"The process to obtain a plant with caracteru00ecsticas growth changed or altered architecture, chimeric gene, plant cell, plant, seed of the same fragment isolated from the DNA, and,Uses of a proteu00ecna that controls cell division, and a DNA encoding the same ''.A process is provided for modifying the growth or the architecture of plants by altering the level or the functional level of a protein that controls cell division.Preferably a protein of control of cell division that connects or phosphorylates proteins similar to retinoblassoma, more preferably a cyclin.A particularly cyclin type D within the cells of a plant.Also are provided that comprise a chimeric genes transcribed region of DNA, which encodes an RNA or a protein.When expressed increases or decreases the level or the functional level of a protein that controls cell division and plant cells and plants expressing these fusion genes.
