Endophytic bacteria have been found in virtually every plant studied, where they colonize the internal tissues of their host plant and can form a range of different relationships including symbiotic, mutualistic, commensalistic and trophobiotic. Most endophytes appear to originate from the rhizosphere or phyllosphere; however, some may be transmitted through the seed. Endophytic bacteria can promote plant growth and yield and can act as biocontrol agents. Endophytes can also be beneficial to their host by producing a range of natural products that could be harnessed for potential use in medicine, agriculture or industry. In addition, it has been shown that they have the potential to remove soil contaminants by enhancing phytoremediation and may play a role in soil fertility through phosphate solubilization and nitrogen fixation. There is increasing interest in developing the potential biotechnological applications of endophytes for improving phytoremediation and the sustainable production of nonfood crops for biomass and biofuel production.
几乎在每一种被研究的植物中都发现了内生细菌，它们在宿主植物的内部组织中定殖，并能形成一系列不同的关系，包括共生、互利共生、偏利共生和营养共生。大多数内生菌似乎起源于根际或叶际；然而，有些可能通过种子传播。内生细菌可以促进植物生长和提高产量，并能作为生物防治剂。内生菌还可以通过产生一系列天然产物对宿主有益，这些天然产物可用于医药、农业或工业。此外，研究表明它们有通过增强植物修复来去除土壤污染物的潜力，并且可能通过溶解磷酸盐和固氮在土壤肥力方面发挥作用。人们对开发内生菌的潜在生物技术应用越来越感兴趣，以改善植物修复以及用于生物质和生物燃料生产的非粮食作物的可持续生产。
