WebThe double mutants can also inhibit pheromone signaling (and will even complementgpa1Δ) but only when overexpressed (data not shown). In comparison, a 2-fold overexpression of wild-type GPA1 led to a more modest inhibition of the pheromone response, and the double-site mutants were without effect (Fig. 2 A). The mutant and wild-type forms of ... WebA pheromone is a secreted chemical signal used to trigger a response in another individual of the same species. Pheromones are especially common among social insects, such as ants and bees. Pheromones may attract the opposite sex, raise an alarm, mark a food trail, or trigger other, more complex behaviors.

Other ants in the colony can use their antennas to detect these pheromones and respond accordingly.
