An isolated DNA molecule for enhancing gene expression of a coding sequence, fragment, genetic variant, cassette, vector, cell, plant and seed containing said molecule, wherein the molecule comprises introns for induce an increase in the expression level of a transgene, useful in DNA constructions for transforming plant cells, wherein the cell or plant has a construction containing one of these introns under control of a promoter and upstream of a coding sequence stably integrated in its genome displaying higher expression levels as compared to non-transformed cells or plants, or cells or plants transformed with constructions that lack the inventive intron, wherein the sequences of 5′-non-coding sequences of the genes mentioned above also comprise promoters and exonic sequences in DNA constructions displaying synergism with the effect produced by the intron, and wherein the 5′-non-coding sequences of COX5-c genes lacking said intron promote tissue-specific expression in pollen when they are comprised in DNA constructions for plant transformation.
An isolated DNA molecule comprising SEQ ID NO:3, wherein SEQ ID NO:3 is operably linked to a promoter that is heterologous thereto, and a coding sequence.
An expression cassette comprising a promoter sequence linked to SEQ ID NO:3, which is operably linked to a coding sequence, wherein said promoter sequence is heterologous to SEQ ID NO:3 and wherein said SEQ ID NO:3 increases the expression level of the coding sequence in plant cells compared to plant cells transformed with an expression cassette comprising the promoter sequence operably linked to the coding sequence and lacking the polynucleotide of SEQ ID NO:3.
A plant cell transformed with an expression cassette comprising a promoter sequence linked to SEQ ID NO:3, which is operably linked to a coding sequence, wherein said promoter sequence is heterologous to SEQ ID NO:3 and wherein said SEQ ID NO:3 increases the expression level of the coding sequence in the plant cell compared to a plant cell transformed with an expression cassette comprising the promoter sequence operably linked to the coding sequence and lacking the polynucleotide of SEQ ID NO:3.
A transgenic plant transformed with an expression cassette comprising a promoter sequence linked to SEQ ID NO:3, which is operably linked to a coding sequence, wherein said promoter sequence is heterologous to SEQ ID NO:3;
A transgenic seed transformed with an expression cassette comprising a promoter sequence linked to SEQ ID NO:3, which is operably linked to a coding sequence, wherein said promoter sequence is heterologous to SEQ ID NO:3;
