RESUMO
As part of a more detailed study on plant tumorigenesis, the action of gibberellic acid (GA3) in wounded potato tuber tissues as a model system has been evaluated. GA3 stimulates total RNA synthesis in wounded tissues, the optimal concentration being 0.1 micromolar. The responsiveness of the tissue toward the hormone develops with time after wounding. Whereas freshly wounded tissue does not respond at all to the hormone, it becomes competent after about 6 hours, the competence being maximal after 1 day of wound healing.
