In Fig. 2d of this Letter, two different representative stage 11 embryos were mistakenly shown for the green (scyl) and red (chrb) channels. The merge image showed the signal of both genes in the ‘scyl’ embryo. This has now been corrected in Fig. 1 of this Corrigendum, which shows the expression of both genes in the same embryo. Both genes are highly co-expressed, even more so than previously reported.
