Although many plant-associated bacteria have beneficial effects on their host, their importance during plant growth and development is still underestimated. A better understanding of their plant growth-promoting mechanisms could be exploited for sustainable growth of food and feed crops, biomass for biofuel production and feedstocks for industrial processes. Such plant growth-promoting mechanisms might facilitate higher production of energy crops in a more sustainable manner, even on marginal land, and thus contribute to avoiding conflicts between food and energy production. Furthermore, because many bacteria show a natural capacity to cope with contaminants, they could be exploited to improve the efficiency of phytoremediation or to protect the food chain by reducing levels of agrochemicals in food crops.
尽管许多与植物相关的细菌对其宿主有有益影响，但它们在植物生长发育过程中的重要性仍被低估。更好地了解它们促进植物生长的机制，可用于粮食和饲料作物的可持续生长、生物燃料生产的生物质以及工业过程的原料。这种促进植物生长的机制可能有助于以更可持续的方式提高能源作物的产量，即使在边际土地上也是如此，从而有助于避免粮食和能源生产之间的冲突。此外，由于许多细菌具有应对污染物的天然能力，它们可被用于提高植物修复效率或通过降低粮食作物中的农用化学品水平来保护食物链。
