There was an error published in Development138, 995-1004.
On p. 1000, it was incorrectly stated that Islet can repress Vsx in A13.474 but not in A11.117. The reverse is true, as stated in the legend to Fig. 6B. The corrected text appears below.
Vsx can actually induce ectopic Islet expression (Fig. 6C), while Islet can repress Vsx in A11.117, but not in A13.474 (Fig. 6B), hinting at a more complicated interaction between these two genes.
The authors apologise to readers for this mistake.
