Microbial Endophytes: Functional Biology and Applications focuses on endophytic bacteria and fungi, including information on foundational endophytes and the latest advances in relevant genomics, proteomics and nanotechnological aspects. The book provides insights into the molecular aspects of plant endophytes and their interactions and applications, also exploring the potential commercialization of endophytic microorganisms and their use as bio fertilizers, in biocontrol, and as bioactive compounds for other sustainable applications. Coverage of important and emerging legal considerations relevant to those working to implement these important bacteria in production processes is also included.

• Presents discussion on entry, colonization and the distribution of endophytic microorganisms
• Explores the phyto immunological functions of endophytic microorganisms
• Provides genomic insights on plant endophyte interaction
• Identifies bio-commercial aspects of microbial endophytes for sustainable agriculture, including potential legal issues and IPR in microbial research

Abstract

Inside plants, microbial communities live as endophytes without causing any disease symptoms or adverse impacts to the host plant. These microbial communities may comprise bacteria, fungi, and archaea. In the last few decades endophytic microbes have been broadly used in sustainable agriculture as biofertilizers, biocontrols, or inducers of abiotic stress tolerance. Successful colonization by endophytes in the host plant is a key factor for beneficial plant microbe interaction that results in various plant growth promoting mechanisms. Colonization includes a series of phenomenon such as attachment, entry, motility, transmission, and multiplication of endophytic populations within the host plant. In this chapter, we will discuss the mechanisms of colonization, the rhizophagy cycle, and genomic insights of endophytic behavior and functions that will aid in the advancement and application of endophytes in various aspects of sustainable agriculture.
