Burst sizes of phages with various cosN and A alleles normalized to λ cosN⁺ A^+a

Genotype	Burst size (PFU/cell) in:
Genotype	MF1427	MF1972
cosN⁺ A⁺	1.0	0.29
cosN G₂C C₁₁G A⁺	0.01^b	8.2 × 10⁻⁴
cosN G₂C C₁₁G A-E₅₁₅G	0.83	0.18
cosN G₂C C₁₁G A-N₅₀₉K	0.69	0.03
cosN G₂C C₁₁G A-R₅₀₄C	0.43	0.07
cosN⁺ A-E₅₁₅G	1.01	0.23
cosN⁺ A-N₅₀₉K	0.60	0.29
cosN⁺ A-R₅₀₄C	0.38	0.25

λ-P1:5R Kn^r cI857 lysogens in MF1427 (IHF⁺) and MF1972 (IHF⁻) were induced and plated on MF1427. Values are PFU/induced cell, normalized to λ cosN⁺ A⁺ induced from MF1427, and are the averages of three experiments. The average burst of λ cosN⁺ A⁺ on MF1427 was 243 and that on MF1972 was 71.6.

These lysates were plated on MF2548 to reduce the background of revertants which arise spontaneously on MF1427.
