Recombinant negative-strand viral RNA templates are described which may be used with purified RNA-directed RNA polymerase complex to express heterologous gene products in appropriate host cells and / or to rescue the heterologous gene in virus particles. The RNA templates are prepared by transcription of appropriate DNA sequences with a DNA-directed RNA polymerase. The resulting RNA templates are of the negative-polarity and contain appropriate terminal sequences which enable the viral RNA-synthesizing apparatus to recognize the template. Bicistronic mRNAs can be constructed to permit internal initiation of translation of viral sequences and allow for the expression of foreign protein coding sequences from the regular terminal initiation site, or vice versa.

An isolated linear nucleic acid molecule comprising in this order: a first adeno-associated virus (AAV) inverted terminal repeat (ITR), a nucleotide sequence of interest and a second AAV ITR, wherein said nucleic acid molecule is devoid of AAV capsid protein coding sequences. The said nucleic acid molecule can be applied to a host at repetition without eliciting an immune response. Methods for producing and purifying this nucleic acid molecule, and use of the same for therapeutic purposes are also provided.

Methods and constructs for the introduction of multiple genes into plants using a single transformation event are described. Constructs contain a single 5′ promoter operably linked to DNA encoding a modified intein splicing unit. The splicing unit is expressed as a polyprotein and consists of a first protein fused to an intein fused to a second protein. The splicing unit has been engineered to promote excision of all non-essential components in the polyprotein but prevent the ligation reactions normally associated with protein splicing. Additional genetic elements encoding inteins and additional proteins can be fused in frame to the 5′-terminus of the coding region for the second protein to form a construct for expression of more than two proteins. A single 3′ termination sequence, such as a polyadenylation sequence when the construct is to be expressed in eucaryotic cells, follows the last coding sequence. These methods and constructs are particularly useful for creating plants with stacked input traits, illustrated by glyphosate tolerant plants producing BT toxin, and / or value added products, illustrated by the production of polyhydroxyalkanoates in plants.

The present invention provides molecular constructs and methods for use thereof, including constructs including heterologous miRNA recognition sites, constructs for gene suppression including a gene suppression element embedded within an intron flanked on one or on both sides by non-protein-coding sequence, constructs containing engineered miRNA or miRNA precursors, and constructs for suppression of production of mature microRNA in a cell. Also provided are transgenic plant cells, plants, and seeds containing such constructs, and methods for their use. The invention further provides transgenic plant cells, plants, and seeds containing recombinant DNA for the ligand-controlled expression of a target sequence, which may be endogenous or exogenous. Also disclosed are novel miRNAs and miRNA precursors from crop plants including maize and soy.

The invention is directed to seed and seed extract compositions containing levels of a human milk protein between 3-40% or higher of the total protein weight of the soluble protein extractable from the seed. Also disclosed is a method of producing the seed with high levels of extractable human milk protein. The method includes transforming a monocotyledonous plant with a chimeric gene having a protein-coding sequence encoding a protein normally present in human milk under the control of a seed maturation-specific promoter. The method may further includes a leader DNA sequence encoding a monocot seed-specific transit sequence capable to target a linked milk protein to a storage body.

The present invention is related to a method for identifying a parvovirus mutated structural protein capable of specifically binding to a binder for an antigen, a parvovirus mutated structural protein which comprises at least one B-cell epitope heterologous to the parvovirus, a multimeric structure comprising the protein, a nucleic acid encoding the protein, a virus or cell comprising the protein, a method of preparing the protein, a medicament comprising the protein, nucleic acid or multimeric structure and its use.
