Abstract
A modular promoter construct is described which possesses a promoter which is active in plant cells and a DNA sequence from exon 1 of the rice actin 1 gene. This modular promoter construct gives rise, where appropriate together with additional regulatory DNA sequences, to a substantial increase in gene expression in plant cells.
Claims8
A modular promoter construct, comprising a promoter which is active in plant cells and a DNA sequence of at least 30 bases from exon 1 of the rice actin 1 gene, or derivatives of this modular promoter construct which have promoter activity, wherein said promoter is not a rice actin 1 gene promoter.
A vector comprising a promoter construct which comprises a promoter which is active in plant cells and a DNA sequence of at least 30 bases from exon 1 of the rice actin 1 gene, or derivatives of this modular promoter construct which have promoter activity, wherein said promoter construct is coupled to a gene which is expressed in a plant cell, and wherein said promoter is not a rice actin 1 gene promoter.
A plant cell which is transformed with a vector comprising a promoter construct which comprises a promoter which is active in plant cells and a DNA sequence of at least 30 bases from exon 1 of the rice actin 1 gene, or derivatives of this modular promoter construct which have promoter activity, wherein said promoter construct is coupled to a gene which is to be expressed in a plant cell, and wherein said promoter is not a rice actin 1 gene promoter.
A plant or its descendants, regenerated from a plant cell comprising a promoter construct which comprises a promoter which is active in plant cells and a DNA sequence of at least 30 bases from exon 1 of the rice actin 1 gene, or derivatives of this modular promoter construct which have promoter activity, wherein said promoter construct is coupled to a gene which is to be expressed in a plant cell, and wherein said promoter is not a rice actin 1 gene promoter.
A method for preparing plants having elevated gene expression, said method comprising transforming a plant cell with a vector comprising a promoter construct which comprises a promoter which is active in plant cells and a DNA sequence of at least 30 bases from exon 1 of the rice actin 1 gene, or derivatives of this modular promoter construct which have promoter activity, wherein said promoter construct is coupled to a gene which is to be expressed in a plant cell, and wherein said promoter is not a rice actin 1 gene promoter.
