...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...

...-neuro, a gene expressed later in the developing nervous system. Using a crossreactive antibody, we show that the embryonic expression of Pax group III genes in both the flour beetle Tribolium and the grasshopper Schistocerca is remarkably similar to the pattern in Drosophila . We also show that two Pax...

...Julie Broadus; Chris Q. Doe ABSTRACT In the Drosophila CNS, early neuroblast formation and fate are controlled by the pair-rule class of segmentation genes. The distantly related Schistocerca (grasshopper) embryo has a similar arrangement of neuroblasts, despite lack of known pair-rule gene...

... that segments can be generated sequentially at the molecular level, and suggested that pair-rule pre-patterning might not be shared by all insects. At first, the results from Schistocerca and Tribolium might seem contradictory: both have embryos of the short germ type, but only Tribolium seems to use...

...Thomas Meier; Fabienne Chabaud; Heinrich Reichert ABSTRACT To determine the generality of developmental mechanisms involved in the construction of the insect nervous system, the embryonic development of the peripheral nervous system in the grasshopper Schistocerca gregaria was characterized...

...Guy Tear; Michael Akam; Alfonso Martinez-Arias Using sequence homology to Drosophila homeobox-containing genes, we have cloned a homologue of abdominal-A from the locust Schistocerca gregaria . The Schistocerca clone encodes a stretch of 78 amino acids including the homeodomain and its flanking...

... with that of the more primitive short germ band insects like the locust Schistocerca gregaria and by obtaining and studying locust homologues of Drosophila segmentation and homeotic genes. Metamerization in insect embryos is tightly linked to the establishment of a body plan and can be divided into two processes...
