Raffinose synthase genes coding for proteins capable of producing raffinose by combining a D-galactosyl group through an &#x3b1;(1&#x2192;6) bond with a hydroxyl group attached to the carbon atom at position 6 of a D-glucose residue in a sucrose molecule were isolated from various plants. These raffinose synthase genes are useful to change the content of raffinose family oligosaccharides in plants.

Raffinose synthase genes and their use

The present invention provides a promoter including the following DNA (a) or (b): (a) the DNA consisting of the nucleotide sequence of nucleotide numbers 1743 to 2301 in the nucleotide sequence represented by SEQ ID: No. 1; or, (b) the DNA which can be hybridized with said DNA (a) in a stringent condition and having a promoter function in a plant cell, and the like.
