In conclusion, our data provide evidence that quorum sensing is involved in controlling the response to iron limitation.
Integration of quorum sensing with nutrient limitation response seems sensible from a physiological point of view.
In most cases, quorum sensing functions to induce gene expression at high culture densities where nutrient limitation is a major constraint for bacterial growth.
Historically, majorities have benefited by the standard quorum rule, which counts all those physically present as contributing to the quorum.
Suppose a hundred-member body, a standard simple-majority scheme, and a quorum of fifty-one attenders, all of whom vote.
Although quorum rules do partially promote the aim of majoritarian control, they do so only in a sharply limited fashion.
Other studies have documented an overlap between nutrient limitation response and quorum-sensing-controlled gene expression.
This may have some relevance to a quorum-sensing mechanism.
