摘　　要：木质素是植物次生壁的主要成分,在维管植物中木质素起抗压、防害虫和病菌侵入、运输水分等作用。其含量和组分限制了人们利用木质纤维素,并且严重影响了农艺性状,生物燃料的生产和造纸工业的生产。为了能更好的利用木质纤维素和提高生产效率,论述了最新木质素的生物合成途径,并指出了木质素合成途径对木质素基因工程的利用前景。Lignin is a major component of plant secondary cell walls.In vascular plants,lignin fulfills several vital functions that include leading mechanical strength and structural support,acting as physical barrier to pests and pathogens,and providing the key hydrophobic component of vascular tissues.The content and/or composition of lignin often limit the properties of the lignocellulosic biomass for human use.It affects agricultural traits,biofuel production,and the pulping industry.In this review,we provide an overview of the current understanding of lignin biosynthesis pathway and discuss the prospect of genetic engineering of lignin biosynthesis.
