Secondary metabolites of fluorescent pseudomonads in biocontrol of phytopathogens for sustainable agriculture

摘要: Abstract Plant growth promoting rhizobacteria (PGPR) belonging to the group “fluorescent pseudomonads” play very important role in sustainable agriculture. They are well known assist plants’ health by diverse mechanisms. Potential of fluorescent pseudomonads protect plants from a range phytopathogens is prime importance and gained momentum agri-biotechnology. At global level commercialization form bioinoculants for management several plant diseases now considered be effective. Fluorescent being used as effective biocontrol agents (BCA) against an array phytopathogens. have great potential BCA because ability produce variety secondary metabolites. Therefore, objective this review describe assess roles metabolites produced controlling enhancing health. Prominent involved include phenazines (PHZ), 2, 4-diacetylphloroglucinol (DAPG), pyoluteorin (PLT), pyrrolnitrin (PRN), cyclic lipopeptides (CLPs) volatile organic compounds (VOCs) such hydrogen cyanide (HCN). These antifungal, antibacterial, antiviral, antitumor anti-nematicidal properties. Better contemporary techniques extraction, purification characterization may unveil mechanisms action these enable utilize them future bioformulations so replace harmful synthetic chemicals (in agriculture).
