Food security is one of the most challenges in the world. This problem is more important in regions with unsuitable agricultural system conditions. Use of chemical pesticides to protect crops against plant pathogens and insects has been increasing over the last decades. Chemical fertilizers increase the yield but usually reduce soil fertility and harm to environment. Therefore, application of endophytic bacteria as alternative fertilizers can be used in sustainable agriculture without affecting environment. Endophytic bacteria use various mechanisms to enhance plant growth such as nitrogen fixation, solubilization of phosphate, production of phytohormones like auxin, cytokinin and gibberellin, production of Hydrogen cyanide and Siderophore as an antimicrobial compounds to control of soilborne disease and increasing plant resistance to abiotic disorders. Knowledge about endophytic bacteria- plant interaction can provide effective strategy to develop sustainable agriculture in order to ensure yield improvement without affecting environment.

Khezri, M., Karimi Shahri, M. R., & Ghasemi, A. (2023). Bacterial rot disease of saffron corm and leaf. Plant Pathology Science, 12(1), 74-83. Doi: 10.2982/PPS.12.1.74
Saffron is one of the valuable agricultural products and its dried stigma is used as medicine and is known as a precious spice. Infection of the plant's reproductive organs plays an important role in the spread of pathogens. The saffron is reproduced via corms, and using healthy and pathogen-free corms is the best and most effective strategy to prevent the spread of soil-borne pathogens in new areas and fields. Saffron corm rot disease is caused by some fungal and bacterial pathogens. Burkholderia gladioli pv. gladioli is the causal agent of saffron leaf and corm rot disease. The bacterium survives in the soil for a long time, and it is transmitted through the infected soil, farming tools, and corms. In recent years, this disease has been reported from Khorasan Razavi province. In this article, along with introducing the bacterial disease of saffron leaves and corms rotting, strategies to prevent the occurrence and spread of the disease have been presented.
