Diversity and Application of Yeasts in the Rhizosphere.

บทคัดย่อ ( Abstract )

The rhizosphere is a thin region of soil around plant roots where microbes, plant roots, and soil constituents interact and is supposed to be the microbial habitat. This region is rich in nutrients and chemical substances secreted from plant roots, which are substantially higher than those found in soil away from plants and serve as a major source of substrates for a variety of microorganisms. Yeasts are a group of unicellular eukaryotic microorganisms that inhabit the rhizosphere. Rhizosphere yeasts are rich in species diversity and population levels. The diversity of yeast in the rhizosphere varies depending on the season, soil type and depth, plant species, and location. Yeast species belonging to the genus Cryptococcus, Candida, Torulaspora, and Meyerozyma are the most frequently isolated from the rhizosphere. Presently, metagenomics, an effective method for phylogenetic identification and functional characterization of uncultured microorganisms, is currently being used to investigate the community and diversity of yeast and other microorganisms in the rhizosphere. The role of rhizosphere yeast in terms of plant growth promotion is well investigated and reported, such as organic matter mineralization, phosphate solubilization, nitrogen compound and inorganic sulfate transformation, plant root growth promotion, against root pathogens, and even acting as a food source for other organisms. However, information and examination of yeast ecology and interaction among yeasts, plants, and other microorganisms is limited. In this chapter, the diverse culturable and unculturable yeast species that inhabit the rhizosphere are reviewed. Furthermore, the interactions between yeast and plants are discussed with a focus on their mechanisms for promoting plant growth.
