Seasonal dynamics of the structure of epiphytic yeast communities

  title={Seasonal dynamics of the structure of epiphytic yeast communities},
  author={Anna M. Glushakova and I. Yu. Chernov},
The seasonal dynamics of the species structure of epiphytic yeasts on the leaves and in the flowers of 25 plant species was studied throughout the period of their vegetation. It was shown that, on average for the vegetation period, the composition of epiphytic yeast communities was nonspecific. The same species of epiphytic yeasts dominated on different plant species, irrespective of their taxonomic identity and ecological peculiarities. However, different species of yeasts exhibited different… 

Specific features of the dynamics of epiphytic and soil yeast communities in the thickets of Indian balsam on mucky gley soil

The strong difference between the yeast communities in the phyllosphere of Indian balsam and in the soil under its thickets is apparently related to the fact that the annual hygrophytes are decomposed very quickly and an intermediate layer between thephyllosphere and the soil (the litter layer), in which epiphytic microorganisms can develop, is not formed.

Yeasts in the flowers of entomophilic plants of the Moscow region

The number of yeasts in the flowers was shown to increase gradually during the vegetation period, and reached the maximum during summer-autumn, while the total abundance and ratio of the yeast species in the Flowers depended entirely on the blooming time, rather than on the taxonomic position of the plants.

Yeast Communities of Vineyards in Dagestan: Ecological, Taxonomic, and Genetic Characteristics

The DNA fingerprinting method used for Saccharomyces cerevisiae strains isolated from the vineyards of Dagestan showed their high genetic heterogeneity.

Yeast Diversity Associated with the Phylloplane of Corn Plants Cultivated in Thailand

This work indicated that a majority of yeast associated with the phylloplane of corn plant belongs to the phylum Basidiomycota, which is less well understood in tropical regions than in temperate ones.

The influence of Aster x salignus Willd. Invasion on the diversity of soil yeast communities

The invasion of Aster x salignus has a clear effect on soil yeast complexes reducing their taxonomic and ecological diversity.

Yeast communities in Sphagnum phyllosphere along the temperature-moisture ecocline in the boreal forest-swamp ecosystem and description of Candida sphagnicola sp. nov.

This study confirmed the low occurrence of tremellaceous yeasts in the Sphagnum phyllosphere and isolated and identified by molecular methods a total of 15 species of yeasts, some of which were differentiated from hitherto known species in physiological tests and phylogenetic analyses.

The Influence of Heating Mains on Yeast Communities in Urban Soils

It is demonstrated that the number and species structure of soil yeast communities in urban soils change significantly under the influence of the temperature factor and acquire a mosaic distribution pattern.

Yeast communities of Formica aquilonia colonies

Yeast abundance and species diversity in the colonies of Formica aquilonia ants in birch–pine grass forest near Novosibirsk, Russia, were studied and highly specific yeast communities formed in the colony differ from the communities of surrounding soil.

Distribution of yeast complexes in the profiles of different soil types

The results showed that yeasts could be used for soil bioindication on the basis of specific yeast complexes in the profiles of different soil types rather than individual indicative species.

Different plant compartments, different yeasts: The example of the bromeliad phyllosphere

Bromeliads proved to be a good ecological model for prospecting new yeasts and for studies on the interaction between plants and yeasts, andVariables such as bromeliad subfamilies and functional types, as well as plant compartments, were statistically significant, though inconclusive and with low explanatory power.



Seasonal dynamic of the numbers of epiphytic yeasts

The numbers of epiphytic yeasts on the leaves and flowers of 25 plant species throughout their vegetation period was determined and three types of dynamics were revealed: year-round with an increase in autumn-winter, year- round without visible changes, and seasonal with a terminal increase for annual plants.

Community Structure of Yeast Fungi in Forest Biogeocenoses

The yeast diversity in forest biogeocenoses is shown to surpass that in other geographic zones and manifests itself in a greater number of species occurring in similar arrays of substrates, and in a higher differentiation of the yeast population with respect to its habitat type.

Estimation and Diversity of Phylloplane Mycobiota on Selected Plants in a Mediterranean–Type Ecosystem in Portugal

Interestingly, a few species seemed to be associated with a particular plant, notably in the case of the evergreen shrub C. albidus, suggesting that such species might be genuine phylloplane inhabitants (or at least of aerial plant surfaces) even though they appeared not to display host specificity.

Some physiological characters of yeasts from soils and allied habitats.

Almost all the species tested could use cellobiose, and the majority could synthesize growth factors and use a range of organic acids as carbon sources, including all the pigmented ones examined.

Biogeography of the yeasts of ephemeral flowers and their insects.

We studied specific yeast communities vectored by beetles, drosophilids, and bees that visit ephemeral flowers, mostly in the genus Hibiscus and in the families Convolvulaceae and Cactaceae, in the

Potential of yeasts as biocontrol agents of soil-borne fungal plant pathogens and as plant growth promoters

The potential of soil yeasts to suppress a wider range of soil-borne fungal plant pathogens and to promote plant growth is explored in a review of soil microorganisms used to control postharvest diseases.

Seasonal changes in the apple phylloplane microflora

Microbial populations in the phylloplane of unsprayed ‘Dougherty’ apple trees were estlfllated by maceration-dilution platmg and spore fall methods during two growing seasons in Auckland, New Zealand, finding that newly unfurled shoot leaves did not have a distinctive microflora derived from the vegetative buds; they supported a sparse microFlora which included air spora-derived species.

Assimilation tests using, as sole carbon and energy sources, low molecular weight aromatic compounds appear to be potentially useful in taxonomic studies of basidiomycetous yeasts.
