Properties of group 2 σ factor triple inactivation strains in varying growth light and high salt conditions.

Growth of the control (CS) and triple inactivation strains at different light conditions is estimated from slow (+) to fast (+++++), and state transitions from no state transitions (−) to normal state transitions (+++). Growth at high salt conditions (§) is compared to growth of the control strain in high salt. The accumulation kinetics (Normal, N; Slow, S; Fast, F) and maximal levels of mRNAs (normal, n; low, l; high, h) are compared to those of the control strain.
