摘要:

种子作为植物重要的繁殖器官,是多种有益微生物的载体,其内部普遍存在种类丰富多样且对植物具有一定作用的内生菌群落。种子内生细菌可以直接或间接地促进种子萌发和植物生长、提高植物对各种病原菌和环境胁迫的抗性、促进活性成分产生和累积,并产生各种生物学效应,它们的分布和种群结构受寄主植物的遗传特性和健康状况以及周围环境生态的影响。本文从种子内生细菌的多样性,种子内生细菌促进植物生长、提高植物抗性、促进活性成分累积以及在农业生产和生物防治方面的应用前景,对种子内生细菌研究领域所取得的进展进行论述并提出展望,为后续种子内生细菌相关研究提供参考。

Abstract:

As an important reproductive organ of plants, seeds are the carriers of a variety of beneficial microorganisms, and there are endophytic communities with rich and diverse species as well as certain effects on plants. Seed endophytic bacteria can directly or indirectly promote seed germination and plant growth, improving plant resistance to various pathogens and environmental stresses, promoting the production and the accumulation of active ingredients, and produce various biological effects. Their distribution and population structure are affected by the genetic characteristics and health status of host plants and the ecology of the surrounding environment. In this paper, the progress in the research field of seed endophytic bacteria was discussed and prospected from the diversity of seed endophytic bacteria, seed endophytic bacteria promoting plant growth, improving plant resistance, promoting the production and the accumulation of active ingredients, and the application prospect in agricultural production and biological control, so as to provide reference for the follow-up research of seed endophytic bacteria.
