Results of real-time RT-PCR analysis of late competence genes. The expression levels of late competence genes are presented relative to that of the wild type (UA159), which was arbitrarily assigned a value of 1. (A) Expression level of comEA in the irvR mutant strain GN01R compared to the levels in the wild-type strain UA159 (P < 0.001) and the irvR irvA double-mutant strain GN01RA (P < 0.01). (B) Expression level of comYA in strain GN01R compared to the levels in the wild type (P < 0.0001) and GN01RA (P < 0.0001). (C) Expression level of dprA in strain GN01R compared to the levels in the wild type (P < 0.0001) and GN01RA (P < 0.01) All data are presented as the averages of the results of five independent experiments. Statistical analysis was performed by using the two-tailed Student's t test. Error bars show standard deviations.
