...Katie Reding; Mengyao Chen; Yong Lu; Alys M. Cheatle Jarvela; Leslie Pick ABSTRACT The discovery of pair-rule genes (PRGs) in Drosophila revealed the existence of an underlying two-segment-wide prepattern directing embryogenesis. The milkweed bug Oncopeltus fasciatus , a hemimetabolous insect...

... that giant might not act as a gap gene in short and intermediate germ insects. Oncopeltus fasciatus is an intermediate germ insect that is an outgroup to the clade containing Drosophila and Tribolium . We cloned the Oncopeltus homolog of giant and determined its expression and function during segmentation...

... determination of leg identity is thought to result from regulatory interactions between the Hox genes and the antennal-specifying gene homothorax. Based on RNA-interference, a functional analysis of the selector gene tiptop and the Hox gene Antennapedia in Oncopeltus fasciatus embryogenesis is presented...

... cell behaviour segment border cell division insect epidermis pattern regulation Oncopeltus fasciatus The confrontation of cells from the anterior region of an abdominal segment of the milkweed bug, Oncopeltus fasciatus , with those from the posterior region results in the generation...
