In some cases the lignin content and composition have been altered, while in others the lignin content, as measured by traditional means, has not appreciably declined but the lignin structure has changed. Phenolic components not normally associated with lignification may be incorporated into the polymers of some deficient plants. The plasticity of lignification suggests that attempts to reduce lignin by targeting pathway enzymes will not always be successful, but provides significant opportunities to engineer the properties of lignins to allow more extensive cell wall utilization. |
