摘要 銀杏是一種含有豐富內生菌和次生代謝產物的藥用植物。近年來,國內外學者對銀杏內生菌進行了較多的研究,從銀杏的根、莖、葉、種子等部位分離出多種不同的內生菌,通過培養發酵、分離、純化和鑒定,獲得了多樣化的次生代謝產物,如黃酮、萜類化合物等。這些化合物具有抗菌、抗氧化和抗病蟲害等功能,在生物防治領域展現了良好的應用前景。綜述了銀杏內生菌及其次生代謝產物的多樣性,并對其生物防治研究現狀進行了總結,以期為銀杏內生菌資源的開發利用提供參考。
關鍵詞 銀杏;內生菌;次生代謝產物;多樣性;生物防治

Abstract Ginkgo biloba is a medicinal plant rich in endophytes and secondary metabolites. In recent years,scholars at home and abroad have conducted more research on Ginkgo biloba endophytes,isolated a variety of different endophytes from the roots,stems,leaves,seeds and other parts of Ginkgo biloba,and obtained a variety of secondary metabolites,such as flavonoids and terpenoids,through culture fermentation,separation,purification and identification. These compounds have antibacterial,antioxidant and anti-pest and disease functions,and show good application prospects in the field of biological control. In this paper,the diversity of endophytes and their secondary metabolites was reviewed,and the research status of their biological control was summarized,in order to provide a reference for the development and utilization of endophytes in Ginkgo biloba.
Key words Ginkgo biloba;Endophytic bacteria;Secondary metabolites;Diversity;Biological control

植物內生菌(endophyte)是一類特殊的微生物,生活于植物組織、器官中,與植物共生,通常不會引起植物疾病,主要包括內生真菌、內生細菌和內生放線菌[1]。在各種植物的不同部位,包括木本和草本植物、單子葉和雙子葉植物[2],都存在內生菌,這些內生菌在寄主植物生長和發育過程中起著重要的作用,包括幫助宿主植物吸收營養物質,保護宿主對抗病原體,免受病原菌的侵害,有助于植物在不同的環境中更好的生存等。……
