Trascription of sig genes during normal growth. Measurement of relative concentrations of sigB, sigC, sigD and sigE mRNAs in Synechocystis by quantitative RT-PCR during three stages of normal growth: mid log phase in black (A750 = 1); early stationary phase in white (A750 = 8); and late stationary phase in grey (A750 = 12.6). Each sample was measured in triplicate and the standard deviation is indicated by error bars. Values were normalized to the rpoA transcript.
