  • Rhizobium, which is the nitrogen fixing bacteria on legumes 'roots and is quite necessary and beneficial for plant growth.

    Chapter 6

  • Beneath the rosette of leaves, a large mass of roots has the ability to form nitrogen-fixing nodules called Rhizobium which are filled with beneficial bacteria that can take nitrogen from the atmosphere and feed the plant.

  • Long's lab studies the symbiotic interaction of Rhizobium bacteria and alfalfa roots to form nodules.

    Sharon R. Long: Science under the Obama Administration

  • Examples of mutualisms include Rhizobium bacteria growing in nodules on the roots of legume plants, insects pollinating the flowers of angiosperms, or cleaner fish and client fish.

    Community ecology

  • These include the bacteria species Rhizobium, which lives on the root nodules of legumes, and cyanobacteria (sometimes called blue-green algae), which are ubiquitous to water and soil environments.

    AP Environmental Science Chapter 2- The Cycling of Matter

  • Examples include lichens (a symbiosis between a fungus and an alga), as well as associations between mycorrhizal fungi and plants, between Rhizobium bacteria and legumes, and between corals and zooxanthellae.


  • Or like the flagellar motor which we see in Rhizobium and many other bacteria.

    Scientists' Responses Solicited

  • Species of Rhizobium bacteria invade the roots of legume plants and convert abundant nitrogen in the air into a form that the plant can use directly to make amino acids and thus proteins.

    On Food and Cooking, The Science and Lore of the Kitchen

  • Through a symbiotic relationship with Rhizobium soil bacteria these species are able to fix atmospheric nitrogen into a form they can use for growth.

    Chapter 3

  • I also conducted some inoculant trials with Rhizobium donated by a professor from Trier University in Germany who is conducting studies in this area.
