Previous studies in the yeast Saccharomyces cerevisiae have shown that genes encoding subunits of macromolecular complexes have similar evolutionary rates (K) and expression levels (E). Besides, it is known that the expression of a gene is a strong predictor of its rate of evolution (i.e., E and K are correlated). Here we show that intracomplex variation of subunit expression correlates with in...

An improved pulsed-field electrophoresis program was developed to study differently sized chromosomes within the genus Saccharomyces. The number of chromosomes in the type strains was shown to be nine in Saccharomyces castellii and Saccharomyces dairenensis, 12 in Saccharomyces servazzii and Saccharomyces unisporus, 16 in Saccharomyces exiguus and seven in Saccharomyces kluyveri. The sizes of i...

Alcoholic fermentation is a polimicrobial process involving a large number of genera and species of yeast and bacteria. Th e major yeast genera involved in this process belongs to the Saccharomyces spp. Th e aim of this study was the isolation, identifi cation and determination of genetic diversity of indigenous Saccharomyces cerevisiae natural population taken from cv. Plavac mali from seclude...

Yeast Saccharomyces cerevisiae is one of the simplest eukaryotic model organisms to study various parameters ethanol tolerance and has attracted a huge consideration for cost-conscious production bioethanol by fermentation soluble sugars. Ethanol crucial efficient from S. cerevisiae. In this study, we examined role HAL5 protein kinase in comparing cell growth, survival, stress responses wild-ty...
