Abstract

A plethora of knowledge on the role of endophytic microorganisms has been reported in recent years. The cooperative chemistry between the endophytes and the internal host tissue has turned them into a crucial aid for biotechnological applications. Microbial endophytes are ubiquitous among most plant species on earth and contribute to the benefit of host plants by generating a wide range of metabolites that provide the plant with survival value. Endophytes can either directly stimulate plant growth by producing phytohormones or indirectly stimulate plant growth by increasing the availability of soil nutrients to plants. Endophytes may also help suppress diseases in plants directly by neutralizing environmental toxic elements, and by inhibiting plant pathogens by antagonistic action, or indirectly by stimulating induced plant systemic resistance. Several natural compounds produced by endophytes as secondary metabolites are beneficial to both plants and humans. This is why endophytes are regarded as a significant source of novel natural products of value in modern medicine, agriculture, and industry. Endophytes are known for producing pigments, bioactive compounds, and industrially important enzymes, like glucanase, amylase, laccase, etc. Some endophytes can also produce nanoparticles that potentially have numerous applications in a variety of fields. They also play an important role in biodegradation and bioremediation, both of which are beneficial to the environment and ecology. In this review, we highlighted potential biotechnological applications of endophytic microbes, as well as their diverse importance in plant growth and public health.
