Evolutionarily conserved positive and negative cis-acting elements control the blastoderm-specific expression of the Drosophila serendipity α cellularisation gene
The serendipity alpha (sry alpha) cellularisation gene is only transcribed at the blastoderm stage, when this morphogenetic event takes place. We show that a 95 bp sry alpha upstream region is sufficient for blastoderm-specific expression of a lacZ reporter gene. This region encompasses four nucleotide motifs (I-IV, 5' to 3') conserved at similar relative positions in several Drosophila species...
متن کاملSelectable Marker Gene Removal and Expression of Transgene by Inducible Promoter Containing FFDD Cis-Acting elements in Transgenic plants
Abstract Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production Background: Selectable marker gene (SMG) systems are critical for generation of transgenic crops. Transgenic crop production without using SMG is not economically feasible. However, SMGs are non-essential once an intact transgenic plant has been established. Eli...
متن کاملDistal cis-acting elements restrict expression of the CyIIIb actin gene in the aboral ectoderm of the sea urchin embryo
The distal region of the S. purpuratus actin CyIIIb gene, between -400 and -1400 nucleotides, contains at least three distinct cis-acting elements (C1R, C1L and E1) which are necessary for correct expression of fusion reporter genes in transgenic sea urchin embryos. The contribution of these elements in the temporal and spatial regulation of the gene was analyzed by single and double site-direc...
متن کاملThe Regulation of Aldehyde Oxidase in Imaginal Wing Discs of Drosophila Hybrids: Evidence for cis- and trans-Acting Control Elements.
The aldehyde oxidase (Aldox) distribution pattern was determined for wing discs of partial hybrids between D. melanogaster and D. simulans. In these animals the regulation of Aldox activity is not uniform over the disc epithelium as both cis-dominant and trans -acting control were evident in different regions of the disc. The Aldox expression was shown to be regulated by loci on the X chromosom...
