| Abstract: | Potatoes can be used in many different ways, but most involve the use of fresh tubers. Because producing fresh potatoes throughout the year is unfeasible, long-time storage is essential. Unlike cereal seeds, tubers are not dehydrated and active metabolism occurs. Consequently, sprout growth is initiated following a period of endodormancy. Therefore, controlling the length of the dormancy period is of considerable economic importance. New strategies are needed because current cold storage techniques or treatment with sprout inhibitors are often problematic. Recently, an interesting alternative approach has been developed involving the production of genetically engineered potatoes with altered metabolic pathways to prolong the dormancy period of the harvested tuber. |
