences detected between 10-year-old and older wounds (p < 0.001). The most common representatives of Basidiomycota were Laetiporus sulphureus (34.7%), Mycena galericulata (17.0%), and Cylindrobasidium evolvens (6.5%), and the most common of Ascomycota were Aposphaeria corallinolutea (13.6%), Sclerostagonospora cycadis (7.6%), and Cadophora malorum (5.8%). In conclusion, oak wounds of different ages were colonized by a high diversity of fungi including oak-associated species. Fungal communities in oak wounds underwent qualitative and quantitative changes over time, which led to the gradual shift from fungal generalists in young wounds to oak specialists in older wounds.
