...Nipam H. Patel; David C. Hayward; Sabbi Lall; Nicole R. Pirkl; Daniel DiPietro; Eldon E. Ball While the expression patterns of segment polarity genes such as engrailed have been shown to be similar in Drosophila melanogaster and Schistocerca americana (grasshopper), the expression patterns of pair...

... and gooseberry-neuro in short germ flour beetles and grasshoppers. During Drosophila embryogenesis, paired acts as one of several pair-rule genes that define the boundaries of future parasegments and segments, via the regulation of segment polarity genes such as gooseberry, which in turn regulates gooseberry...

...Claudia Seidel; Gerd Bicker ABSTRACT The grasshopper embryo has been used as a convenient system with which to investigate mechanisms of axonal navigation and pathway formation at the level of individual nerve cells. Here, we focus on the developing antenna of the grasshopper embryo ( Schistocerca...

... roles of FGFs have made experimental tests of these signals difficult in vivo. In the Drosophila FGF receptor mutant heartless , glia migrate to axons, but fail to elongate around them. This study shows that in the similar but larger grasshopper CNS, FGF signalling is likely to mediate one step...

... in the establishment of appropriate axon trajectories, we have characterized a novel secreted semaphorin in grasshopper, gSema 2a. Sema 2a is expressed in a gradient in the developing limb bud epithelium during Ti pioneer axon outgrowth. We demonstrate that Sema 2a acts as chemorepulsive guidance molecule critical...

... is expressed by bands of epithelial cells in the developing grasshopper limb bud, functions as an attractive/permissive cue for the growth cones of the subgenual organ. In addition, we demonstrate that Semaphorin I is needed for initial axonal outgrowth from the subgenual organ. These results are consistent...

...María D. Ganfornina; Diego Sánchez; Michael J. Bastiani ABSTRACT Lazarillo, a protein recognized by the monoclonal antibody 10E6, is expressed by a subset of neurons in the developing nervous system of the grasshopper. It is a glycoprotein of 45×10 3 M r with internal disulfide bonds and linked...

...Rachel Dawes; Iain Dawson; Francesco Falciani; Guy Tear; Michael Akam ABSTRACT We describe an unusual Antennapedia class homeobox gene from the grasshopper Schistocerca gregaria (Orthoptera, African Plague Locust). Its sequence is not sufficiently similar to that of any other insect Hom-Hox gene...
