Lipid-rich endo-metabolites from a vertically transmitted fungal endophyte Penicillium sp. PM031 attenuate virulence factors of phytopathogenic Ralstonia solanacearum.

The bacterial wilt caused by Ralstonia solanacearum is a destructive plant disease globally. Since a completely non-biological 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.
