Microbial symbioses are essential for the normal development and growth of animals1, 2, 3. Often, symbionts must be acquired from the environment during each generation, and identification of the relevant symbiotic partner against a myriad of unwanted relationships is a formidable task4. Although examples of this specificity are well-documented, the genetic mechanisms governing it are poorly characterized5. Here we show that the two-component sensor kinase RscS is necessary
