Figure 2. Effect of the PSTE18-URA3 gene on growth of haploids and diploids.

Figure 2

(A) The haploid and diploid PSTE18-URA3 strains display opposite growth phenotypes on plates lacking uracil or containing 5-FOA. The strains were grown for 2–3 days at 30°C. (B) The growth phenotype of the diploid PSTE18-URA3 strain can revert to that of haploid after sporulation. The indicated diploid strains were sporulated, tetrads were dissected and spore progeny was grown on YPD plate for 3 days at 30°C. Then, the cells were replicated on the indicated plates and grown for 2–3 days at 30°C.
