内生细菌几乎存在于每一种植物中，它们在宿主植物的内部组织中定殖，并可以形成一系列不同的关系，包括共生，互利，共生和营养。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。植物内生细菌具有促进植物生长和提高产量的作用，并可作为生物防治剂。内生菌也可以通过产生一系列天然产物而对其宿主有益，这些天然产物可以用于医学，农业或工业的潜在用途。此外，研究表明，它们有可能通过增强植物修复来去除土壤污染物，并可能通过溶解磷酸盐和固氮来提高土壤肥力。人们越来越有兴趣开发内生菌的潜在生物技术应用，以改善植物修复和非粮食作物的生物质和生物燃料生产的可持续生产。
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.
