Metodo para modificar geneticamente una planta para incrementar la produccion de un producto biosintetico en un tejido deseado; y metodo para modificar geneticamente una planta que tiene deposicion de lignina que es sustancialmente localizada en los vasos de tejido de xilema de la planta

摘要

The invention provides methods of engineering plants having lignin deposition or xylan deposition that is substantially localized to the vessels of xylem tissue in the plant. The invention also provides methods of engineering plants to increase production of a desired biosynthetic product, e.g., to have increased secondary cell wall deposition or increased wax/cutin accumulation. The engineered plants of the present invention have use in bioenergy production, e.g., by improving the density and the digestibility of biomass derived from the plant and to improve water usage requirements.
