DOIAbstract
Most of the in-depth studies on insect developmental genetic have been carried out in the fruit fly Drosophila melanogaster, an holometabolous insect, so much more still remains to be studied in hemimetabolous insects. Having Rhodnius prolixus sequenced genome available, we search for orthologue genes of zygotic signaling pathways, segmentation, and tracheogenesis in the R.prolixus genome and in three species of Triatoma genus transcriptomes, concluding that there is a high level of gene conservation. We also study the function of two genes required for tracheal system development in D.melanogaster - R.prolixus orthologues: trachealess (Rp-trh) and empty spiracles (Rp-ems). From that we see that Rp-trh is required for early tracheal develop...
