11. It is mainly found in heterogeneous and complex environments, such as soil and rhizosphere . 12. In Molecular Microbial Ecology of the Rhizosphere . 13. Mineral nutrients are mainly acquired by roots from the rhizosphere and are subsequently distributed to shoots. 14. Competition for iron also serves as a strong selective force determining the microbial population in the rhizosphere . 15. Endophytes are distinct from mycorrhizal fungi or rhizosphere microbes in that they live entirely within the plant. 16. It was first isolated from the rhizosphere of a specimen of " Lactuca sativa ". 17. "Arabidopsis thaliana " is an rhizosphere bacteria such as " Bacillus megaterium ". 18. Plant responses to environmental cycles may even induce indirect cycles in rhizosphere microbial activities, including nitrogen fixation. 19. These specialized roots tolerate high carbon dioxide concentrations, oxidize the rhizosphere , and carry on anaerobic respiration. 20. AMF contributes a substantial amount of carbon to the rhizosphere through the growth and degeneration of the hyphal network.
