Megjegyzések:	To learn about the yeast biodiversity of Hungarian honeys and to isolate osmotolerant yeasts, fifteen different honey varieties, beeswax, and bee bread were purchased, and samples of another, but highly osmotic material, tree sap (cherry, sour cherry, and plum), were collected from the northeastern region of the country. In total, 60 yeast strains were isolated and their taxonomic positions were determined by barcode sequences using ITS1-NL4 primers. The honey products contained mostly Zygosaccharomyces and Starmerella species. In addition, Hanseniaspora uvarum, Rhodotorula mucilaginosa and diobovata, Sporobolomyces roseus, Filobasidium magnum, Naganishia sp., and Aureobasidium pullulans were also present in smaller numbers. In contrast, tree saps contained Metschnikowia and Pichia fermentas cells. Further results suggest that some of the yeasts in honey can only "survive", while others can propagate at high sugar levels, generally between 600 and 700 mg/g, with a predominance of fructose. Properties important for pathogenicity, such as invasive hyphae production, gelatin melting ability, and growth at 37 ?C, were also examined. Hanseniaspora uvarum and Pichia fermentans representatives seemed to be negative for gelatin hydrolysis, while the other strains were able to melt gelatin. Although some of the strains could produce hyphae-like structures at 25 ?C, none of them could grow at 37 ?C.

Megjegyzések:	The plant microbiome is an increasingly intensive research area, with significance in agriculture, general plant health, and production of bioactive natural products. Correlations between the fungal endophytic communities and plant chemistry can provide insight into these interactions, and suggest key contributors on both the chemistry and fungal side. In this study, roots of various horseradish (Armoracia rusticana L.) accessions grown under the same conditions were sampled in two consecutive years and chemically characterized using a quality controlled, untargeted metabolomics approach by LC-ESI-MS/MS. Sinigrin, gluconasturtiin, glucoiberin and glucobrassicin were also quantified. Thereafter, a subset of roots from 8 accessions (n = 64) with considerable chemical variability was assessed for their endophytic fungal community, using an ITS2 amplicon-based metagenomic approach using a custom primer with high coverage on fungi, but no amplification of host ITS. A set of 335 chemical features, including putatively identified flavonoids, phospholipids, peptides, amino acid derivatives, indolic phytoalexins, a glucosinolate and a glucosinolate downstream product was detected. Major taxa in horseradish roots belonged to Cantharellales, Glomerellales, Hypocreales, Pleosporales, Saccharomycetales and Sordariales. Most abundant genera included typical endophytes such as Plectosphaerella, Thanatephorus, Podospora, Monosporascus, Exophiala and Setophoma. A surprising dominance of single taxa was observed for many samples. In summary, 35.23% of reads of the plant endophytic fungal microbiome correlated with changes in the plant metabolome. While the concentration of flavonoid kaempferol glycosides positively correlated with the abundance of many fungal strains, many compounds showed negative correlations with fungi including indolic phytoalexins, a putative glucosinolate but not major glucosinolates and a glutathione isothiocyanate adduct. The latter is likely an in vivo glucosinolate decomposition product important in fungal arrest. Our results show the potency of the untargeted metabolomics approach in deciphering plant - microbe interactions and depicts a complex array of various metabolite classes in shaping the endophytic fungal community.
