Background: Yeasts are cosmopolitan in nature. They have been found in soil with widely different texture, chemical composition, humidity, and hydrogen ion concentration at numerous geographic locations, atmospheric condition, whether in uncultivated or cultivated soils. Materials and Methods: The dilution plate method for 75 soil samples was collected from 21 area in Basrah and Dhi Qar Provinces, Southern Iraq. Soil samples were collected from both cultivated and uncultivated lands to seek the presence of ascomycetous yeasts. Results: The results reported a 1st time record of six species belong to five genera; moreover, test the ability of yeasts on halotolerance and osmotolerance media the finding showed they have variation in tolerance of salt and sugar beside of reported he ability of them in growth at 15°C, 25°C, and 37°C, the results showed different in ability of growth at three temperatures. For in addition for more accurate discrimination between morphological alike species, a molecular study represented by polymerase chain reaction and DNA sequencing of internal transcribed spacer (ITS1-ITS2) region rDNA gene was conducted confirm our findings. Conclusions: This first study in Iraq for molecular identification of ascomycetous yeast revealed about biodiversity of yeast in soil. [ABSTRACT FROM AUTHOR]
