A method of producing a plant with switchable starch-synthesising ability comprises stably incorporating into the genome of a recipient plant at least one target gene encoding an enzyme involved in a starch or glycogen biosynthetic pathway and under the control of a gene switch. A plant with switchable starch-synthesising ability may have switchable starch yield, and/or switchable starch quality. Starch or glycogen biosynthetic enzymes include soluble starch synthase, branching enzyme, glycogen synthase, ADP-glucose pyrophosphorylase, self-glucosylating protein, glycogenin and amylogenin. DNA constructs for use in this method are described, as well as plants transformed with said DNA constructs, the seeds and progeny of such plants, and hybrids whose pedigree includes such plants. |
