Cooperation, conflict, and experimental evolution in social amoebae
Cooperation and cheater control have helped shape life as we know it, but there is still much to learn. A eukaryote microbial model organism, like Dictyostelium discoideum , is an excellent system for advancing our ...
Evolutionary costs and benefits of a newly discovered symbiosis between the social amoeba Dictyostelium and bacteria
Recent work has shown that microorganisms are surprisingly like animals in having sophisticated behaviours such as cooperation, communication, and recognition, as well as many kinds of symbioses. Here we show first that ...
Cloning and sequencing of genes involved in glycolysis from Clostridium acetobutylicum
Complementation studies were carried out with a Clostridium acetobutylicum ATCC 824 plasmid library and Escherichia coli glycolytic mutants. Degenerate primers were designed from homologous regions in known glycolysis ...
Exploiting new terrain: An advantage to sociality in the slime mold Dictyostelium discoideum
Identifying benefits to cooperation is important in studying social evolution. When the social amoebae of Dictyostelium discoideum starve, they aggregate to form multicellular slugs that migrate towards the soil surface ...
Symbiosis lost: Imperfect vertical transmission of fungal endophytes in native grasses
Vertically transmitted symbionts associate with some of the most ecologically dominant species on Earth, and their fixation has led to major evolutionary transitions (e.g., mitochondria, chloroplasts). While transmission ...
