Endophytic Association: What, Why, and How focuses on the endophytic association of plants, how they have originated inside the host, their importance, and how they are beneficial for the environment, as well as humans. The book discusses how using endophytic microbes in agricultural fields can be enriched without impacting environment negatively, and how they can be utilized for pharmaceutical purposes, including bioremediation. It includes advanced and up-to-date information, as well as future directions for young researchers and scientists who are working in the field of agriculture, pharmaceuticals, bio nanotechnology and bioremediation of environmental contaminants for environmental protection and sustainable development. - Details the underlying mechanisms of endophyte-host association and their signaling mechanisms - Describes numerous, successful field studies on the different applications of nanoparticles produced by endophytes (bio-nanotechnology) for sustainable development - Presents recent advances and challenges in endophyte-associated bio-remediation research and applications for human health - Provides information on bioactive compounds produced by endophytes for pharmaceutical purposes
