Generation of Saccharomyces cerevisiae deletants and basic phenotypic analysis of eight novel genes from the left arm of chromosome XIV

The disruption of eight novel genes was realized in two genetic backgrounds. Among these open reading frames, NO333, NO348 and NO364 presented homologies with other proteins of yeast or other organisms, whereas NO320, NO325, NO339, NO384 and NO388 showed no similarity with any protein. Tetrad analysis of heterozygous deletant strains revealed that NO348, NO364 and NO388 are essential genes for vegetative growth, whereas NO320, NO325, NO333, NO339 and NO384 are non‐essential. Basic phenotypic analyses of the non‐lethal deletant strains as suggested in the six‐pack B0 programme did not reveal any significant differences between parental and mutant strains. © 1998 John Wiley & Sons, Ltd.
