Here we review cell cycle control in the fission yeast, Schizosaccharomyces pombe, in response to an abrupt reduction of glucose concentration in culture media. S. pombe arrests cell cycle progression when transferred from media containing 2.0% glucose to media containing 0.1%. After a delay, S. pombe resumes cell division at a surprisingly fast rate, comparable to that observed in 2% glucose. We found that a number of genes, including zinc-finger transcription factor Scr1, CaMKK-like protein kinase Ssp1, and glucose transporter Ght5, enable rapid cell division in low glucose. In this article, we examine whether cell cycle checkpoint-like control operates during the delay and after resumption of cell division in limited-glucose. Using microarray analysis and genetic screening, we identified several candidate genes that may be involved in controlling this low-glucose adaptation.
