Abstract
Plant growth-promoting rhizobacteria (PGPR) are indispensable part of rhizosphere microbiota that grow in association with the host plants and stimulate the plant growth. PGPR microcosm establishes in soil ecosystem because of its adaptability in varied environments with faster growth rate and biochemical versatility. In recent years researches have emphasised the key role of PGPR in improving nutrition and productivity of important crops with therapeutic and industrial significance. Hence, therefore, the present chapter highlights PGPR-mediated acquired systemic resistance against phytopathogens and insect pests involving mechanisms of action. Field applications of PGPR-mediated results reflect their substantial role in inducing systemic resistance in crop plants.
