Synergistic partnerships of endophytic fungi for bioactive compound production and biotic stress management in medicinal plants

Abstract

The fungal endophytes are an understudied area of research with great potential for new bioactive compounds’ discovery. These are the fungal strains that live within the inner compartments of the host plant without causing it any kind of harm. These fungal endophytes, in combination with the host organisms, synthesize many compounds with a range of pharmaceutical values. Most recently, the discovery of fungal endophyte genes which are linked with the biosynthesis of plant metabolites has opened a new field of research. These plant partners assist plants against biotic stress and protect them from pathogenic attacks or diseases with the presence of some important gene families like WRKY and MYB. The bioactive metabolites from this group are known for their anticancer, antimicrobial, antioxidant, antidiabetic, and anti-tubercular properties. Therefore, these bioactive compounds offer new routes for discovering novel drugs, which can boost the pharmaceutical industry in times of great demand for novel drugs. Extracellular enzymes are also produced within the members of this distinct group which are crucial for several industrial sectors, including the biofuel production industry. Furthermore, fungal endophytes are capable of synthesizing silver nanoparticles, which exhibit significant potential in fields like biomedical imaging and water purification. This article aims to document all the available data on this group of fungi living in medicinal plants and the major compounds produced by members of this distinct group that are in use for the therapy of various ailments.
