From: Oncopeltus-like gene expression patterns in Murgantia histrionica, a new hemipteran model system, suggest ancient regulatory network divergence

Mh-odd, Mh-eve and Mh-prd are expressed segmentally. aMh-odd was first observed in a broad region around the center of the embryo; b Earlier broad Mh-odd expression resolved into five stripes in a later blastoderm-stage embryo, as the germband started to invaginate at the posterior; cMh-odd was observed in stripes anterior to the SAZ in an early germband; d Anterior SAZ striped expression of Mh-odd continued in later germbands, in addition to dots of expression seen in the head lobes; eMh-eve was observed in the posterior two-thirds of an early blastoderm-stage embryo (16–24 h AEL). f A later blastoderm-stage embryo (24–36 h AEL) where Mh-eve is expressed in five stripes. g As invagination (indicated by arrowhead) begins to occur, Mh-eve is expressed in six stripes. h In an early germband, there are four stripes (arrowheads) visible with broader expression closer to the posterior SAZ (bracket). i In a later germband, only four distinct bands are visible and the broader domain of expression to the posterior has disappeared. j A double stain showing Engrailed in brown and Mh-eve in purple. Arrowheads indicate fading stripes exiting the SAZ kMh-prd is expressed in six stripes at germband invagination. Arrow indicates invagination. lnMh-prd expression as germband elongation proceeds. Embryos are shown with the anterior to the left
