Manipulated Organism: Plants - Potato

---

Potatoes with altered sugar metabolism had changed levels of many metabolites, some not thought to be associated with sugar metabolism.

Inulin-storing potatoes had higher alkaloid content and pigs fed on them had reduced daily weight gain.

Potatoes genetically modified to store more starch stored less starch.

Insect-resistant transgenic potatoes had less foliage and altered levels of leaf-glycoalkaloids.

Potatoes with transgene for virus resistance were variably resistant, and some lines without the target gene nevertheless became highly resistant.
