Title : Plant-associated bacteria as bioindicators and enhancers of sustainable agricultural systems
Abstract:
Plant-associated bacteria play a critical role in maintaining ecosystem balance and improving agricultural productivity. These microorganisms, including rhizobacteria and endophytic bacteria, interact closely with plants, influencing nutrient cycling, soil fertility, and plant health. Due to their high sensitivity to environmental changes and their rapid response to stress conditions, bacterial communities are increasingly recognized as reliable bioindicators of soil quality and environmental sustainability. This study explores the dual function of plant-associated bacteria as both bioindicators and bioenhancers in agricultural ecosystems. By analyzing bacterial diversity and abundance under varying environmental conditions, including soil contamination and climate stress, the research highlights how shifts in microbial communities reflect ecosystem health. Furthermore, beneficial bacteria such as plant growth-promoting rhizobacteria (PGPR) contribute to enhanced plant growth through nitrogen fixation, phytohormone production, and pathogen suppression. The findings emphasize the importance of integrating microbial-based approaches into modern agricultural practices to support sustainable crop production and environmental resilience. This research aligns with current advancements in plant science and molecular biology by bridging microbial ecology with plant biotechnology, offering innovative solutions for sustainable agriculture and ecosystem monitoring.
