植物内生放线菌及其作为微生物农药开发的潜力

摘要

植物内生放线菌广泛存在于各种植物中，具有丰富的多样性。许多植物内生放线菌具有杀虫、杀菌及除草活性。一些植物内生放线菌还具有促进植物生长的活性。植物内生放线菌还产生结构多样的具有农药活性的次生代谢产物。植物内生放线菌具有开发成为微生物农药的潜力，其代谢产物可望为新农药的创制提供先导结构。%Endophytic actinomycetes exist broadly in diverse plants and have plentiful diversities. Many endophytic actino-mycetes show insecticidal, fungicidal, herbicidal activities. Some of the endophytic actinomycetes show plant growth promoting activities. The endophytic actinomycetes could produce diverse secondary metabolites with diverse structures and pesticidal ac-tivities. So the endophytic actinomycetes have the potential to be developed as microbial pesticides, while their secondary metabolites can be expected to provide lead structure for the creation of new pesticides.
