Figure 6From: Conservation of the links between gene transcription and chromosomal organization in the highly reduced genome of Buchnera aphidicolaDifferent kinds of simulated permutations of gene positions applied to the Buchnera chromosome. Singletons are drawn in green whereas genes predicted to be in operons are drawn in red. 0: Original location of genes on the chromosome, 1: permutation preserving both rank and the spacing of the pTU to each other but modifying the rank of the genes between the pTU, 2: permutation preserving the rank but not the spacing between the pTU, 3: permutation of both the rank and the location of pTU, 4: gene positions on the chromosome randomly assigned.Back to article page
