Microbiome in Plant Health and Disease: Challenges and Opportunities

  • Ranjini Ramesh


In this chapter, the role played by the “plant microbiome” has been discussed in detail, with reference to their diversity, mechanisms of growth promotion in plants, and methods of their defense against predators and disease. The effects of plants on the diversity of the microbiome, and “co-adaptation” between the two have also been elaborated. The mechanisms of biocontrol detailed are “antagonism,” “signal interference,” “predation,” “parasitism,” “induced systemic resistance,” and the role played by ferric ions. Direct plant growth promotion methods discussed are “rhizoremediation,” “phytostimulation,” and “stress control,” among others. The diversity of the rhizosphere microbiome has also been detailed, with reference to Azotobacter, Azospirillum, mycorrhizae, and blue-green algae.
