Abstract excerpt

We reported previously that the plant oncogene rolD anticipates and stimulates flowering in Nicotiana tabacum, and encodes ornithine cyclodeaminase, an enzyme catalysing the conversion of ornithine to proline. To investigate on the possible role of proline in flowering, we altered the expression of AtP5CS1, encoding the rate-limiting enzyme of proline biosynthesis in plants. Accordingly we characterized a mutant...
