Abstract
Leaf-specific expression of genes in transgenic plants The present invention relates to promoters which cause, in plants, permanent leaf-specific expression of an encoding nucleotide sequence under the control of said promoters, for example a sequence which imparts resistance or an increase in the photosynthetic performance.
Claims21
A promoter which causes a leaf-specific expression, in plants, of an encoding nucleotide sequence under the control of said promoter.
A promoter as claimed in any of the preceding claims, which essentially embraces a promoter sequence of a cytosolic fructose-1,6-bisphosphatase from plants.
A promoter as claimed in any of the preceding claims, which embraces the nucleotide sequence SEQ ID NO:1;
- SEQ ID NO:2 or SEQ ID NO:3, or a functional equivalent thereof.
A method of isolating a leaf-specific promoter which comprises
- a) hybridizing a plant genome library with cytFBPase (EMBL No. X76946) cDNA,
- b) isolating positive clones and
- c) testing the isolated clones for promoter activity.
A nucleic acid sequence selected from amongst SEQ ID NO:1, 2, 3, 4 and 5, and functional equivalents thereof.
