Figure 6. Correlation between resistance towards proteotoxic stress and proteasome abundance.

Figure 6

Increased resistance to canavanine, ER or oxidative stress upon UBR2 or MUB1 deletion. Serially diluted log phase cultures of WT, rpn4Δ, ubr2Δ, mub1Δ, rpn4Δ ubr2Δ and rpn4Δ mub1Δ strains were spotted on (A) synthetic media in the presence (left panel) or absence (middle panel) of arginine, in the absence (left and middle panel) or presence (right panel) of 3 µg/ml of the arginine analog canavanine, on (B) complete media in the absence (left panel) or presence of 0.5 µg/ml tunicamycin (right panel) or on (C) complete media in the absence (left panel) or presence of 50 µM cadmium chloride (right panel).
