    摘要: The invention provides a method to regulate expression of a gene of interest in a plant comprising, introducing into the plant a first nucleotide sequence comprising, the gene of interest operatively linked to a first regulatory region, and an operator sequence capable of binding a fusion protein, and a second nucleotide sequence comprising a second regulatory region in operative association with a nucleotide sequence encoding the fusion protein. The fusion protein comprising, a DNA binding protein, or a portion thereof, capable of binding the operator sequence, and a recruitment factor protein, or a portion thereof, capable of binding a chromatin remodelling protein. In this manner, expression of the second nucleotide sequence produces the fusion protein that regulates expression of the gene of interest.

    摘要: A method for altering the level of one or more carotenoids in a plant or a tissue within the plant is provided. Method comprises introducing a nucleic acid sequence comprising a regulatory region operatively associated with a silencing nucleotide sequence that reduces or eliminates the expression of a lycopene epsilon cyclase into the plant, and expressing the silencing nucleotide sequence. Expression of the sequence reduces the level of the lycopene epsilon cyclase in the plant or within a tissue of the plant, and results in altering one or more carotenoids.

    摘要: The invention provides a method for selectively controlling the transcription of a gene of interest, comprising producing one or more plants that express either a first, a second, or both the first and second genetic constructs. The first genetic construct comprises a first regulatory region operatively linked to a gene of interest and at least one repressor sequence capable of controlling the activity of the first regulatory region. The second genetic construct comprises a second regulatory region in operative association with a nucleic acid molecule, or a derivative thereof, encoding a repressor protein, the repressor protein exhibiting both repressor operator sequence binding activity and repressor activity.

The first genetic construct comprises a first regulator region operatively linked to a gene of interest and at least one repressor sequence capable of controlling the activity of the first regulatory region.

The first and second genetic constructs may reside on separate vectors, or the vector may comprise both the first and second genetic constructs comprised as just defined. If the first and second constructs reside within separate plants, then the first plant and the second plant are crossed to obtain progeny, so that the progeny comprise both the first genetic construct and the second genetic construct. The progeny of this cross are characterized in that the expression of the second genetic construct represses expression of the gene of interest. The first and second regulatory regions may be either the same or different and may be selected from the group consisting of a constitutive promoter, an inducible promoter, a tissue specific promoter, and a developmental promoter. if the plant comprises the vector that comprises both the first and second genetic construct, or if a plant has been co-transformed with the first and second genetic construct so that both the first and second genetic constructs may be expressed in the same plant, then it is preferred that the first and second regulatory regions are different. The first regulatory region may comprise a constitutive promoter, an inducible promoter, a tissue specific promoter, or a developmental promoter. The second regulatory region may comprise an inducible promoter, a tissue specific promoter, or a developmental promoter.

    摘要: A method for reducing the level of one or more than one protein in a plant or a tissue within the plant, and plants with reduced levels of target proteins are provided. The method involves introducing a nucleic acid sequence into the plant, where the nucleic acid sequence comprises a regulatory region operatively associated with a silencing nucleotide sequence. The expression of the silencing nucleotide sequence reduces or eliminates the expression of two or more than two enzymes involved in the synthesis of the one or more than one protein. The reduced level of the one or more than one protein may be determine by comparing the level of the one or more than one protein in the plant, or a tissue of the plant, with a level of the one ore more than one protein in a second plant, or the tissue from the second plant, that does not express the nucleic acid sequence. Plants and seeds obtained from plants with reduced levels of target proteins, and reduced anti-nutrient factors are also provided
