    Proc Natl Acad Sci U S A 102:390-5. 2005
    ..Our results parallel a variety of conflict mediation mechanisms existing in nature: evolution of reduced genomes in symbionts, cotransmission of partners, and obligate coexistence between cooperating species...
  3. pmc A shift to parasitism in the jellyfish symbiont Symbiodinium microadriaticum
    Joel L Sachs
    Section of Integrative Biology, Patterson Laboratories, 1 University Station C0930, University of Texas, Austin, TX 78712 0253, USA
    Proc Biol Sci 273:425-9. 2006
    ..Our results demonstrate the dynamic nature of this symbiosis and illustrate the potential ease with which beneficial symbionts can evolve into parasites...

    Joel L Sachs
    University of California Berkeley, Department of Integrative Biology, Berkeley, CA 94720, USA
    Trends Ecol Evol 21:585-92. 2006
    ..By contrast, diverse systems exhibit reversions to autonomy, and this might be a common and unexplored endpoint to mutualism...

    J L Sachs
    Integrative Biology, University of California, Berkeley, CA, USA
    J Evol Biol 23:1075-89. 2010
    ..This is the first study to reveal the adaptive nature of rhizobial cheating and to trace the evolutionary origins of uncooperative rhizobial mutants...
  7. doi request reprint Host control over infection and proliferation of a cheater symbiont
    J L Sachs
    University of California, Riverside, CA 92521, USA
    J Evol Biol 23:1919-27. 2010
    ..These results can explain how a rapidly growing cheater symbiont--that exhibits a massive fitness advantage in single infections--can be prevented from sweeping through a beneficial population of symbionts...

    J L Sachs
    Department of Integrative Biology, University of California, Berkeley, California 94720, USA
    Appl Environ Microbiol 75:4727-35. 2009
    ..This pattern suggests that host infection provides ample rewards to symbiotic bacteria but that host specificity can strongly structure only a small subset of the rhizobial community...

    Q Rev Biol 79:135-60. 2004

    Ellen L Simms
    Department of Integrative Biology, University of California, 3060 Valley Life Sciences Building 3140, Berkeley, CA 94720, USA
    Proc Biol Sci 273:77-81. 2006
