This application is a National Stage application under 35 U. Provisional Application Ser. Funding for the work described herein was provided by the federal government U. Department of Energy Grant No. The material on the accompanying diskette is hereby incorporated by reference into this application.
The accompanying compact discs contain one file, WO1—Sequence.
The file named WO1—Sequence. This document relates to methods and materials involved in modulating e. For example, this document provides plants having a decreased amount of lignin as well as materials and methods for making plants having a decreased amount of lignin.
Phenylpropanoids are plant-derived organic compounds that are biosynthesized from the amino acid phenylalanine. Intermediates and end products of this pathway include compounds having important roles in plants, such as phytoalexins, antiherbivory compounds, antioxidants, ultra-violet protectants, pigments, and aroma compounds. The majority Saccharu, the carbon in the pathway, however, is channeled toward the synthesis of lignin. Angiosperm lignin is composed of three main units named p-hydroxyphenyl Hguaiacyl Gand syringyl S units. These components originate from the polymerization of three monolignols, p-coumaryl, coniferyl, and sinapyl alcohols, respectively.
Fagus Grandifolia And Acer Saccharum Case Study
The monolignols are synthesized from phenylalanine through successive deamination, reduction, hydroxylation, and methylation steps. The proportions of H, G, and S units in the cell wall vary according to plant species and tissue type. As a major polymer of cell walls, lignin has a direct impact on the characteristics of plants and plant products, such as wood.
Highly lignified wood is durable and therefore a good raw material for many applications. Since lignin yields more energy when burned than cellulose, lignified wood is also Economicallj excellent fuel.
The mechanical support provided by lignin prevents lodging, a problem in many agronomically important plants. On the other hand, lignin is detrimental to paper manufacture and must be removed from pulp before paper can be manufactured. This is costly both in terms of energy and the environment.]
