Plant-Microbe Interactions

Living reference work entry

Key Concepts

  • Globally, the majority of nitrogen and phosphorus uptake by plants is mediated by mutualistic root microbes, which form intricate and complex biochemical and genetic interactions with plants.

  • Plant leaves host a variety of beneficial bacteria and fungi that contribute to plant nutrition and/or defense against pathogens.

  • In addition to mutualistic bacteria intimately associated with roots, there exist plant growth-promoting rhizobacteria more loosely associated with roots that contribute to plant nutrition, protection from pathogens, and environmental stress reduction.

  • The region surrounding roots, the rhizosphere, is a dynamic environment, rich in chemical communication among plants and microbes, where nutrient cycling is altered by root exudation and heightened microbial activity.

  • Plants profoundly impact the biogeochemical cycling activities of soil microbes through their effects on microclimate and soil chemistry.

  • Plants and microbes collaborate to produce soil organic...
