METHOD FOR MODIFYING THE INFLORESCENCE ARCHITECTURE OF PLANTS

摘要

The invention relates to a method for modifying the inflorescence architecture of plants, comprising: the transformation of plant material with a gene construction containing a cytotoxic gene under the control of the PsEND1 pea anther-specific gene promoter; the regeneration of the plants; and the selection of the transgenic plants that exhibit a modified inflorescence architecture compared to that of the corresponding wild plant. The resulting transgenic plant exhibits a more complex branching pattern with a greater number of branches and higher order branches, all of which are flowering. The invention is suitable for use in agriculture, particularly in the production of ornamental plants
