<p>The invention relates to a method for enabling rooting or grafting of a plant which contains in its genome a gene which is placed under the regulation of an inducible promoter and which codes for a rooting-inhibiting product or a product leading to rooting inhbition, comprising of treating the plant prior to production of a cutting or graft or treating the cutting or graft after production of the cutting or graft with a substance which either discontinues the effect of the rooting-inhibiting gene; and/or results in expression of a second gene likewise present in the plant which is under the regulation of an inducible promoter and the expression product of which discontinues the effect of the rooting-inhibiting gene. The invention further relates to a transgenic plant which is provided with a mechanism for rooting inhibition and a mechanism which discontinues rooting inhibition, and to a DNA construct for effecting the discontinuation of rooting inhibition.</p> |
