Review: the dominant flocculation genes of Saccharomyces cerevisiae constitute a new subtelomeric gene family

Yeast. 1995 Sep 15;11(11):1001-13. doi: 10.1002/yea.320111102.


The quality of brewing strains is, in large part, determined by their flocculation properties. By classical genetics, several dominant, semidominant and recessive flocculation genes have been recognized. Recent results of experiments to localize the flocculation genes FLO5 and FLO8, combined with the in silicio analysis of the available sequence data of the yeast genome, have revealed that the flocculation genes belong to a family which comprises at least four genes and three pseudogenes. All members of this gene family are located near the end of chromosomes, just like the SUC, MEL and MAL genes, which are also important for good quality baking or brewing strains. Transcription of the flocculation genes is repressed by several regulatory genes. In addition, a number of genes have been found which cause cell aggregation upon disruption or overexpression in an as yet unknown manner. In total, 33 genes have been reported that are involved in flocculation or cell aggregation.
