Pair-rule genes

Pair-rule genes—define seven bands runt (runt) hairy (h) fushi tarazu (ftz) even skipped (eve ) paired (prd) odd paired (opa)... [Pg.823]

Many of the segmentation genes that determine the periodic subdivisions of the ectoderm are also involved in generating the mesodermal A and P domains, as well as in the resulting diversification of tissues in the trunk mesoderm. For example, mutations in pair-rule genes that reduce the number of ectodermal parasegments in half also produce half the number of mesodermal parasegments. Notably, null mutations... [Pg.22]

A EXPERIMENTAL FIGURE 15-22 Gap genes and pair-rule genes are expressed in characteristic spatial patterns in early Drosophila embryos. [Pg.633]

Combinations of Cap Proteins Direct Transcription of Pair-Rule Genes in Stripes... [Pg.634]

Similar responses to gap and maternal proteins govern the striped patterns of transcription of the two other primary pair-rule genes, runt and hairy. Because the enhancers of runt and hairy respond to different combinations of regulators, the eve, runt, and hairy expression stripes pardy overlap one another, with each stripe for any one gene offset from a stripe... [Pg.635]

As we have just seen, the spatially controlled transcription of pair-rule genes sets up repeating units within the initial sheet of cells composing the early Drosophila embryo. Later, these repeating units must diversify only some of them will produce appendages, and they will specialize internally as well. This early diversification of body segments depends on the Hox genes, which are important switches that control cell identities and indeed the identities of whole parts of an animal. [Pg.636]
