摘　　要：植物几丁质酶(chitinase)和β-1,3-葡聚糖酶(β-1,3-glucanase)能够水解病原菌细胞壁的主成分几丁质、β-1,3-葡聚糖和肽聚糖,有效抑制病原菌的生长,是植物防御系统中的两个重要的防卫因子。此外,两者还具有协同抑菌作用,被广泛应用于植物抗病基因工程。本文通过阐述植物几丁质酶和β-1,3-葡聚糖酶的结构、分类、生物学特性、表达调控机制及两者之间的协同抗病作用研究进展,为系统了解植物几丁质酶和β-1,3-葡聚糖酶的作用模式以及植物抗病遗传改良提供参考资料。Plant chitinase andβ-1,3-glucanase,two important defensive factors in the plant defense system,can hydrolyze the main components of pathogenic cell wall chitin,β-1,3-glucan and peptidoglycan,thus effectively inhibit the growth of pathogens.In addition,they also have synergistic antimicrobial effects and are widely used in plant disease resistance genetic engineering.In this paper,the research progress on the structure,classification,biological characteristics,expression regulation mechanism and the synergistic disease resistance of plant chitinase andβ-1,3-glucanase were reviewed.This study will provide references for systematically understand the action mode of plant chitinase andβ-1,3-glucanase,and for the genetic improvement of plant disease resistance.
