Abstract

With the aim of developing new tools for the characterisation of wine yeasts, by means of databases available on-line we scanned the genome of Saccharomyces cerevisiae in search of potentially polymorphic targets. As we have previously observed for SED1, we found that other genes coding for cell wall proteins contain minisatellite-like sequences. A polymerase chain reaction (PCR) survey of SED1 and three of these others, namely AGA1, DAN4 and HSP150, in a population of wild S. cerevisiae demonstrated that these genes are highly polymorphic in length and represent a sink of unexplored genetic variability. The primer pairs designed on the gene open reading frames yield stable and repeatable amplification profiles that show a level of resolution that allows the clear discriminate between different strains. These can therefore be utilised for PCR-based typing of S. cerevisiae.
