Summary: | 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. |
