“…As for their 4% of the annotated OTUs counts, they have the potential to have a noticeable impact on bee bread fermentation. Paraphaeosphaeria species are also usually plant endophytes [74]. However, finding it within bee bread is not a surprising fact, being already reported to be present within honey samples [75], as well as to be reported as a gut endosymbiont for other insect species [76].…”

Information about the fungal composition of bee bread, and the fermentation processes to which the fungi contribute significantly, is rather scarce or fragmentary. In this study, we performed an NGS-based metagenomics snapshot picture study of the fungal composition of bee bread in four locations in Bulgaria during the most active honeybee foraging period at the end of June 2020. The sampling locations were chosen to differ significantly in climatic conditions, landscape, and anthropogenic pressure, and the Illumina 2 × 250 paired-end reads platform was used for amplicon metagenomics study of the ITS2 region. We found that some of the already reported canonical beneficial core fungal species were present within the studied samples. However, some fungal genera such as Monilinia, Sclerotinia, Golovinomyces, Toxicocladosporium, Pseudopithomyces, Podosphaera and Septoriella were reported for the first time among the dominant genera for a honeybee related product. Anthropogenic pressure negatively influences the fungal composition of the bee bread in two different ways—urban/industrial pressure affects the presence of pathogenic species, while agricultural pressure is reflected in a decrease of the ratio of the beneficial fungi.

Medicinal plant microbiomes undergo selection due to secondary metabolite presence. Resident endophytic/epiphytic microorganisms directly influence plant’s bioactive compound synthesis. Hypothesizing low microbial diversity in Serjania erecta leaves, we assessed leaf colonization by epiphytic and endophytic fungi. Given its traditional medicinal importance, we estimated diversity in the endophytic fungal microbiome. Analyses included scanning electron microscopy (SEM), isolation of cultivable species, and metagenomics. Epiphytic fungi interacted with S. erecta leaf tissues, horizontally transmitted via stomata/trichome bases, expressing traits for nematode trapping. Cultivable endophytic fungi, known for phytopathogenic habits, didn’t induce dysbiosis symptoms. This study confirms low leaf microbiome diversity in S. erecta, with a tendency towards more fungal species, likely due to antibacterial secondary metabolite selection. The classification of Halicephalobus sp. sequence corroborated the presence of nematode eggs on the epidermal surface of S. erecta by SEM. In addition, we confirmed the presence of methanogenic archaea and a considerable number of methanotrophs of the genus Methylobacterium. The metagenomic study of endophytic fungi highlighted plant growth-promoting yeasts, mainly Malassezia, Leucosporidium, Meyerozyma, and Hannaella. Studying endophytic fungi and S. erecta microbiomes can elucidate their impact on beneficial bioactive compound production, on the other hand, it is possible that the bioactive compounds produced by this plant can recruit specific microorganisms, impacting the biological system.

Plants play a key role in the ecosystem, especially in interactions with other living beings, including endophytic fungi. These fungi have a remarkable ability to produce bioactive compounds that resemble those present in their host plants. In this context, this study aims to present an overview of research carried out in Brazil on the biotechnological potential of endophytic fungi isolated from plants present in different Brazilian biomes. To achieve this goal, exploratory research was conducted in online databases and in open access published articles. The results indicate a concentration of investigations on prospecting endophytic fungi with metabolic potential in the Cerrado, Caatinga and Pantanal biomes. These endophytic fungi have a vast potential for the production of biomolecules with diverse applications in biotechnological processes. Some of these fungi have the ability to produce metabolites with varied biological activities, including pharmacological properties, such as antitumor and antibiotics. However, it is important to note that these fungi are still poorly studied, and may be explored in relation to their potential for producing biomolecules.
