In one example, an activation tagging DNA construct includes a coding sequence for a transposase, a detectable reporter (such as anthocyanin regulatory genes B-Peru and C1) and a non-autonomous transposable T-DNA cassette. For example, the transposable T-DNA cassette is inserted into the detectable reporter encoding region such that the B-Peru and C1 genes express anthocyanins in a cell containing the maize activation tagging DNA construct only upon excision of the transposable cassette. Methods of generating a tagged population of maize plants include transforming a maize plant cell or tissue with the disclosed constructs.

    Abstract: The present invention provides a method and components thereof of performing genetic modification under a drug-free environment. The method comprises the steps of generating a trapped mammalian cell library by trapper constructs (including the element of piggyBac terminal inverted repeats (TIRs)), reporter constructs, and helper constructs (including a sequence of an internal ribosomal entry site (IRES)). The present art allows: (1) to target & identify the silenced loci; (2) to separate genes with low-level expression at certain differentiation stages; (3) to evaluate the efficiency of gene targeting in the silent or repressed loci. The present invention avoids the biased gene targeting observed in the prior arts, and eliminates the needs of introducing antibiotic genes into the host genome which may lead to a potential threat of drifting antibiotic resistant genes into environment.

  • Publication number: 20100281555
    Abstract: Disclosed herein is a method for marking bio-information into the genome of an organism, an organism marked with inherent bio-information by the method and a method for reading the bio-information. The method is characterized in that inherent bio-information encoded to a DNA sequence or RNA sequence is inserted into genome of organisms through a gene delivery system. Inherent bio-information is inserted into genome of organisms, thus avoiding loss by cell culture or artificial manipulation and being widely used even for organisms whose host-vector system is not provided. Based on these features, the method has the following advantages. First, inherent bio-informtion can be clearly obtained from the organisms themselves, rather than an additional means such as catalogs. Second, when organisms developed through desperate efforts are stolen, they can be tracked down and identified. Third, when serious problems occur by overuse or misuse of organisms, the origin thereof can be clearly determined.
