In the original article, there were six minor mistakes in Table 1 as published.
The gene group for Eyeless (ey) was stated as Paired is homeobox TFs.
The gene group for Gooseberry (gsb) was stated as Paired is homeobox TFs.
The gene group for Homothorax (hth) was stated as Tale is homeobox TFs.
The gene group for Optix was stated as Six/Sine oculis is homeobox TFs.
The gene group for Retinal Homeobox (Rx) was stated as Paired-like is homeobox TFs.
The gene group for Visual system homeobox 1 (Vsx1) was stated as Paired-like is homeobox TFs.
The correct gene groups are as follows:
The correct gene group for Eyeless (ey) is Paired homeobox TFs.
The correct gene group for Gooseberry (gsb) is Paired homeobox TFs.
The correct gene group for Homothorax (hth) is Tale homeobox TFs.
The correct gene group for Optix is Six/Sine oculis homeobox TFs.
The correct gene group for Retinal Homeobox (Rx) is Paired-like homeobox TFs.
The correct gene group for Visual system homeobox 1 (Vsx1) is Paired-like homeobox TFs.
The corrected Table 1 appears below.
