“…An estimate suggested that only up to 5% of the yeast species belong to the Basidiomycota in nature. At the time of writing (October 2022), about 500 species of basidiomycetous yeasts have been widely recognized; among them, the psychrophilic yeast belonging to the genus Vishniacozyma and Rhodotorula have been discovered in northern regions, glacial mountains, and polar habitats [ 2–4 ]. The fungi that adapted to grow in the cold environment can decompose diverse types of organic compounds that play an essential role in the nutrient cycles of polar microbial ecosystems [ 5–8 ].…”

Two strains, YP344 and YP579 were isolated from soil samples in Pocheon City, Gyeonggi Province, South Korea. The strains YP344 and YP579 belong to the genus Vishniacozyma and Dioszegia , respectively. The molecular phylogenetic analysis showed that the strain YP344 was closely related to Vishniacozyma peneaus. Strain YP344 T differed by four nucleotide substitutions with no gap (0.70%) in the D1/D2 domain of the LSU rRNA gene and 16 nucleotide substitutions with 8 gaps (5.76%) in the ITS region. On the other hand, the strain YP579 T varied from the type strain of the most closely related species, Dioszegia zsoltii var. zsoltii , by 6 nucleotide substitutions with four gaps (1.64%) in the D1/D2 domain of LSU rRNA gene and 26 nucleotide substitutions with 14 gaps (8.16%) in the ITS region. Therefore, the name Vishniacozyma terrae sp. nov. and Dioszegia terrae sp. nov. are proposed, with type strains YP344 T (KCTC27988 T ) and YP579 T (KCTC 27998 T ), respectively.

“…Although nearly 500 basidiomycetous yeasts have been widely documented, only a few psychrophilic Vishniacozyma and Rhodotorula yeasts have been discovered in northern regions, glacial mountains, and polar habitats [ 9 , 10 ]. Among cold-adapted endophytic fungi, Vishniacozyma , Cryptococcus, Rhodotorula , and Aureobasidium yeasts formed a complex assemblage with biocontrol antagonists, such as Cladosporium uredinicola and Coprinellus micaceus , endophytic generalists (e.g., Alternaria and Penicillium ), and plant pathogens (e.g., Cercospora and Myrothecium ) discovered in whet spikes and medicinal plants [ 11 , 12 ]. Based on GC–MS spectra analysis, Vishniacozyma victoriae within Tremellales produces a diverse range of bioactive metabolites [ 12 ] and was a subject of the diversity bioprospecting of antimicrobial metabolites [ 13 ] and enzymes [ 14 ].…”

It has been suggested that the phyllosphere-associated pigmented yeasts of genera Vishniacozyma , Rhodotorula , and Sporoblomyces are helping plant growth and ecological adaptation to cold environments [ 15 ] by synthesizing substantial amounts of auxin and zeatin [ 16 , 17 , 18 ].…”

Tremellomycetes Yeasts in Kernel Ecological Niche: Early Indicators of Enhanced Competitiveness of Endophytic and Mycoparasitic Symbionts against Wheat Pathobiota

Tremellomycetes rDNA sequences previously detected in wheat kernels by MiSeq were not reliably assigned to a genus or clade. From comparisons of ribosomal internal transcribed spacer region (ITS) and subsequent phylogenetic analyses, the following three basidiomycetous yeasts were resolved and identified: Vishniacozymavictoriae, V. tephrensis, and an undescribed Vishniacozyma rDNA variant. The Vishniacozyma variant’s clade is evolutionarily close to, but phylogenetically distinct from, the V. carnescens clade. These three yeasts were discovered in wheat kernel samples from the Canadian prairies. Variations in relative Vishniacozyma species abundances coincided with altered wheat kernel weight, as well as host resistance to chemibiotrophic Tilletia (Common bunt—CB) and necrotrophic Fusarium (Fusarium head blight—FHB) pathogens. Wheat kernel weight was influenced by the coexistence of Vishniacozyma with endophytic plant growth-promoting and mycoparasitic biocontrol fungi that were acquired by plants. Kernels were coated with beneficial Penicillium endophyte and Sphaerodes mycoparasite, each of which had different influences on the wild yeast population. Its integral role in the kernel microbiome renders Vishniacozyma a measurable indicator of the microbiome–plant interaction. The ability of NGS technology to detect specific endophytic DNA variants and early changes in dynamics among symbionts within the kernel ecological niche enables the prediction of crop disease emergence, suggesting that advanced microbiological testing may be a potentially useful tool for both phytoprotection and more efficient wheat breeding programs.

Since a significant proportion of plant matter is consumed by herbivores, a necessary adaptation for many phyllosphere microbes could be to survive through the guts of herbivores. While many studies explore the gut microbiome of herbivores by surveying the microbiome in their frass, few studies compare the phyllosphere microbiome to the gut microbiome of herbivores. High‐throughput metabarcode sequencing was used to track the fungal community from milkweed (Asclepias spp.) leaves to monarch caterpillar frass. The most commonly identified fungal taxa that dominated the caterpillar frass after the consumption of leaves were yeasts, mostly belonging to the Basidiomycota phylum. While most fungal communities underwent significant bottlenecks and some yeast taxa increased in relative abundance, a consistent directional change in community structure was not identified from leaf to caterpillar frass. These results suggest that some phyllosphere fungi, especially diverse yeasts, can survive herbivory, but whether herbivory is a key stage of their life cycle remains uncertain. For exploring phyllosphere fungi and the potential coprophilous lifestyles of endophytic and epiphytic fungi, methods that target yeast and Basidiomycota fungi are recommended.
