a
Proteins listed produce a pheromone that triggers cells to increase synthesis of that protein and the pheromone that it produces. In some cases, positive feedback also triggers production of more pheromone receptor.
b
Indicates organisms outside the Proteobacteria that produce non-HSL pheromones.
