The Ere1 and Ere2 proteins function in the retromer recycling pathway. Serial dilutions (fourfold) of wild-type and different mutant cells (as indicated) were grown on synthetic media plates with or without 2.0 μg/ml canavanine for 2 d at 26°C. The canavanine-resistant phenotype of each strain was scored based on the relative growth of serial dilutions on canavanine plates. Relative growth: no growth at 0.1 OD600/ml was scored as −; growth at 0.1 OD600/ml was scored as +; growth at 2.5 × 10−2 OD600/ml was scored as ++; growth at 1.56 × 10−3 OD600/ml was scored as ++++.
