摘　要：

漆酶(laccase) 是一类含有铜离子的多酚氧化酶，广泛存在于细菌、真菌、昆虫和植物等生物中，作用底物多样，可在有氧的情况下催化底物发生氧化还原。植物漆酶蛋白家族成员众多，功能多样，主要以催化木质素单体聚合的方式，参与植物次生细胞壁形成，对植物的生长发育具有重要作用。近年来植物漆酶及其生物学功能备受关注，本综述从植物漆酶蛋白家族成员的种类、基因表达调控、蛋白质结构特征、生化反应机制，以及生物学功能等方面，详细介绍植物漆酶家族的研究进展，为深入研究植物漆酶的功能、作用机制及其应用提供信息。

Abstract:

Laccases are phenol oxidases with copper ions, and widely present in various species such as bacteria, fungi, insects, and plants. Laccases can act on multiple substrates, and catalyze the redox of substrates under aerobic conditions. The plant laccase family has many members and diverse functions, mainly catalyzing the polymerization of lignin monomers and participating in the formation of secondary cell walls, and it plays a vital role in plant growth and development. Plant laccases and their biological functions have attracted much attention in recent years. In this review, we detail the research progress of the plant laccases family from the aspects of the gene expression regulation, protein structure characteristics, biochemical reaction mechanism, and biological function, thereby providing information for further study on the plant laccase function, mechanism, and application.
