When can syntrophic microbial cooperation win over selfish cheaters? ecoevocommunity.nature.com/pos

Eco-evolutionary modelling of microbial #syntrophy indicates the robustness of cross-feeding over cross-facilitation nature.com/articles/s41598-023

Most #prokaryotes rely on syntrophic partners, but they rarely evolve to full #endosymbiosis. If #mitochondria have originated from a syntrophic #symbiosis, a burning question arises: Why aren't there more #prokaryotic syntrophies that turn into endosymbiosis?

Models of microbial cross-feeding (left) and cross-facilitation (right). Blue and yellow microbes produce waste (left) or enzymes (right) which convey some benefit for the other (being eaten or making a resource consumable). Cheater (red) may appear that do not invest in production but enjoy benefits. Bottom figures show how the trait z of cooperative behaviour can evolve in an adaptive dynamics scenario: for cross-feeding, most of the simulations (each trajectory) lead to a nonzero level of cooperation. For cross-facilitation, mutations lead the population to the ultimate loss of cooperation (z ≤ 0).
