Abstract
The present invention relates to a method of isolating a promoter, which causes, in plants, permanent Mesophyll-specific expression of an operably linked encoding nucleotide sequence, for example a sequence which imparts resistance or an increase in the photosynthetic performance.
Claims1
A method of isolating a mesophyll-specific promoter sequence of a cytosolic fructose-1,6-biphosphatase from potato plants which comprises
- (a) hybridizing the genome library of a potato plant with cyFBPase cDNA (SEQ ID NO:4),
- (b) isolating positive clones, and
- (c) testing the isolated clones for promoter activity.
