摘要： Methods and compositions are provided for targeting a polypeptide of interest to a chloroplast. Recombinant polynucleotides comprising a nucleotide sequence encoding a chimeric chloroplast transit peptide (CTP) operably linked to a heterologous polynucleotide of interest are provided. In specific embodiments, the chimeric CTP comprises an N-terminal domain operably linked to a central domain operably linked to a C-terminal domain of a CTP to form a chimeric chloroplast transit peptide having CTP activity. Recombinant polypeptides encoding the same, as well as, cells, plant cells, plants and seeds are further provided which comprise the recombinant polynucleotides. Methods of use of the various sequences are also provided.

摘要： Methods and compositions are provided which employ a silencing element that, when ingested by a pest, such as a Coleopteran plant pest or a Diabrotica plant pest, decrease the expression of a target sequence in the pest. In specific embodiments, the decrease in expression of the target sequence controls the pest and thereby the methods and compositions are capable of limiting damage to a plant. The present invention provides various target polynucleotides set forth in any one of SEQ ID NOS: 1-236 or active variants and fragments thereof, wherein a decrease in expression of one or more the sequences in the target pest controls the pest (i.e., has insecticidal activity). Further provided are silencing elements which when ingested by the pest decrease the level of the target polypeptide and thereby control the pest. In specific embodiment, the pest is D. virgifera virgifera, D. barberi, D. speciosa, or D. undecimpunctata howardi. Plants, plant part, bacteria and other host cells comprising the silencing elements or an active variant or fragment thereof of the invention are also provided.

摘要： The present invention provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions include a novel nucleotide sequence for a root-preferred promoter for the gene encoding CRWAQ81. A method for expressing a heterologous nucleotide sequence in a plant using the promoter sequences disclosed herein is provided. The method comprises stably incorporating into the genome of a plant cell a nucleotide sequence operably linked to the root-preferred promoter of the present invention and regenerating a stably transformed plant that expresses the nucleotide sequence.
