Annotation of the conserved domains of the foraging gene. A) Annotation of the cGMP-dependent protein kinase foraging showing conserved domains. CAP-ED: effector domain of the CAP family of transcription factors, STKc_cGK_PKG: catalytic domain of the cGMP-dependent protein kinase. B) Partial sequence alignment of catalytic domain in hymenoptera showing the single amino acid replacement in the A-loop region (asparagine/histidine). The red line indicates the two A-loop regions and the red box encloses the amino acid replacement. C) Partial sequence alignment of A-loop region in catalytic domain in known Formicidae. The red box encloses the asparagine/histidine replacement site in eight ant species. The asparagine mutation is present in 6 out of 8 species.
