Two novel genes involved in the sexual development of Schizosaccharomyces pombe. 1995

We isolated two sterile mutants of Schizosaccharomyces pombe. One of them was mapped close to ste13 (8 cM). Since it turned out to be allelic with the hitherto unmapped ral2, its linkage with ste13 localizes ral2 on the right arm of chromosome II. The other mutant defines a novel class-I ste gene, ste15, closely linked to ste7 (4 cM) on chromosome I. ste15 is conjugation-specific and acts upstream of pat1 and ras1. During its genetic analysis, a phenotypic suppression of ste12-N9 was observed which was caused by mutations in the unlinked gene ssw1.

UI	MeSH Term	Description	Entries
D004843	Epistasis, Genetic	A form of gene interaction whereby the expression of one gene interferes with or masks the expression of a different gene or genes. Genes whose expression interferes with or masks the effects of other genes are said to be epistatic to the effected genes. Genes whose expression is affected (blocked or masked) are hypostatic to the interfering genes.

D016153	Genes, Suppressor	Genes that have a suppressor allele or suppressor mutation (SUPPRESSION, GENETIC) which cancels the effect of a previous mutation, enabling the wild-type phenotype to be maintained or partially restored. For example, amber suppressors cancel the effect of an AMBER NONSENSE MUTATION.
