摘要： 综述植物病原菌糖基水解酶（glycoside hydrolases, GHs）基因家族的分类、酶活功能、在病原菌中的分布特征,以及在病原菌侵染过程中发挥的作用等方面的研究进展，重点分析植物病原菌GHs在病原菌侵染过程中的作用：作为毒力因子/致病因子促进病原菌侵染、作为激发子或病原体相关分子模式（PAMPs）诱导植物免疫、将植物细胞壁分解为损伤相关分子模式（DAMPs）诱导植物免疫、特异性结合或分解病原/微生物相关分子模式（P/MAMPs）抑制植物免疫。在此基础上，总结并展望植物病原菌GHs调控植物免疫的分子机制及存在的问题，为深入研究GHs的更多功能提供参考，同时也为作物改良及病害防控策略中更好地利用这些GHs家族成员提供思路。

Abstract: This paper reviews the research progress of plant pathogen glycoside hydrolases (GHs) gene family in several aspects, including classification, enzyme activity, distribution characteristics and roles in pathogen infection. GHs’ roles in pathogen infection were focused. GHs play the role of virulence factors/pathogenic factors promoting pathogen infection and the role of elicitors or pathogen-associated molecular patterns (PAMPs) inducing plant immunity. GHs decompose plant cell walls into damage-associated molecular patterns (DAMPs) to induce plant immunity and the specific binding or breakdown pathogen/microbe-associated molecular patterns (P/MAMPs) to suppress plant immunity. On these bases, the molecular mechanism of plant pathogen GHs regulating plant immunity and existing problems were summarized.It provided reference for in-depth studies of more functions of GHs, as well as for better utilization of these GHs family members in crop improvement and disease control strategies.

Key words: plant pathogens, glycoside hydrolases, enzyme activity, distribution characteristics, functions
