Spt phenotype of asf1Δ and bdf1Δ strains. (A) Schematic drawing of the assay for Spt phenotype. Mutations in the SPT gene (spt−) suppresses transcriptional defect of the HIS4 gene in the SPT+ strain caused by insertion of the Ty element. The Spt phenotype is measured on the medium lacking histidine. (B) Spt phenotype of ASF1 disruptant (asf1Δ). The growth of cells carrying the asf1Δ allele on control plates (+His) and plates lacking histidine (−His) were measured. spt6 mutant strain serves as a positive control. (C) The Spt phenotype of BDF1 disruptant (bdf1Δ); the asf1Δ strain served as a positive control. The number of cells in each spot is indicated at the bottom.
