Representative phenotypic classes of rpoE suppressors

Strain genotypea	Growthb
	SDS/EDTA	22°C	37 oC	42 oC	Glucose	Glycerol
rpoE+	++++	++++	++++	++++	++++	++++
rpoE::cam sup9	+	+	+++	+	++	++
rpoE::cam sup1	+	+++	++++	+++	−	−
rpoE::cam sup5	−	+	+++	++	++	++
rpoE::cam sup21	++ (M)	+ (M)	++++ (M)	+	++ (M)	+

^arpoE⁺ refers to NR670. Shown are data derived from a representative suppressor supⁿ for each of the four suppressor classes.

^bGrowth of suppressor strains is reported relative to that of an rpoE⁺ strain, which was arbitrarily given a “++++” value. No growth is reported as “−”. “(M)” refers to a mucoid growth phenotype. SDS/EDTA = LB agar + 0.5% SDS 0.5 mM EDTA; 22°C, 37°C, and 42°C refer to LB agar incubated at the indicated temperatures; glucose refers to glucose M63 minimal agar; glycerol refers to glycerol M63 minimal agar.
