The present invention relates to the modification of fructan biosynthesis in plants and, more particularly, to enzymes involved in the fructan biosynthetic pathway and nucleic acids encoding such enzymes. The present invention also relates to regulatory elements and, more particularly, to promoters capable of causing expression of an exogenous gene in plant cells, such promoters being from a gene encoding an enzyme involved in the fructan biosynthetic pathway in plants. The invention also relates to vectors including the nucleic acids and regulatory elements of the invention, plant cells, plants, seeds and other plant parts transformed with the regulatory elements, nucleic acids and vectors, and methods of using the nucleic acids, regulatory elements and vectors.
