Abstract
A thermostable glucose isomerase was expressed in Solanum tuberosum Desirée using the tuber-specific granular-bound starch synthase promoter. The fructose content was substantially increased in microtubers, greenhouse grown tubers as well as tubers produced in field trials as compared with the controls. Furthermore, the tuber yield of field grown potatoes was enhanced by 30% in the transgenic lines (from 1.04 kg/plant in the wild type to 1.36 kg/plant in the transgenic lines).
