Abstract

We demonstrate that the genes encoding trans- acting factors essential for pre-rRNA processing/ribosomal subunit assembly are responsive to various kinds of stresses such as heat shock, nitrogen deprivation and a secretory defect, in coordination with ribosomal protein genes in Saccharomyces cerevisiae. The rap1-17 mutation, which produces the C-terminally truncated protein of a transcriptional factor Rap1p, affects transcriptional repression of the trans-acting factor genes due to a secretory defect as shown previously for both ribosomal protein and rRNA genes.
