...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...

.../ Summary: Expression and functional studies in hide beetles suggest independent roles for pair-rule genes in elongation and segmentation of sequentially segmenting insects, and rewiring of a subset of these regulatory genes. Segmentation Germband elongation Pair-rule gene Dermestes Beetle Evo...

...Mark D. Schroeder; Christina Greer; Ulrike Gaul The generation of metameric body plans is a key process in development. In Drosophila segmentation, periodicity is established rapidly through the complex transcriptional regulation of the pair-rule genes. The ‘primary’ pair-rule genes generate...

... decrease in cell size. Our results indicate that lilli represents a novel pair-rule gene that acts in cytoskeleton regulation, segmentation and morphogenesis. * Authors for correspondence (e-mail: [email protected] and [email protected] ) 18 12 2000 07 02 2001...

...David Kosman; Stephen Small ABSTRACT The asymmetric distribution of the gap gene knirps ( kni ) in discrete expression domains is critical for striped patterns of pair-rule gene expression in the Drosophila embryo. To test whether these domains function as sources of morpho-genetic activity...

... to somites occurs between the marginal expression domain and the first expression band, anterior to it. Moreover, the her1 bands, and the intervening non-expressing zones, each represents the primordium of a somite. This expression pattern is highly reminiscent of that of Drosophila pair-rule genes...

... function in the pathway of Drosophila segmentation. Transient over-expression of runt under the control of a Drosophila heat-shock promoter caused stripe-specific defects in the expression patterns of the pair-rule genes hairy and even-skipped but had a more uniform effect on the secondary pair-rule gene...

... the regulation of ftz . We have produced ttk protein ectopically in blastoderm-stage embryos transformed with a heat shock - ttk construct. Ectopic ttk caused complete or near-complete repression of the endogenous ftz gene, as well as significant repression of the pair-rule genes even skipped, odd skipped, hairy...

... to the larval cuticle. Cell death is not limited to those cells that would normally express ftz + , suggesting that it is some indirect consequence of the abnormal situation in the mutant embryo. 25 07 1988 © 1988 by Company of Biologists 1988 Drosophila pair-rule gene fushi tarazu...

...Ken Howard ABSTRACT The first indication of the formation of segment primordia in Drosophila is expression of the segment-polarity genes in particular parts of each primordium. These patterns are controlled by another class of genes, the pair-rule genes, which show characteristic two-segment...
