Reduced social function in experimentally evolved Dictyostelium discoideum implies selection for social conflict in nature

T. Larsen, I. Jahan, D. A. Brock, J. Strassmann, D. Queller

This study shows that experimentally evolved Dictyostelium discoideum lost traits related to social conflict when selective pressures were removed, suggesting these traits are adaptations to natural social interactions.

Resource-combining costs of being a diet generalist in the super-generalist protist predator Dictyostelium discoideum

P. M. Shreenidhi, D. A. Brock, R. I. McCabe, J. E. Strassmann, D. C. Queller

This study investigates resource-switching and resource-mixing costs in the protist predator Dictyostelium discoideum, showing growth rate reductions when switching or mixing bacterial prey.

Symbiotic bacteria, immune-like sentinel cells, and the response to pathogens in a social amoeba

T. J. Scott, T. J. Larsen, D. A. Brock, S. Y. S. Uhm, D. C. Queller, J. E. Strassmann

This study examines how Paraburkholderia endosymbionts affect sentinel cell function in D. discoideum, revealing both immune suppression and toxin protection effects.

Loss of altruism in the social amoeba Dictyostelium discoideum is associated with the G protein-coupled receptor grlG

L. M. Walker, R. N. Sherpa, S. Ivaturi, D. A. Brock, J. R. Walker, J. E. Strassmann, D. C. Queller

The paper identifies genomic changes in Dictyostelium discoideum that correlate with the loss of cooperation and altruism, highlighting the role of the grlG gene.

A complex symbiosis involving within species variation in the response of Dictyostelium amoebae to Burkholderia bacteria

L. Shu, D. A. Brock, K. S. Geist, J. W. Miller, D. C. Queller, J. E. Strassmann, S. DiSalvo

The paper examines variation in Dictyostelium discoideum's response to Burkholderia symbionts, finding that natural hosts tolerate their symbionts better than others.

Endosymbiotic adaptations in three new bacterial species associated with Dictyostelium discoideum: Burkholderia agricolaris sp. nov., Burkholderia hayleyella sp. nov., and Burkholderia bonniea sp. nov.

D. A. Brock, A. M. Hubert, S. Noh, S. DiSalvo, K. S. Geist, T. S. Haselkorn, D. Queller, J. E. Strassmann

The paper describes three new Burkholderia species that can persist within Dictyostelium discoideum spores, distinguished by their unique traits and symbiotic capabilities.
