  • a The log red/green ratios from replicate arrays were averaged at each time point. For each OD600, the average log2 value for each AC1481 sample was subtracted from the corresponding log2 AC1500 value. The results are expressed as the fold difference in expression between the two strains. Data from all of the arrays used in this study are available elsewhere (6).

  • b Designations of the open reading frames in the TIGR4 sequence which are on the microarray.
