Abstract | The gene of the construct pTOM5 is involved in the carotenoid pathway, which produces carotenes, lutein, xanthophylls, and pigments such as lycopene. The invention proposes to modify (inhibit or promote) the synthesis of such compounds in plants using novel DNA contructs comprising a DNA sequence homologous to some or all of the gene encoded by the clone pTOM5, preceded by a plant promoter. In particular, colour of plant parts, especially fruit, may be modified. Yellow tomatoes are disclosed. |
