摘要

Method for producing a transgenic plant with size and / or architecture air portions and non air changed, the structure of the xylem chemistry going on or composition changed, or combination of these caracteru00ecsticas, plant or plant part, isolated nucleic acid molecule, vector expressu00e3 The recombinant and cell.Polynucleotides encoding, constructions of DNA and methods are described for the modification of size, architecture, and / or non airline air portions of a plant and the modification of the structure and / or the chemical composition of the xylem of a plant. The plants are transformed with a gene encoding a transcription factor active belonging to the family Knox.The overexpression of this gene in the vascular system of the plant leads to increased overall size and architecture in both systems, air and roots transgenic.
