FIG. 3.

Correlation between the YOR1 gene and the aur3^R mutation in AbA resistance. yor1-disrupted haploid A141-9A cells were crossed with aur3^R mutant AL33-18C, and the diploids obtained were allowed to sporulate. Tetrad segregants from the diploids were streaked onto YPD agar plates, the plates were incubated at 30°C for 2 days, and the segregants were replicated on a YPD agar plate with 1.5 μg of AbA per ml (B) or an SD plate without uracil (−URA) (A).
