“…Yeasts are important members in many ecosystems (Fleet 1998) and they form also a major component of the population on leaves (Glushakova and Chernov 2004, Inácio et al 2005, Nakase 2000. Little is known about the ecological role of the phylloplane yeasts.…”

The yeasts were isolated from the leaf surfaces of ten species of trees. The study site was a forest park (Zelezná Studnicka) of the Small Carpathians mountain range. One hundred and thirty seven yeast strains belonging to 13 genera were isolated from 320 samples of leaves and needles. Seventeen yeast species were isolated, but only seven occurred regularly: Aureobasidium pullulans, Cryptococcus laurentii, Pichia anomala, Metschnikowia pulcherrima, Saccharomyces sp., Lachancea thermotolerans, and Rhodotorula glutinis. The remaining species were isolated from the leaves and needles of three or less tree species. A. pullulans, Cr. laurentii, and P. anomala were the most frequently found species and they occurred on leaves and needles of all ten tree species. Saccharomyces sp. occurred in leaf samples collected from eight kinds of trees. M. pulcherrima and L. thermotolerans were found in samples collected from six species of trees. Both these species occurred almost always on the leaves of deciduous trees. Rh. glutinis was the most frequently isolated carotenoids producing species. We have found out that the ascomycetous and basidiomycetous species were present in the leaf samples in approximately equal frequency, contrary to the soil samples taken from this forest park, where the ascomycetous species were found rarely.

“…Another study reported that in terms of species diversity, temporal effects were at times stronger than spatial effect . The stage of growth in which a tree is in has also been shown to have an effect on yeast species diversity . Indeed, yeast in the environment face a diversity of challenges included variations in temperature, moisture, ultraviolet irradiation and nutrient availability, all of which could impact species and strain variation.…”

Yeast are among the most frequent pathogens in humans. The dominant yeast causing human infections belong to the genus Candida and Candida albicans is the most frequently isolated species. However, several non-C. albicans species are becoming increasingly common in patients worldwide. The relationships between yeast in humans and the natural environments remain poorly understood. Furthermore, it is often difficult to identify or exclude the origins of disease-causing yeast from specific environmental reservoirs. In this study, we compared the yeast isolates from tree hollows and from clinics in Hamilton, Ontario, Canada. Our surveys and analyses showed significant differences in yeast species composition, in their temporal dynamics, and in yeast genotypes between isolates from tree hollows and hospitals. Our results are inconsistent with the hypothesis that yeast from trees constitute a significant source of pathogenic yeast in humans in this region. Similarly, the yeast in humans and clinics do not appear to contribute to yeast in tree hollows.

“…Glushakova and Chernov (2007), Pennycook and Newhook (1981) reported that younger leaves show a lower density of yeasts than in mature leaves. Glushakova and Chernov (2004) found that younger leaves provide less exudates causing a lower nutrient source that is available for the growth of a large population of microorganisms. Redford et al (2010) stated that the variables influencing the phylloplane community are leaf age, structure, and composition of smooth cuticles, the chemical composition, and volatile organic molecules released by leaf.…”

Aims: Broussonetia papyrifera (Saeh plant) has many qualities, the inner bark was the material for 'dluwang' papers on which Indonesian historical manuscripts were written, and the leaves have bioactive constituents of medicinal value, and antifungal activities. We investigated the diversity of yeast species associated with leaves from 6 months and 1.5 yearold plants, which is prerequisite to understand the phylloplane yeasts and plant interaction. Methodology and results:The yeasts were isolated from fresh leaves by washing and membrane filtration methods. A total of 16 leaf samples of 6 months and 1.5 year-old plants were collected from four locations in Java, Indonesia, and 2,543 yeast isolates were obtained. Based on similarity of colony morphology, 82 representative yeast isolates were selected and identified based on the sequence analyses of internal transcribed spacer (ITS) regions of rDNA. The identification result showed that they consisted of 17 genera and 32 species. Thirty six of representative yeast isolates belong to 11 genera (18 species) of the phylum Ascomycota and forty six isolates belong to 6 genera (14 species) of the phylum Basidiomycota. Phylogenetic trees showed that the yeast isolates are phylogenetically diverse and distributed in the phyla of Ascomycota (classes Saccharomycetales and Dothideomycetes) and Basidiomycota (classes Microbotryomycetes, Tremellomycetes, and Ustilaginomycetes). Conclusions, significance and impact of study: The phylloplane yeasts of B. papyrifera (Saeh plant) were taxonomically heterogeneous. This is the first report of the isolation and identification of phylloplane yeasts from B. papyrifera. Phylloplane yeasts may possess antagonistic activity to fungal plant pathogens in their natural habitats.
