Sustainable agriculture requires the recruitment of bacterial agents to control diverse plant diseases such as bacterial endophytes. Bacterial endophytes colonize and inhabit internal plant tissues without causing any apparent damage. Within the plant, these bacteria exert multiple beneficiary effects, including direct stimulation of plant growth by the action of phytohormones or the production of metabolites. However, bacterial endophytes also protect their plant host through biocontrol pathogens or by inducing plant innate immune system. The present work makes a systematic and in-depth review on the current state of endophytic bacterial diversity, their plant colonization strategies, and their potential roles as protective agents against plant diseases during pre- and post-harvest stages of crop productivity. In addition, an exploration of their beneficial effects on sustainable agriculture by reducing/eliminating the use of toxic agrochemicals was conducted. Finally, we propose diverse effective strategies for the application of endophytic bacteria as biological agents during both pre- and post-harvest stages, with the aim of protecting crop plants and their agricultural products.
可持续农业需要招募细菌制剂来控制多种植物病害，如内生细菌。内生细菌定殖和栖息在植物内部组织中，而不会造成任何明显的损伤。在植物体内，这些细菌通过植物激素的作用或代谢产物的产生直接刺激植物生长。然而，内生细菌也通过生物防治病原体或诱导植物先天免疫系统来保护其植物宿主。本工作对内生细菌多样性的现状、它们在植物上的定殖策略以及它们在作物生产力的产前和产后阶段作为植物病害保护剂的潜在作用进行了系统和深入的综述。此外，还探讨了通过减少/消除有毒农用化学品的使用来实现内生细菌对可持续农业的有益影响。最后，我们提出了在产前和产后阶段将内生细菌作为生物制剂应用的多种有效策略，旨在保护作物植物及其农产品。
