Abstract
- Molecular genetic analysis of melibiose-fermenting Saccharomyces strains isolated from fermentative processes and natural sources in different world regions was conducted to deduce the evolutionary diversity of Saccharomyces yeasts and find new α-galactosidase MEL genes. The species S. bayanus, S. mikatae, and S. paradoxus were shown to have a single copy of MEL and not accumulate polymeric genes, unlike some S. cerevisiae populations. The polymeric genes MELp1 and MELp2 were identified in S. paradoxus for the first time. Genes identical by 98.7% are located on the chromosomes X and VI, respectively. Phylogenetic analysis indicates that MEL genes of the Saccharomyces yeasts are species-specific. [ABSTRACT FROM AUTHOR]
