| Abstract: | The regulation of tuber formation and tuber sprouting are compared. As a starting point it is hypothesized that these two phenomena are opposite to each other. This idea is tested from three points of view: hormonal regulation, gene expression, and carbohydrate metabolism. It is concluded that there is only limited evidence to support the hypothesis. On the contrary, several examples are given indicating that similar mechanisms might be operative during tuber formation and tuber sprouting. |
