New Drosophila transgenic reporters: insulated P-element vectors expressing fast-maturing RFP.
In vivo green fluorescent protein (GFP)/red fluorescent protein (RFP) double-labeling studies have been hampered by several inconvenient properties of DsRed, the first described RFP. These disadvantages include a very slow (> 24 h) maturation time, emission of contaminating green light, and low solubility. A recently developed variant of DsRed, called DsRed.T4, has a much shorter maturation tim...
متن کاملVector-dependent gene expression driven by insulated P-element reporter vectors.
The Pelican and Stinger series of P-element transformation vectors are a popular choice for reporter gene expression in transgenic flies. We report here as a cautionary note that these vectors on their own can drive reporter gene expression in the larval and pupal salivary gland.
متن کاملInsulated piggyBac vectors for insect transgenesis
BACKGROUND Germ-line transformation of insects is now a widely used method for analyzing gene function and for the development of genetically modified strains suitable for pest control programs. The most widely used transposable element for the germ-line transformation of insects is piggyBac. The site of integration of the transgene can influence gene expression due to the effects of nearby tra...
متن کاملTargeting of P-Element Reporters to Heterochromatic Domains by Transposable Element 1360 in Drosophila melanogaster.
Heterochromatin is a common DNA packaging form employed by eukaryotes to constitutively silence transposable elements. Determining which sequences to package as heterochromatin is vital for an organism. Here, we use Drosophila melanogaster to study heterochromatin formation, exploiting position-effect variegation, a process whereby a transgene is silenced stochastically if inserted in proximity...
متن کاملVectors for P element-mediated gene transfer in Drosophila.
We have constructed and tested several new vectors for P element-mediated gene transfer. These vectors contain restriction sites for cloning a wide variety of DNA fragments within a small, non-autonomous P element and can be used to efficiently transduce microinjected DNA sequences into the germ line chromosomes of D. melanogaster. The P element in one vector also carries the rosy gene which se...
