Phenolic compounds (polyphenols/phenolics) are the plants' secondary metabolites produced for defense purposes. The ubiquitous nature of phenolics describes their functional diversity. They have noteworthy impact on different physiological and metabolic processes plant. These act as antimicrobial, antifungal, antioxidant agents that intercept microbial invasions. Phenolics also play structural role in plants provide integrity, vigor, vitality to plant cells. Plant phenolic system includes physical alterations (suberization or lignification), changes (de novo biosynthesis pathogenesis-related proteins), synthesis, accretion phenylpropanoid-derived (phytoalexins). dual function both attractants repellents organisms around plants. protect from damage caused by pathogens other microbes. various defensive mechanisms shield invading pathogens. Moreover, being weak acids, such anthocyanins, hydroxycinnamic acid (HCAs), flavonoids free radicals scavenging potential is accumulative under stress prevents oxidative stress. In addition, an important rhizospheric signaling molecules attract symbiotic (Rhizobium) well pathogenic microbes (Agrobacterium). Thus, they developing plant–microbial interactions.

Plants face many biological and non-biological challenges throughout their life cycle, from seed to harvest. These have recently increased due climate changes. Strategies for confronting different types of stresses depend on the type stress, cultivated plant, climatic conditions, soil characteristics, water variables, cost, management system. Chemical methods (fertilizers pesticides) been widely used manage abiotic biotic stresses, but they raise concerns about environmental contamination, toxic residues, development resistant pathogens. Eco-friendly strategies become one most important approaches obtaining high-quality quantitative plant-based products. Microbial inoculants, such as plant growth-promoting microorganisms (PGPM), offer a sustainable alternative chemical methods. PGPM can augment growth nutrition, improve tolerance reduce certain They employ variety mechanisms alleviate stressors boost resilience, including nutrient assimilation, production metabolites, activation systemic resistance.
