In 1904, Lorenz Hiltner´s definition of the „Rhizosphere “ highlighted the key importance of beneficial microbial colonization of plant roots for plant nutrition and health. Since then, numerous rhizosphere microbes were isolated and characterized in order to enhance plant growth based on beneficial interactions. Negative impacts of chemically based high-input agriculture of the so-called „green revolution “, like environmental pollution, biodiversity loss, and climate impacts are obvious. In order to reduce such impacts on environmental and health risks a „second green revolution “ is needed using biological and ecological processes in a sustainable agricultural context. Molecular interaction studies of rhizosphere microbes with plants provided deep insights into tight interactions within plant–microbe holobionts involving microbially produced phytohormones, volatile substances, bacterial quorum sensing molecules and fungal lipochitooligosaccharides, which all have important plant health stimulatory activities. However, some rhizosphere microbes are closely related to plant and human pathogens, making careful genomic and pathogenic screenings necessary before field applications are allowed. Nowadays, many beneficial rhizosphere microbes and microbial metabolites are applied successfully to combat phytopathogens and support plant nutrition. In all biotechnological applications, the Nagoya protocol on implications for access and benefit sharing related to natural genetic ressources and biodiversity have to be followed. The rhizosphere harbors multiple microbial activities having diverse beneficial effects towards plant growth and sustainable agricultural practice, reflecting the„One Health concept “.
