Viability of Rhizobium bacteroids.

H C Tsien, P S Cain, E L Schmidt

    Applied and Environmental Microbiology
    |December 1, 1977
    PubMed
    Summary

    Bacteroids, the symbiotic bacteria within legume nodules, demonstrated high viability (90%) in soybean and bean plants. This finding challenges the long-held belief that these essential microorganisms are nonviable.

    Area of Science:

    • Plant-microbe interactions
    • Legume symbiosis
    • Bacteriology

    Background:

    • Bacteroids are differentiated forms of Rhizobium bacteria residing within legume root nodules.
    • Prevailing scientific consensus suggested bacteroids have limited viability.
    • Understanding bacteroid viability is crucial for nitrogen fixation efficiency.

    Purpose of the Study:

    • To assess the viability of bacteroids isolated from soybean and bean nodules.
    • To challenge or confirm the existing understanding of bacteroid viability.
    • To investigate factors influencing bacteroid viability.

    Main Methods:

    • Bacteroids were isolated from soybean and bean root nodules.
    • Standard viability testing methods were employed.
    • Viability was assessed across different Rhizobium strains and nodule ages.

    Main Results:

    • Bacteroids exhibited an average viability of 90%.
    • High viability was consistent across various Rhizobium strains.
    • Nodule age and environmental conditions did not significantly impact bacteroid viability.

    Conclusions:

    • Bacteroids possess a significantly higher viability than previously assumed.
    • Legume bacteroids are viable and functional within the nodule environment.
    • This research necessitates a re-evaluation of bacteroid physiology and symbiotic function.
