The metabolic engineering of primary metabolism provides an enormous potential to improve the value of plant-based raw materials for food and industrial applications. This chapter focuses on the current progress in the manipulation of carbohydrate and lipid biosynthesis in transgenic starch and oilseed crops, respectively. In most approaches, the manipulation of the biosynthetic routes revealed limitations and bottlenecks in the pathways, and we discuss how the gain of knowledge led to improved strategies to circumvent these restrictions. We summarize recent advances in improving starch yield as well as starch quality, i.e. the ratio of amylopectin to amylose, for particular industrial uses, and we present the strategies to produce novel beneficial carbohydrates in crops. We also describe the numerous approaches to obtain high value plant oil by the targeting of unusual fatty acids into the seed oil of oilseed crops by introducing biosynthetic enzymes of exotic species in order to improve the suitability of the engineered vegetable oil as renewable resource for biofuel production, as chemical feedstock and for food and feed. Finally, we briefly discuss recent successful examples to engineer plant secondary metabolism to enhance plant nutritional value
