Plant Root and Rhizosphere Ecosystem

The plant root and rhizosphere ecosystem is the narrow zone of soil surrounding plant roots that is directly influenced by root secretions and associated soil microorganisms [1]. This ecosystem serves as a critical interface for nutrient acquisition, water uptake, and protection against soil-borne pathogens through the recruitment of beneficial microbes [2]. It is characterized by the release of root exudates—such as sugars, organic acids, and amino acids—which act as signaling molecules and carbon sources for the rhizosphere microbiome [3]. While not a single molecular target, it is a primary focus for agricultural biotechnology to enhance crop yield and resilience through the application of biostimulants and microbial inoculants [4]. Understanding the rhizosphere is essential for developing sustainable agricultural practices and managing plant health in the face of environmental stress [5].
