SEQUENCING THE YEAST GENOME - AN INTERNATIONAL ACHIEVEMENT

The yeast genome is currently being sequenced by a Consortium of European laboratories, in collaboration with a wider international network of researchers. It is expected that within the next two years Saccharomyces cerevisiae will become the first eukaryotic organism to have been completely genetically mapped and sequenced. This article traces the sequencing enterprise from its beginnings, outlining the intentions, the organisation, and the achievements so far. The tasks which remain are discussed, emphasising the follow-on research into the evolution of primitive karyotypes, and, more particularly, into the nature of novel genes revealed during sequencing. The functional analysis of novel genes is attracting an ever wider community of yeast scientists, so that research which began with a decision to sequence a simple genome promises to remain a focus for international cooperation.
