Erd1 prevents Pi loss to the environment. The indicated mutant strains were grown to log phase in SC medium containing tracer levels of [32]Pi radioisotope, washed extensively in Pi-free SC medium, and then in the same medium (A and B) or in SC medium (C). At the indicated times of incubation at 30°, aliquots were removed and cell-free supernatants were analyzed by liquid scintillation counting (A and C) or by TLC (B). Charts illustrate the averages (±SD) of three biological replicates.
