Conservation of the links between gene transcription and chromosomal organization in the highly reduced genome of Buchnera aphidicola

Table 3 Results of the spectral analysis testing the periodicity of Buchnera log₂ nBGT

The periodicity was tested for the original location of genes on the chromosome or according to the different simulated permutations of gene positions. 0: Actual data; 1: conserved operons, order and spacing; 2: conserved operon order; 3: conserved operons; 4: gene scrambling (see text and Figure 6 for details).
**: significant P-value for 99% confidence limits, *: significant P-value for 95% confidence limits
