The bacterial wilt caused by Ralstonia solanacearum is a destructive plant disease globally. Since a completely non-biol. control measure could be a matter of environmental concern, investigations of developing eco-friendly strategies are required to control this phytopathogen. Attenuation of the bacterial virulence in addition to destroying the pathogen may be an alternative and overarching approach to control this disease. In this study, we have explored the potentiality of a vertically transmitted endophytic fungus Penicillium sp. PM031 isolated from stem of in vitro grown, wilt susceptible tomato cultivar to control this phytopathogen. The endophytic fungus was unable to inhibit the bacterial growth during direct confrontation in co-culture system; rather its growth and extracellular secretion were affected by the bacterium. Interestingly, the PM031-derived endo-metabolites, containing 鈭?0% of lipid mols., showed the dose-dependent growth inhibitory effect against R. solanacearum. Metabolite treatment with a concentration of 2500 and 5000渭g/mL significantly inhibited the bacterial growth 24.72% and 64.31%, resp. Higher concentrations of endo-metabolite treatment exhibited antibacterial activity by rupturing cellular membranes. Furthermore, the endo-metabolites neg. influence the virulence factors necessary in early phases of bacterial infection, such as motility and biofilm formation. Our study highlights even if an endophytic fungus associated with the susceptible host plant cannot tackle R. solanacearum directly, its lipid-rich metabolites have potential to attenuate the virulence of phytopathogen. We believe this study can be a stepping stone to develop suitable formulations to control the bacterial wilt in a sustainable way, which will reduce excessive uses of synthetic bactericides.

This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1SDS of cas: 31566-31-1).
Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.SDS of cas: 31566-31-1
