... stages subsequent to the blastoderm. We show that the previously described mutation jaws is an amorphic Tc'Kr allele. Pair-rule gene expression in the blastoderm is affected neither in the amorphic mutant nor in Tc'Kr RNAi embryos. Only during subsequent growth of the germ band does pair-rule patterning...

... was approached with 7.5 ng/μl. (E) Although morpholino oligos inhibit gene function by a different mechanism and are chemically distinct, a similar range of deletions was observed. giant Short germ Long germ Segmentation Tribolium Gap gene Abdomen Krüppel jaws Drosophila Evolution...

... a screen for mutations that alter embryonic patterning of the beetle, Tribolium castaneum . One of the mutations isolated, godzilla , affects early steps in the segmentation process in the whole animal, like Drosophila pair-rule mutants. Another mutation, jaws , is novel: it causes both a dramatic homeotic...
