木质素是木材的主要成分，是生产纸浆和纸张的最广泛使用的原料。虽然生物化学和分子生物学基础的木质素生产更好地理解比他们的其他木材成分，最近的工作促使了一些重新评估的木质素生物合成途径。这些修订所依据的一些工作涉及对具有修饰的木质素生物合成的转基因植物的调查。除了它们在阐明木质素生物合成途径方面的价值之外，还正在生产这样的转基因植物，目的是改进用于纸浆和纸张生产的植物原料。这篇综述介绍了基因工程如何产生新的见解如何木质素生物合成途径的运作，并表明，木质素可以改善，以促进制浆。本文介绍了当前造纸技术的发展现状，并讨论了木质素改性对纸浆生产的影响。木质素含量、组成或两者的微调改性现在是可实现的，并且可以具有重要的经济和环境效益。
Lignin is a major component of wood, the most widely used raw material for the production of pulp and paper. Although the biochemistry and molecular biology underpinning lignin production are better understood than they are for the other wood components, recent work has prompted a number of re-evaluations of the lignin biosynthetic pathway. Some of the work on which these revisions have been based involved the investigation of transgenic plants with modified lignin biosynthesis. In addition to their value in elucidating the lignin biosynthetic pathway, such transgenic plants are also being produced with the aim of improving plant raw materials for pulp and paper production. This review describes how genetic engineering has yielded new insights into how the lignin biosynthetic pathway operates and demonstrates that lignin can be improved to facilitate pulping. The current technologies used to produce paper are presented in this review, followed by a discussion of the impact of lignin modification on pulp production. Fine-tuned modification of lignin content, composition, or both is now achievable and could have important economic and environmental benefits.
