Plants, particularly cereal plants, which have improved ability to synthesise starch at elevated or lowered temperatures and/or to synthesise starch with an altered fine structure are produced by inserting into the genome of the plant (i) a gene(s) en- coding a form of an enzyme of the starch or glycogen biosynthetic pathway, particularly soluble starch synthase and/or branch- ing enzyme and/or glycogen synthase, which display an activity which continues to increase over a temperature range over which the activity would normally be expected to decrease, and/or (ii) a gene(s) encoding sense and anti-sense constructs of enzymes of the starch biosynthetic pathway, particularly soluble starch synthase and/or branching enzyme and/or glycogen synthase, which alters the natural ratios of expression of the said enzymes or inserts enzymes with special structural characteristics which alter the natural branching pattern in starch.
