YEAST GENOME ANALYSIS: FROM SEQUENCE TO FUNCTION

The budding yeast, Saccharomyces cerevisia, is one of the most important and accessible model eukaryotes employed in molecular biological research. Yeast has a small genome, less than four times the size of that of E. coli, and divides it between a large number of chromosomes (sixteen, in all). The European Community Yeast Genome Sequencing Consortium is actively engaged in the sequencing of these chromosomes. We have completed the sequence of chromosomes III and XI and will soon finish that of chromosome 11. This presentation will review current progress in yeast genome sequencing and discuss the general rules which are emerging concerning genome organization, recombination and evolution.

Systematic genome sequencing is discovering new genes at a far faster rate than has previously been the case for either classical or molecular genetics. For approximately half of the genes studied, the sequence gives no clue as to function. It is evident that the functional analysis of these novel genes will require a methodology every bit as systematic and efficient as DNA sequencing itself. The prospects for such a function search will be discussed, emphasising the need to establish a hirearchical taxonomy of gene function.
