Abstract Background The common Eastern bumble bee Bombus impatiens is native to North America and is the main commercially reared pollinator in the Americas. There has been extensive research on this species related to its social biology, applied pol

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

Here we give names to three new species of Paraburkholderia that can remain in symbiosis indefinitely in the spores of a soil dwelling eukaryote, Dictyostelium discoideum. The new species P. agricolaris sp. nov., P. hayleyella sp. nov., and P. bonnie

Symbiont location, host fitness, and possible coadaptation in a symbiosis between social amoebae and bacteria

Autor: Longfei Shu, Debra A Brock, Katherine S Geist, Jacob W Miller, David C Queller, Joan E Strassmann, Susanne DiSalvo

Publikováno v: eLife, Vol 7 (2018)

Recent symbioses, particularly facultative ones, are well suited for unravelling the evolutionary give and take between partners. Here we look at variation in natural isolates of the social amoeba Dictyostelium discoideum and their relationships with

Co-expression gene networks and machine-learning algorithms unveil a core genetic toolkit for reproductive division of labour in rudimentary insect societies

Autor: Emeline Favreau, Katherine S Geist, Christopher D R Wyatt, Amy L Toth, Seirian Sumner, Sandra M Rehan

Publikováno v: Genome biology and evolution.

The evolution of eusociality requires that individuals forgo some or all their own reproduction to assist the reproduction of others in their group, such as a primary egg-laying queen. A major open question is how genes and genetic pathways sculpt th

Loss and resiliency of social amoeba symbiosis under simulated warming

Autor: Xinye Qian, David C. Queller, Debra A. Brock, Longfei Shu, Joan E. Strassmann, Katherine S Geist

Publikováno v: Ecology and Evolution

Anthropogenic global change is increasingly raising concerns about collapses of symbiotic interactions worldwide. Therefore, understanding how climate change affects symbioses remains a challenge and demands more study. Here, we look at how simulated

Family quarrels in seeds and rapid adaptive evolution in Arabidopsis

Autor: Joan E. Strassmann, David C. Queller, Katherine S Geist

Publikováno v: Proceedings of the National Academy of Sciences. 116:9463-9468

Evolutionary conflict can drive rapid adaptive evolution, sometimes called an arms race, because each party needs to respond continually to the adaptations of the other. Evidence for such arms races can sometimes be seen in morphology, in behavior, o

Genetic signatures of microbial altruism and cheating in social amoebas in the wild

Autor: Xiangjun Tian, David C. Queller, Katherine S Geist, Suegene Noh, Joan E. Strassmann

Publikováno v: Proceedings of the National Academy of Sciences. 115:3096-3101

Many microbes engage in social interactions. Some of these have come to play an important role in the study of cooperation and conflict, largely because, unlike most animals, they can be genetically manipulated and experimentally evolved. However, wh
