Abstract: High-efficiency AAV packaging constructs and methods for their use are provided. in the present invention. These high-efficiency packaging constructs comprise an activating element (such as the P1 sequence located within the AAV S1 integration site of human chromosome 19) amplifiably linked to one or more AAV packaging genes. The constructs may be either integrated into a mammalian cell genome or maintained episomally. Use of the high-efficiency AAV packaging vectors of the invention provides for controlled amplifiable production of rAAV vector constructs.

Abstract: Methods and compositions for the expression of transgenes in monocot plants including maize are disclosed. In the invention, gene silencing is avoided by use of monocot-homeologous sequences from plants of the genus Coix for transformation. Included in these transgene sequences are Coix promoters, enhancers, coding sequences and terminators. Suitable alternatives to maize-derived transgenes are desirable for expression in maize in that homology-based gene silencing can limit or effectively eliminate transgene expression.

Abstract: Recombinant viral vectors, especially parvovirus vectors such as adeno-associated virus (AAV) vectors, capable of enhanced expression of heterologous sequences, and methods for their construction and use, are provided. The vectors have a structure, or are capable of rapidly adopting a structure, which involves intrastrand base pairing of at least one region in a heterologous sequence.
Abstract: Recombinant vectors are provided that render the proliferative response of activated lymphocytes, particularly cytotoxic T lymphocytes, of lessened dependency on T helper cells. The vectors are comprised of a region encoding a stimulatory factor polypeptide operably linked to a heterologous transcriptional control region. Expression of the stimulatory factor polypeptide from the recombinant polynucleotide in an activated lymphocyte renders the proliferative response of less dependent on lymphocyte T helper cells. When the lymphocyte is activated by binding of its cognate antigen the transcriptional control region causes transcription of the stimulatory factor encoding region. The cells containing the vector, particularly CTLs, are of use in immunotherapy.

Abstract: The present invention provides methods for increasing yield in plants by introducing a gene encoding phosphinothricin acetyltransferase. The invention further involves a method of transferring said increased yield phenotype to other lines of plants by crossing. A maize transformant is identified in which the phosphinothricin acetyltransferase gene integration event is correlated with increased yield.

Abstract: The invention provides a process to prepare a recombined transgenic Zea mays plant from a transgenic Zea mays plant, wherein the transgene in the recombinant plant has an altered genetic structure relative to the genetic structure of the transgene in the transgenic plant, due to recombination-mediated transgene deletion.
Abstract: A description of artificial transcription factors (ATFs) is provided having a non-peptidic-DNA binding domain, flexible linker and a short synthetic effector domain. The ATFs are highly potent transcriptional modulators in vitro and in vivo. Methods for targeted manipulation of gene expression and the development of new class of pharmaceuticals are also provided.
Abstract: The present invention provides a highly-efficient method for the selection and identification of insertional mutants. In the technique, a non-selective amplification is used to isolate a plurality of insertion events from a population of individuals comprising insertion mutations. Specific insertion events can then be identified from the population by the use of gene specific probes or primers. Through the identification of mutants for a particular gene, data may be obtained regarding the function and phenotypic effects of that gene, and thereby, the gene can be employed in the creation of novel biotechnological products.

Abstract: This invention provides methods and compositions for producing high titer, substantially purified preparations of recombinant adeno-associated virus (AAV) that can be used as vectors for gene delivery. At the onset of vector production, AAV producer cells of this invention typically comprise one or more AAV packaging genes, an AAV vector comprising a heterologous (i.e. non-AAV) transgene of interest, and a helper virus such as an adenovirus. The AAV vector preparations produced are generally replication incompetent but are capable of mediating delivery of a transgene of interest (such as a therapeutic gene) to any of a wide variety of tissues and cells. The AAV vector preparations produced according to this invention are also substantially free of helper virus as well as helper viral and cellular proteins and other contaminants. The invention described herein provides methods of producing rAAV particles by culturing producer cells under conditions, such as temperature and pH, that promote release of virus.
