Deletions of the iso-1-cytochrome c and adjacent genes of yeast: discovery of the OSM1 gene controlling osmotic sensitivity.
Some of the deletions in the yeast Saccharomyces cerevisiae that encompass the CYC1 gene, which determines iso-1-cytochrome c, extend into the OSM1 gene, causing inhibition of growth on hypertonic media, and into the RAD7 gene, causing sensitivity to UV light. Two deletions (cyc1--363 and cyc1--367) encompass only the CYC1 gene, two deletions (cyc1--366 and cyc1--368) encompass the CYC1 and OSM1 genes, three deletions (cyc1--1, cyc1--364 and cyc1--365) encompass the CYC1, OSM1 and RAD7 genes, while none of the deletions extend into the closely linked SUP4 gene.
