Sixty-five families of genes most frequently controlled by attenuation. For each gene family described on the left, the histogram bar shows the fraction of candidates already described in the Rfam database or in the literature. The green curve corresponds to the cumulated portion of families with at least one described candidate, from the first family to the 65th. The red curve indicates the absolute number of candidates in each family.
