Abstract:
An isolated regulon comprising a DNA sequence selected from genomic plant DNA located within the 5 kb region adjacent to the 5' end of the transcription start of a genomic nucleic acid which hybridizes to SEQ ID NO:1 in hybridization buffer with 50% formamide for 14 hours at 42.degree. C., followed by washing in 2.times.SSC/0.1% SDS for 20 minutes and 0. 1.times.SSC/0.1% SDS for 15 minutes at 65.degree. C., and wherein said isolated regulon constitutively expresses a gene under its control, regardless of ambient oxygen concentration, ambient temperature, or root cells' sugar concentration, and has the transcription regulatory activity of the Beta vulgaris SBSSI gene regulon, and wherein the isolated regulon is active in storage root tissue of sugar beet.
