Abstract: Yeast Saccharomyces cerevisiae is a good eukaryotic model for studying the molecular
mechanism of toxic metal ion stress. Numerous studies have been performed on the signal transduction
induced by toxic metal ion stress. The physiological process of eukaryotic cells has been
studied, and various stress factors have been elucidated by constructing a gene deletion library. The
sensitivity and tolerance mechanism of yeast under metal ion stress has been widely studied. The
sensitive genes induced by metal ion stress will provide a key foundation for studying the gene
function of eukaryotic organisms. In addition, the functions of genes in response to metal ion stress
mainly participate in regulating ion homeostasis, high glycerin pathway, vacuole protein separation
pathway, cell wall integrity pathway, and cell autophagy. However, the interaction of these signal
pathways and the detailed response mechanism need to be further studied. In addition, the technique
of genomics and proteomics will help study the detailed molecular mechanism induced by
toxic metal ion stress. Thus, the sensitive genes related to various signal pathways under toxic metal
ion stress will be reviewed in the yeast S. cerevisiae.
