植物内生菌是与植物协同进化的一大类微生物种群,具有抵抗病原微生物、促进宿主生长、产与宿主相似的次生代谢物等多种有益特性,是宝贵的生物资源库。盾叶薯蓣具有很高的药用价值,也是多种激素类药物合成前体的主要植物来源。从盾叶薯蓣植物分离具有有益特性的内生菌成为近年内生菌研究的热点。本文从盾叶薯蓣内生菌的分离鉴定方法和盾叶薯蓣内生菌的特性两个方面概述了近年来盾叶薯蓣内生菌的研究现状,以期为盾叶薯蓣内生菌的进一步研究开发提供参考。
Plant endophytes are a large group of microorganisms that co-evolve with plants. They have many beneficial properties such as resistance to pathogenic microorganisms, growth promotion of hosts, production of secondary metabolites similar to hosts, and are valuable biological resource pools. Dioscorea zingiberensis has a high medicinal value, but also a major source of plant precursors for a variety of hormone drugs. Endophyte isolated from Dioscorea zingiberensis plants with beneficial properties has become a hot spot in endophyte research in recent years. In this paper, the isolation and identification methods of endophyte from Dioscorea zingiberensis and the characteristics of endophyte Dioscorea zingiberensis.In this paper, the research status of endophyte dioscorea in Dioscorea zingiberensis in recent years is summarized in order to further study and develop endophyte Dioscorea nipponica for reference.
