Figure 9. WHI5 toxicity is dependent on HOS3 and RPD3.

Figure 9

(A) cln3Δ (BY4290), cln3Δ rpd3Δ (BY4297), cln3Δ hos3Δ (BY4296), and cln3Δ rpd3Δ hos3Δ (BY4298) strains harboring a methionine-repressible WHI5 construct (pBA1975) or vector control (pBA228v) were spotted in serial 10-fold dilutions on medium lacking methionine. In a similar experiment, pho85Δ (BY391), pho85Δ rpd3Δ (BY4300), pho85Δ hos3Δ (BY4299), and pho85Δ rpd3Δ hos3Δ (BY4301) strains bearing a galactose-inducible WHI5 plasmid (pBA1973) or appropriate vector control (pEG-H) were spotted in serial 10-fold dilutions on galactose-containing medium. Plates were incubated at 30°C for 48 h. (B) Deletion of HOS3 partially restores growth of a cln3Δ pho85Δ strain. The indicated strains (BY263; BY4291, BY4292, BY4455–4461) were spotted in serial 10-fold dilutions on rich medium (YPED) and incubated at 30°C for 48 h. (C) Deletion of RPD3 and HOS3 partially restore viability of a cln3Δ bck2Δ strain. The indicated strains (BY4741; BY2948, BY4462–4468) were spotted in serial 10-fold dilutions on glucose-containing medium (YPED) to repress CLN3 expression. Strains were also spotted on medium containing galactose as a control. Plates were incubated at 30°C for 72 h.
