Because the toxicity of canavanine depends on its cellular uptake mediated by plasma membrane arginine transporters, the isolation of canavanine-resistant mutants in model microorganisms yielded pioneering discoveries on arginine transporter genes (Schwartz et al. 1959; Grenson et al. 1966). In the budding yeast Saccharomyces cerevisiae, all canavanine-resistant mutants isolated are loss-of-function mutants of the arginine transporter gene CAN1 (Whelan et al. 1979; Hoffmann 1985). Canavanine-based counter selection of CAN1 has been widely used as an assay for studying mutagenesis and genome instability in S. cerevisiae (Drake 1991; Tishkoff et al. 1997; Hackett et al. 2001; Lang and Murray 2008; Kim et al. 2011; Jiang et al. 2021).
