.... In Drosophila , embryos mutant for giant show a gap in the anterior as well fusions of several abdominal segments. In Tribolium , a short germ beetle, giant is required for segmental identity, but not formation, in gnathal segments and also for segmentation of the entire abdomen. This raises the possibility...

... of the syncytial blastoderm embryo. Patterning defects in Dm'Kr mutants are centred symmetrically around its bell-shaped expression profile. We have analysed the role of Krüppel in the short-germ beetle Tribolium castaneum where the pair-rule stripes corresponding to the 10 abdominal segments arise during growth...
