Abstract

Aim. Development of approaches for isolating yeast symbionts from the rhizosphere of various varieties of winter wheat for their further taxonomic identification, as well as studying the influence of yeast species on the growth and development of wheat plants. Methods. Isolation and identification of yeast from the root microbiome of selected wheat varieties was carried out using microbiological and microscopic research methods. Results. As a result of the investigation, conditions were selected, isolation and primary identification of yeast from the root microbiome of winter wheat varieties in different growing periods was carried out. The following yeast species were identified: Saccharomyces serevisiae, Hanseniaspora uvarum, Papiliotrema terrestris, Pichia fementans, Candida subhashii, Torulaspora delbruecki and Candida sp. Conclusions. The difference in the species composition of yeast-symbionts in different periods of development of winter wheat varieties Lisova Pisnya, Pereyaslivka, Bohdana, Smuglyanka, Podolyanka, Kolonia, Reform and Rebel was noted. The obtained data emphasize the importance of studying the rhizosphere microbiome, in particular the functional role of yeast, for understanding the mechanisms of interaction between the plant and the soil, as well as for the development of effective agronomic strategies in the cultivation of wheat and other crops.
