Flashcards in Cooperation in D. discoideum Deck (4)
Dictyostelium discoideum (slime moulds) are usually solitary, but they aggregate in times of starvation. Genetically diverse clones come together to form a slug for movement. Cells differentiate into the stalk and fruiting body. The fruiting body produces spores and disperse whereas stalk cells will die. Who found this?
Many cheater mutants discovered that preferentially migrate to pre-spore region. The cheater phenotype of D. discoideum produces more spores than the wildtype, yet this is deleterious to the colony in the long-term as the more cheaters in the population produces fewer fruiting bodies overall. Cheater gene termed fbxA-. Who found this?
Gilbert et al., 2007.
Who looked at evolution under two lines of relatedness and found that relatedness restricted the evolution of cheating?
Kudzai-Fick et al., 2012.
