    摘要: The present invention relates to a method for producing a gene product by expressing a gene encoding said gene product in angiosperm host cells, which method comprises: a) constructing a vector expressible in angiosperm host cells, said vector comprising a promoter region derived from an amylase gene selected from SBAmyA, SBAmyB, SBAmyC genes or SBAmyD of the sugar beet and a gene encoding a desired gene product; b) transforming a compatible angiosperm host cell with said vector; c) cultivating the resulting transformant host cell to a sugar-depleted or sugar-free condition to promote the expression of said gene under the control of such promoter region; and d) recovering the product of the expressed gene. The sugar beet gene when incorporated into a dicot seed or plant has improved biological properties. The gene sequences and the products thereof are claimed.
