Evaluation of PFGE and mtDNA restriction analysis methods to detect genetic diversity of saccharomyces cerevisiae strains associated to <em>Vitis vinifera</em>
Aims: The aim of this work was realize a comparative study of two different methods of Saccharomycec cerevisiae yeast strain characterization. Methods and results: Pulsed-field gel electrophoresis analysis (PFGE) and mitochondrial DNA (mtDNA) restriction analysis have been carried out to differentia...
