The rhizosphere, the soil region influenced by plant roots, harbours a diverse microbiome that plays a crucial role in plant health and disease resistance. Probiotic microorganisms in the rhizosphere, such as beneficial bacteria and fungi, contribute significantly to enhancing the functional capacity of the microbiome. These probiotics improve nutrient availability, suppress soilborne pathogens, and stimulate plant immune responses. This study highlights the impact of rhizosphere probiotic diversity on microbiome functionality and plant disease resistance. A diverse probiotic community promotes the production of bioactive compounds, such as antibiotics, siderophores, and enzymes, which inhibit pathogenic microbes and improve plant growth. Additionally, probiotics modulate plant hormone levels, leading to systemic resistance against a broad spectrum of diseases. Our findings emphasize that maintaining a high diversity of rhizosphere probiotics is essential for sustaining a resilient microbiome capable of protecting plants from biotic stresses. Integrating these insights into agricultural practices, such as the application of probiotic inoculants, could enhance sustainable crop production by reducing the reliance on chemical inputs. This study underscores the need for further research on the ecological dynamics of rhizosphere probiotics and their potential for improving plant disease resistance in various agricultural systems.
