The authors regret that errors appeared in the original html and pdf versions of the paper. The heading to Figure 6 should read “Fra1 inhibits Blimp1 expression.” In the acknowledgements, grants Mi932/2 and TRR130 were mistakenly linked to G. Schett. These grants support D. Mielenz. All versions of the article are now correct.
