Colorimetric RNA in situ hybridization of the studied transcription factors in the worms in the asexual phase. For each panel, the name of the hybridized gene is indicated in the box above. Sensory pits are marked with a dotted circle. The expression was detected in the following morphological structures: pharynx (red arrowheads), brain (double white arrowheads), longitudinal nerve cords (white arrows), gut tissue (blue arrowheads), distinct pharyngeal domains (double red arrowheads), around the mouth opening (green arrowhead), single cells spread throughout worm body (magenta arrowheads) and in the sensory pits (black arrowheads). Worms are mounted dorsoventrally in all panels with the exception of the laterally mounted animal in panel U. Scale bars 20 μm
