| ABSTRACT |
| The excessive reliance on chemical inputs for managing soil nutrients and pathogens has raised concerns about their long-term sustainability and environmental impact. In contrast, the use of soil microbes offers an eco-friendly and efficient alternative for improving soil fertility and plant growth. Beneficial microorganisms, including plant growth-promoting rhizobacteria (PGPR), mycorrhizal fungi, and other soil organisms, play pivotal roles in nutrient cycling, organic matter decomposition, and nutrient availability improvement. This review explores the potential of leveraging microbial resources for sustainable soil nutrient management and resilient crop production. It delves into the intricate interactions between host plants and PGPR, particularly under nutrient-limited and fluctuating environmental conditions, with a focus on the molecular signaling pathways and mechanisms regulating these relationships. Furthermore, it emphasizes the role of advanced techniques and PGPR-responsive microRNAs to uncover the functional capabilities of microbial communities and their dynamic interactions with plants. These approaches pave the way for developing innovative, microbe-based strategies to optimize nutrient use efficiency, reduce dependency on synthetic fertilizers, and support sustainable agricultural practices. |
