【摘要】 以往 ,抗生素的主要来源是土壤微生物 ;而今 ,植物内生菌这一多样性十分丰富却尚未开发的微生物类群看来是一巨大资源。植物内生菌是生活于植物组织间隙的微生物 (主要是真菌和细菌 )。其中一些内生菌可能会产生在微生物 -宿主关系中发挥作用的生理活性物质 (如 :抗细菌 ,抗真菌 ,抗病毒物质等 )。鉴于这些次级代谢产物在自然界中所起的重要作用 ,对于它们在医药 ,农业 ,工业领域的应用越来越受到人们的关注。全球范围分离植物内生菌及其天然产物的工作正在展开。本文主要概述了植物内生菌及其生理活性物质研究的最新进展 ,希望以此使人们更好的认识到它们对于人类的重要性及价值。更多还原

【Abstract】 In the past,the major source of antimicrobial agents came from soil-borne microorganisms. It now appears that an enormous,relatively untapped source of microbial diversity is the microbial endophytes. By definition,these microorganisms (mostly fungi and bacteria) live in the intercellular spaces of plant tissues. Some of these endophytes may produce bioactive (antibacterial,antifungal,antiviral,etc.) substances that may be involved in the host-endophyte relationship. As these secondary metabolites may play an important role in nature,they are now attracting more attention to their application in medicine,agriculture and industry. A worldwide scientific effort to isolate endophytes and study their natural products is now underway. This review discussed the recent advances on studying endophytes and their associated bioactive products,to build a better understanding of the importance and value they have to humans.更多还原
