In the version of this article initially published, the Figure 1e,f legend read, “Circulating levels of LH (left panels) and FSH (right panels) in GnRH cells of control (blue) and Dicer mutants (red)”; as the hormones were not measured in GhRH cells, it should have simply read “Circulating levels of LH (left panels) and FSH (right panels) in control (blue) and Dicer mutants (red).” Figure 2b was missing scale bars and has been replaced. The label “TSB-200” was missing from the rightmost bar in Figure 4d. And the treatment in Figure 5c was misidentified as TSB-200 instead of TSB-155. The errors have been corrected in the HTML and PDF versions of the article.
