Abstract: Nutritional restrictions such as calorie restrictions are known to increase the lifespan of various organisms. Here, we found that a restriction of sulfur extended the chronological lifespan (CLS) of the fission yeast Schizosaccharomyces pombe. The restriction decreased cellular size, RNA content, and ribosomal proteins and increased sporulation rate. These responses depended on Ecl1 family genes, the overexpression of which results in the extension of CLS. We also showed that the Zip1 transcription factor results in the sulfur restriction-dependent expression of the ecl1^+ gene. We demonstrated that a decrease in ribosomal activity results in the extension of CLS. Based on these observations, we propose that sulfur restriction extends CLS through Ecl1 family genes in a ribosomal activity-dependent manner.
