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.
